Spread Hopper Layout



1.3.1 Aggregate Spreading System & Controls

The ‘SPC10e’ uses the ‘Phoenix’ Variable Width SpreadingHopper system. This consists of three individual spreadinghoppers, each similar in design and operation [See fig. SE902-06]. These are –

Centre section spreading hopperLH extension spreading hopperRH extension spreading hopper

Each hopper is fitted with the same aggregate metering devicethat accurately controls both

the volume of aggregate spread (application rate)andan even spread coverage over the full spread width(transverse distribution).

The aggregate metering device consists of –

A distribution roller (FeedRoller), at the base of thehopper, that rotates. As it rotates the aggregate istaken out of the bottom of the hopper and is propelledforward and deflected downward to the road surfaceby the Scatter Plate.Starting and stopping the feedroller starts and stopsthe spreading of aggregate.

A control blade (FeedGate) directly above theFeedRoller sets the volume of aggregate the FeedRollertakes for the hopper as it rotates.Its lower section is rubber, which allows large, miss-shaped aggregate or debris to pass without damage tothe spreading system or disruption to an evenapplication rate.

The ‘SPC10e’ Aggregate Metering SystemThe metering system ensures the application rate remains thesame even if the machines ground speed changes. As groundspeed increases the rotational speed of the feedroller willincreases and vice-versa. The higher the proportion of feedrollerspeed to ground speed the higher the application rate will be.

The three feedrollers (RH extension/centre/LH extension) arelinked together so their rotational speeds will always be thesame.



Spreading Hopper – Feedgate Adjustment

Dia SK101-01A



The metering system will not be able to maintain applicationrate over a wide speed range. Do not start the feedrollers fromstationary and then increase to normal operating speed. Themetering system must operate in a band around the normaloperating speed, i.e. if 3.5 kph is set as maximum speed onground speed controller, then do not spread below 2.5kph.

To maintain the highest accuracy, set the ground speedcontroller to ensure the ‘SPC10e’ matches the bitumendistributor speed. Maintain this speed unless changing supplytrucks over. Build the machines speed to spreading speed beforestarting the spreading operation.

Control of Application RateThe Front Spreading Hoppers must be ‘set-up’ to the size/type ofaggregate and the application rate (kgs/mtr2 or ltrs/mtr2) beforestarting to spread with a new aggregate. This means thefollowing adjustments have to be made [see dia SK101-01A] –

The rotational speed of the feedroller must be set tothe relative ground speed.

This can be adjusted both before & duringspreading.

The gap set above the FeedRoller, by the FeedGate.The feedgate is set to a f ixed gap, remaining setuntil re-adjusted when the machine is stationary.

Feedroller Speed AdjustmentThe rotational speed proportion is controlled by the ‘SpreadRate’ dial on the RH console. Turn dial clockwise toincrease application rate and anti-clockwise to decrease.

IMPORTANT:The feedroller must not turn too slowly, as itsrotational motion can become unsteady (starting tostutter). This will be seen in the finished surface withridges appearing in the new aggregate surface. Theminimum normal speed is 50 rpm.

The feedroller will proportion best in a speed range of75 rpm to 125 rpm. Try to keep the feedroller speed inthis range over the ground speeds used.

If the Ground Speed Controller is adjusted, the speedrate proportion will also be changed correspondingly.



FeedGate (Gap) AdjustmentThere are four separate FeedGates across the full width,two in the centre hopper and one each on the extensionhoppers. They are raised or lowered by their own screwadjusters.

The feedgate gap is set according to the spread speed inuse. Typical gap adjustments are –

• 0 to 2.0 kphtypical gap is two times aggregate sizei.e. for 10mm aggregate the gap should be 20mm

• 2.1 to 3.0 kphtypical gap is three times aggregate sizei.e. for 10mm aggregate the gap should be 30mm

• 3.1 to 4.2 kphtypical gap is four times aggregate sizei.e. for 10mm aggregate the gap should be 40mm

The application rate required may vary the gap settingoutside the typical levels given. Larger applications willneed a wider gap and lower output will require smaller gapsizes.

The feedroller speed must be set first and then the gapadjusted accordingly to obtain the required applicationrate.

The feedgate adjusters are spring loaded and can be raisedagainst the spring force. This allows for –

a. the passage of very large debris that can‘push-up’ the feedgate to pass;

b. clearing blockages by raising the feedgate tofull open, without changing the feedgatesetting;

c. raising the feedgate to allow very quick andlarge changes to gap setting to be made.

Important:a. Never set the feedgate gap below ‘1.5 times’ the

aggregate size; i.e. for 10mm aggregate theminimum gap must not be less than 15mm.

b. Always set all four feedgate gaps at the same level,this ensures the transverse distribution is evenover the full spreading width.

HAZARD WARNING:



DO NOT adjust the feedgates when the feedroller isrotating.

Operating Tips –When setting up the feedroller speed proportion allow forthe speed to be increased when in use. This allows forapplication rates to be changed ‘on the run’.

Once the set-up of feedroller speed proportion and feedgategap is achieved, a short run without spreading onto abitumen layer should be made to ensure the correctapplication rate and an even transverse distribution arebeing achieved.

Test the application rate according to section 1.3.9

The ‘Ground Speed Controller’ can be used to set amaximum spreading speed with the Joystick fully forward.This helps to prevent sudden movements and stops jerkingof the joystick when operating the Joystick mountedswitches.



FeedRoller Controls



Control of the FeedrollersThe feedrollers are switched ON to start spreading. Thefeedroller in each spreading hopper can be switch ON/OFFindependently of the others. The MASTER button in the joystickwill start all pre-selected feedrollers together and stop themwhen pressed again. A RED light in the joystick illuminateswhen the Master Switch is ON.

Pre-select the individual feedroller with their ‘blue’ switches inRH console. The feedrollers pre-selected will then start togetherwhen the Master Switch is ON. [See fig SE902-22C]

If the DELAY function on the Digital Meter is active, theextension hoppers feedrollers will start only when they reach theline where the centre hopper feedroller has started to spreadaggregate. Likewise, the extension hoppers will only stop afterthey reach the line where the centre hopper stopped spreading.

IMPORTANTWhen the DELAY is active, ALWAYS keep machinemoving until the extension hoppers have passed theline where they will stop automatically. Otherwisethey will operate out of sequence.

The Master ON/OFF will NOT operate when thetransmission is in HIGH speed range.

Front Hopper DUMP/AUTO/MAN Mode SwitchA three position switch sets the control mode of the feedrolleroperation.

AUTO Mode - normal position for spreading operation. In‘AUTO’ automatic proportioning mode, the roller speedchanges by joystick movement, ground speed controllermovement or spread rate control adjustment.

MAN Mode – To operate the feedrollers at a FIXEDspeed/output select the MAN position. The feedroller speedcan be set on the Spread Rate Controller. The feedrollerswill not vary their speed as ground speed varies.

DUMP Mode - to empty the front spreading hoppers ofunused aggregate (when changing size) the feedrollers canbe switched ON without the machine needing to move orthrough the MASTER switch. The switch must be held inthe DUMP position for the feedrollers to operate. All threefeedrollers will operate whether selected ON/OFF on theirindividual selector switches.



1.3.2 Control of Spreading Width

The ‘Phoenix’ Variable Width Spreading System allows forchanges in the spreading width both before and duringspreading. As the extension spreading hoppers have very littlewidth beyond their spreading width, the machine can also workvery close to the walls or other obstructions at the side of theroad.

The ‘Phoenix’ system uses the ‘free flow’ system to carry theaggregate to the outside of the extensions. No augers are used,reducing wear and tear on the machine.

The spreading width is set in two ways [see fig. SE902-12] –

a. Moving (extending or retracting) the Extension SpreadHoppers, the width of application can be reduced orincreased on each side.Each Extension Spreading Hopper can cover a fullspread from its full spread width of 878mm to aminimum of 56mm, in infinite steps.The extension hoppers are fitted with a mechanism tostop the section of the extension hopper still behind thecentre spread hopper from applying aggregate that wouldotherwise leave a double aggregate cover.

b. Reduce the Centre Spreading Hopper spreading widthfrom its 2368mm maximum by lowering the individualcut-off blades. These cut-off-blades cover the centrehopper width in eight sections of 296mm each. Eachblade may be individually set OPEN/SHUT.

The controls to raise or lower the cut-off-blades are located inthe RH console. The controls to move the extension hoppersIN/OUT are located in the Joystick.

Eight switches open/shut the cut-off-blades. All the bladesare also opened when the ignition switch is off.

Individual switches in the joystick move UP for extensionhopper OUT and DOWN for extension hopper IN. Attach thesight rods, stored on the conveyor sides, to the outside ofthe extension hoppers, to view their position. (Engine speedneeds to be 1800rpm to move extension hoppers).



Spread Width Controls

IMPORTANTIf moving IN a part filled extension hopper, alwaysswitch ON that feedroller so that aggregate does notbecome jammed inside.

The engine needs to be running at 1800rpm for theextension hoppers to move IN/OUT.

The Joystick control switches for the extensions willNOT work when the transmission is in HIGH speedrange.

Front Spreading HopperWidth of Spread Control

Viewed from Driver's Perspective



Operating Tips –The Extension Spreading Hoppers can vary infinitely

to the width of spread required. The Centre SpreadingHopper will change widths in steps of 296mm. Whenspreading narrow widths it is recommended to use part ofone extension hopper with part of the centre hopper (somecut-off-blades) shut, to achieve the spread width.

When the Extension Spreading Hoppers are almostfully out, the front hopper must be kept full of aggregate toensure the heap will naturally flow to the full width andnot lead to starvation at the very outside.

When spreading more than the centre hopper width,try to use both extension hoppers equally, rather than oneat almost full width and one not at all.

If operating on a side slope (camber) on the roadsurface, use the Extension Spreading Hopper on the lowerside of the slope to the greater width, as the aggregate flowinto it is improved.

The Extension Spreading Hopper will spread a width of56mm when fully IN (retracted). Therefore to stop spreadingthis width, that feedroller must be switched OFF.

With some aggregate and particularly sand, they willnot flow out to the full width. This will cause a reduction tothe maximum spreading width that can be covered. If thisoccurs, reduce the width until aggregate or sand covers theoutside of the feedroller in the extension hoppers by atleast 100mm or starvation will occur at times.



Effect of Spreading around Sharp BendsAdditional ‘deflector scatter plates’ are attached to the CentreSpreading Hopper for use when spreading around bends.

They are used to stop an uncovered area being left between theoutside extension hopper and the centre hopper, when spreadingaround bends. However, the ‘SPC10e’ is provided with a highsteering angle to assist when manoeuvring in tight areas. At fullsteering lock the machine will still leave an uncovered area,when using the adapter scatter plates.

The deflector scatter plates are located at either end of thecentre hopper scatter plate. They hinge DOWN to extend themain scatter plate and carry the aggregate further under thecentre hopper, before it falls onto the road surface. [See fig.SE902-07]

IMPORTANTThe adapter scatter plates must be hinged UP beforeloading the ‘SPC10e’ onto a transporting trailer.

Deflector Scatter Plate Positions



Power Operation of Deflector Scatter Plates (Optional)Optionally, the deflector scatter plates can be remotely lowered& raised, from the operators’ position. Switches for RH & LHsides are located in the RH Console. The adapter scatter platescan be set in their –

‘UP’ position – not in use‘DOWN’ position – in use

See diagram SE902-23D for switch location.

Cut-Off-Blade Switches x 8no. Deflector PlatesSwiches x 2no



Control of Overlap between Centre Hopper & Extension HoppersWhen the extension hoppers are retracted and move behind thecentre hopper, aggregate will not be spread immediately behindthe centre spread hopper. A plate in each extension hopper cutsoff the aggregate flow onto its feedroller over the length behindthe centre feedroller.

The cut-off plates for RH and LH are connected, by a single boltat the centre of the machine, between the two extensionhoppers.

With smaller aggregate sizes (10mm or lower) an overlap ofspread aggregate between the centre and extension hoppers mayoccur. This is due to the aggregate flowing back under the cut-off plate.

Extension Hopper Cut-Off Plate Adjustment



To compensate for any overlapped spread, the cut-off plate canbe offset outward. Move the cut-off plate outward by an amountsimilar to the overlap that can be seen. For an overlap of 25mmmove the cut-off door out by 20mm. [See fig SE902-08]

Remove the bolt holding the cut-off plates on the inside and usethe spacers supplied to offset the cut-off plate by placing thembetween the central bracket and the end of the cut-off plate.

IMPORTANTThe cut-off plate must not be offset outward by morethan 40mm. Otherwise the outside end will hit theend of the extension hopper, when fully retracted.

1.3.3 Types & Sizes of Aggregate for Spreading

The ‘SPC10e’ can spread a wide range of aggregate typessuccessfully, over varying application rates.

ImportantEnsure the spreading system is set-up correctly tosuit the aggregate type and spread rate desired.

Suitable Aggregates Types & Sizesa) Dry graded aggregate, within the following size -

Minimum size - 3mm (1/8”)Maximum size - 32mm (1 ¼”)The feedgates must be set to suit the aggregate size.

b) Bitumen pre-coated aggregate as graded sizes as above.Set feedgates to suit the aggregate size and engage theagitator shaft (see section 1.3.7).

ImportantThe pre-coated aggregate should be pre-made andhave ‘weathered’ to allow the bitumen to fully cure.This should take place before the seasons work starts,but not allow the stockpile to over-winter.If used during particularly hot weather, sprinklingwith water should be carried out to cool the pre-coatand so prevent lumps forming.

c) Graded aggregate, of non-uniform shape, up to 32mmmaximum size.The feedgates must be set to suit the largest dimension ofthe material.

d) Crushed rock up to 32mm maximum size.The feedgate must be set to suit the largest size stone.

e) Sand and fines Size 6mm to dustSpread to blind-off a surface after a light bitumen spray.It must be kept perfectly dry and free of moisture toprevent clogging. The agitators must be engaged (seesection 1.3.7.Set the feedgate gap to not less than 8mm setting andslow feedroller speed to obtain specified application rates.As the natural heaping angle of sand is less that normalfree flowing aggregate it will not flow to the full width ofthe extension spreading hoppers. A reduction in themaximum spread width possible will occur.



f) Heated Aggregate, dried & heated to a temperature of120°C maximum. Note that temperatures over 80°C willrequire the use of High Temperature conveyor belts(consult Phoenix).

NOTES: 1) Aggregate that contains a large volume of oversize material

can cause jamming between the feedrollers and feedgates.A greater feedgate setting will be required to allow it topass through without jams occurring.

2) The mechanism that prevents the extension feedrollers

from spreading aggregate direct behind the centre sectionfeedroller, when partly extended, may need to be adjustedto suit varying aggregate sizes

3) Grids in the top of the front spreading hopper have bars at

50mm spacing with a gap of approximately 40mm. Theseshould catch large lumps of aggregate or debris carriedonto the machine. These grids should be checked andcleared of collected material regularly.

HAZARD WARNING:Neither the centre or extension hopper grids should beremoved from the machine, unless for maintenance.Always ensure they are replaced after maintenance.

4) Aggregate coated in a hydrocarbon mixture, such as diesel

or kerosene will, after a prolonged period, affect theconveyor belts and other rubbers on the machine. Therubbers will deteriorate with the fabric and rubber de-bonding. Alternative conveyor belts, which can resist thesecompounds, can be supplied.

5) Contact Phoenix should you wish to spread materials ofdifferent sizes not covered above.

HAZARD WARNINGWith specialist materials or processes always haveavailable the Health & Safety information on thehandling, action in event of accident and personnelprotection equipment required for their use.



1.3.4 Rear Receiving Hopper & Tow Hook

Tow HookThe tow hook is used to attach the tipping truck to the ‘SPC10e’whilst the aggregate is being transferred into the rear receivinghopper. It allows for the tipping truck to be towed in reverse asthe transfer is taking place. A special towing bar must be fittedto the tipping truck for the tow hook to attach to.

The tow hook itself is connected to the machine’s structure by aflexible support unit that allows it to ‘float’ freely in order tovary with the truck tow bar height and to allow the truck to goaround bends (articulate) with the truck still connected, withoutdamage to either. [See fig SE902-13]

The tow hook will automatically engage the tipping truck once itis manoeuvred into position. It will continue to be held until the‘SPC10e’ operator triggers the release mechanism. A switch inthe joystick opens the tow hook to release the truck.

When PUSHED for 4 to 5 seconds the switch will OPEN the towhook to release the coupled truck. The tow hook remains in itsOPEN position ready to connect with the next truck.

Warning lights in the front console will illuminate to indicate thecurrent tow hook condition, as follows –

A GREEN light, with the ‘H’ legend, shows when thetow hook is open and ready to couple with a the truck.

A RED light, with a tipper truck in the raised position,shows when the truck is coupled and the tow hooklocked.

IMPORTANTThe lock bar must be removed from under the towhook before coupling to a truck.

Check the GREEN light is illuminated before allowinga truck to couple.

The engine must be running at 1800rpm for the towhook release to operate correctly.



Tow Hook Assembly



The tow hook may not fully open to release the tipping truck ifthe full weight of the truck is imposed on the tow hook.

Operating Tipa) Always take the weight of the truck on the tow hook

by gently moving forward to make sure the towhook has fully closed and locked, before the tipperbody begins to rise.

b) When releasing the tipping truck from the ‘SPC10e’,slow down enough to allow the tipping truck toclose slightly with the rear receiving hopper andtake the full weight off the tow hook. Once releasedyou can go back to the original speed.

HAZARD WARNINGIMMEDIATELY before releasing the truck by opening thetow hook, the operator MUST WARN the truck driver thatthey are to be released. This ensures that the truck drivertakes full control of their vehicle.

When the tow hook is not required and particularly whentravelling at HIGH range speeds, the tow hook MUST berestrained or it will strike the rear hopper structure. Place thelock bar at the rear under the tow hook; this requires it to belifted by hand. Release the lock bar by moving from it under thetow hook to a side position to allow the tow hook to fully float inuse.

All tipping trucks that will be used to supply aggregate to the‘SPC10e ’ will require the fitting of a specific tow bar across therear of these trucks. See section 3 for details of this tow bar,position and size.



Rear Receiving Hopper Assembly



Rear Receiving HopperThe rear receiving hopper is designed to receive, store and thenfunnel the aggregate onto the two conveyor belts. To assist this,the folding sides allow a wide opening when filling withaggregate (from the tipping truck) and can then fold-in to movethe aggregate onto the belts. This effectively empties the rearhopper and ensures all the aggregate held can be transferred tothe Front Hopper. [See fig. SE902-13]

Rubbers around the rear receiving hopper assist in containingthe aggregate, preventing it from spilling out, and closing off thegaps around the tipping truck body.

Operating Tip –Allow the aggregate to partly empty from the rearreceiving hopper before raising the folding sides. Thisprevents spillage from over the rear rubber skirts.

The folding sides are raised & lowered by a switch on the side ofthe Joystick. One side may move before the other due todifferent amounts of aggregate affecting them.

HAZARD WARNING

STOP personnel from being at the rear of the machinewhen connecting to the tipper truck. They are at riskof being struck by moving vehicles.

DO NOT over raise the truck’s tipping body whilst stillfull. A large weight of aggregate held high up leads toa high centre of gravity and the possible toppling overof the truck. It also places unnecessary strain on therear of the machine, which could cause suddenfailures to occur.

DO NOT allow the truck tailgate to rest on the floor ofthe rear receiving hopper. In certain cases the tailgatewill jam and if the tipping body continues to rise canlift the rear of the truck partly off the ground. Thiswill lead to a very dangerous situation where controlover the tipping truck can be lost and the rear of theSelf Propelled Chipping Spreader can overload, whichcan lead to possible sudden failure.

Always have the folding sides down before connectingto the tipping truck and do not raise them whilst the



tipping truck is attached, or serious damage canoccur.

ALWAYS lower the tipping truck’s body whenapproaching power lines or other low height obstaclessuch as bridges. Stop immediately if the body is stillraised.

ALWAYS lower the tipping truck body completelybefore releasing from tow hook. The body and tailgatecan become jammed into the rear receiving hopperand continue to tow the truck.

Be aware of the overall machine width at the rear,when the folding sides are their down position.

NEVER climb into the rear receiving hopper when inuse. You can be carried away by the conveyor belts orstruck by the folding sides when folding in.

NEVER travel at speeds above 10 kph (6 mph) withthe rear receiving hopper filled or the folding sides inthe lowered position.

When the tipping truck is coupled to the tow hook its reartailgate should be released so that the aggregate immediatelystarts to fill the rear receiving hopper.

IMPORTANTTo eliminate the need for a second person being at therear of the ‘SPC10e’ it is required that remotelyoperated, power released, truck tailgates on thetipping bodies are used.

If the passing width is restricted, fill the frontspreading hopper and part fill the rear receivinghopper so that the folding sides can be raised to avoidany obstruction.

The engine speed must be 1800rpm for the rearhopper sides to OPEN/CLOSE correctly.

The Joystick control switches for the rear hoppersides will NOT work when the transmission is in HIGHspeed range.



1.3.5 Conveyor Operation

Both conveyor belts can be operated as follows by controls in theRH console –

Main OFF/ON of RH & LH conveyors.

Control the rate at which the aggregate is transferredinto the front hopper by regulating the speed of eachconveyor individually.

Automatic ON/OFF (without operator intervention) iscontrolled by level sensors in the top of the fronthopper. This function allows the operator toconcentrate on the spreading operation whilstensuring the front hopper does not overfill.

Conveyor Controls



The conveyor controller has a master ON/OFF lever to start andstop the conveyors at any time. Individual speed controladjusters increase/decrease conveyor speeds. A separateAUTO/MAN switch allows for semi-automatic operation.

The lever of the conveyor controller should be UP when OFF andDOWN for ON. The left hand and right hand graduated knobscan be rotated to higher numbers to increase conveyor beltspeeds individually. The main conveyor ON/OFF can be operatedmanually as required to START/STOP both conveyors together.

Manual OperationIn MAN mode the conveyor will run, at the pre-set speed,until the controller lever is put in the OFF position. Theoperator should monitor the volume of aggregate held inthe front hopper frequently so that it neither over fills orruns too low.

Automatic OperationIn AUTO when the aggregate heap pushes the float leveloutward, either side, the conveyor automatically stops. Assoon as the level float is again vertical the conveyors willswitch ON themselves to refill the front hopper. Putting thecontroller lever into the OFF position stops the conveyorsimmediately.

Conveyor Belt Speed ControlIn both MAN & AUTO modes the speed of each conveyor canbe adjusted.

Operating Tips –Set the conveyor speed so that the front spreadinghopper fills at a rate slightly greater than theaggregate is being spread. This means the conveyorswill run almost continuously rather than withfrequent stops and starts.

The type of aggregate being spread may fill and heaponto the conveyor belt, differently. If the belt is veryfull a slow conveyor belt speed may be required toprevent loss of aggregate from the sides.

If you are only spreading on one side of the spreadingwidth, do not start the conveyor on the opposite sideand unnecessarily fill that side of the front spreadinghopper.



1.3.6 Setting-Up for Spreading

Firstly, assess the site conditions and ensure the ‘SPC10e’ canbe used safely. Carryout the following checks -

Check the site terrain is suitable, particularly whentowing the tipping truck. Check the gradient and forsharp bends where towing would be hazardous.

Check for overhead obstructions where the machinesown height or the tipping trucks height could cause acollision.

Check for obstructions that are sticking out from theroadside.

Assess the width of the road, whether it can becovered in one or more passes. Check whether ‘on themove’ width changes will be required. Decide on theplacing across the width of any longitudinal joint.

Assess whether, if there is normal traffic on the road,it will have space to pass. Assess what traffic controlwill be needed.

Assess the speed at which you can spread on theroad, given the conditions, the supply of aggregateavailable and the amount of width variation required.

HAZARD WARNING:Any safety concern must be resolved BEFORE usingthe machine and starting to work.

Before commencing spreading with the ‘SPC10e’ it is necessaryto set-up the machine’s aggregate handling and spreadingsystem for -

the type and size of aggregatethe application ratethe width of application

Ensure the front and rear hoppers are clear of any previousaggregate types before filling.



a. Set-Up of Rear Receiving Hopper & Conveyor BeltsOpen the rear receiving hopper folding sides ready to load.Release the lock bar to allow the tow hook to fully ‘float’.Select each conveyor belt to AUTO or MAN and set anappropriate conveyor belt speed.

b. Set-Up the spreading system for the aggregate size, typeand application rateIf possible, test to check the application rate andtransverse distribution. Adjust the feedgate gap andfeedroller speed proportion as necessary.

c. Set-Up for Width of SpreadAssess the road width to be spread. If greater than the fullspreading width, decide the widths that could be spreadduring each spreading pass.

Place the sight rods into their extension hopper holdersand lower into their forward position.

Pre-select which feedrollers are to be used, with theirindividual switches. (Note; they will not start to turn untilthe ‘Master’ ON/OFF switch on the joystick is switched ONand the joystick moved forward off the neutral position).

Set the DELAY function on the digital meter to ON.

Select the width of the centre spreading hopper byswitching OPEN/SHUT the cut-off blades. If full width isrequired, switch all to OPEN. This will require thecompressor to be running. The cut-off-blades will thenOPEN if switched.

Move the extension hoppers out (extend) until they matchthe actual road width. This may be done, by lining themachine up on the road and moving out the extensionhoppers until the required width is fully covered.

d. Additional Set-Up FeaturesIf spreading on bends in the road, set down the adapterscatter plates on the centre spreading hopper.

Engage the agitator shafts should the type of aggregaterequire their use. (If optionally fitted)



1.3.7 Spreading Hopper Agitators - OPTIONAL

The agitators are fitted only for use with specific types ofaggregates (see section 1.3.3.) and are omitted if these types arenot to be spread with the machine.

The front spreading hopper is fitted with agitator shafts; on inthe centre hopper and on each in the extension hoppers; toassist in the flow of sticky and poorly flowing aggregates.

The agitators will turn whenever the feedrollers are in operation;but may be dis-engaged when spreading dry aggregate. Theagitator ‘teeth/discs’ will wear away when in use; so if notrequired with the aggregate being spread they should be dis-engaged.

HAZARD WARNINGNEVER reach inside extension hoppers when theagitators are engaged and the feedrollers operating.Entanglement and sever injury can be caused.

To Engage the Centre Hopper Agitator ShaftThe centre hopper agitator shaft is driven by the chain that alsodrives the feedroller. The agitator may be ‘idled’, so that thedrive does not pass through to the shaft.

Three bolts (Allen headed screws, size 8mm AF)connect the drive sprocket to the shaft. Remove thethree bolts and the drive is dis-engaged. (Store thebolts in the toolbox).

View on RH End Centre Hopper End



To Engage the Extension Hopper Agitator ShaftsThe extension hopper agitator shafts are powered by their ownhydraulic motors linked to the feedroller on each side. Whenengaged, the agitators will operate at the same time as thefeedroller. The agitators may be ‘idled’, by dis-engaging thehydraulic motor using the hydraulic valve attached it.

The hydraulic control valve is manually set to engageor dis-engage the agitator drive.

To set the control valve it is necessary to reach inunder the inside of the extension hopper. It isrecommended that the extension be partly OUT to gainaccess.

HAZARD WARNINGBefore getting under the machine, switch OFF theengine and remove the ignition keys so it cannot berestarted.

Set the control lever in the DOWN position to idle theagitator shaft.

Set the control lever FWD or BACK to engage theagitator. (The agitator will rotate in either directiondepending on the lever setting FWD or BACK).

1.3.8 Spreading Aggregate

Before starting to work the ‘SPC10e ’ Self Propelled MeteringChipping Spreader, the set-up procedure (section 1.3.6) must becompleted and the machine ready to operate.

HAZARD WARNINGThe operator must remain at the operator’s positionwhilst the machine is in operation.

To fill the ‘SPC10e’a. Start the engine, increase the engine speed to 1800rpm,

and open the folding sides of the rear receiving hopper.b. Couple the tipping truck to the tow hook.c. Unlatch the tailgate on the tipping truck and begin to raise

its body.d. Start one or both conveyor belts and start to transfer the

aggregate to the front spreading hopper. Adjust theconveyor speed as necessary.

e. Fill the front spreading hopper and stop the conveyors, if inMAN mode; otherwise they will stop automatically.

f. Set the distance totaliser on the Digital Meter to zero.

To Use the ‘SPC10e’ to Spread Aggregateg. Move the machine forward until it is in position on the road

width to be covered.h. Select the LOW speed range.i. Ensure the engine speed is set to 1800rpm.j. Once the bitumen distributor has started, move forward

and build up to the spreading speed.k. At the start line of the new bitumen, use the Master

Feedroller Switch on the joystick to switch all pre-selectedfeedrollers ON together.

l. As the machine covers the new bitumen layer withaggregate, adjust the width of spread as necessary. Adjustthe application rate with the feedroller speed proportioncontrol, should it be required.

m. Unhitch the tipping truck once its aggregate has all beentransferred into the rear receiving hopper, after its bodyhas been fully lowered.

n. As the rear receiving hopper empties, raise the foldingsides to get all the aggregate onto the conveyor belts.



To Stop Spreadingo. As the front hopper passes over the line where the bitumen

stops, PRESS the Master Feedroller Switch to stop thefeedrollers, leaving enough time for the extension hoppersto also pass over the bitumen end line.

p. Slow the machine and bring to a stop. Record the totaldistance displayed on the Digital Meter.

q. Move the machine back to allow the bitumen distributor toreverse onto the joint line.

r. Retract the extension spreading hopper and close the rearreceiving hopper folding sides, if work completed.

Operating Tips –Drive the machine smoothly during operation. Do notmake sudden changes of speed, jerky movements orbrake violently as this can affect the evenness of theaggregate layer.

If the machine has to stop before the end of thebitumen layer, slow the machine before stoppingspreading so that the front tyres do not roll onto thebitumen layer, before coming to a halt.

Adjust the machine’s ground speed to match thebitumen distributor, as far as possible, keeping aconstant gap between the bitumen distributor and‘SPC10e’

Start & stop the feedrollers once the machine ismoving. It is not recommended to switch ON theMaster Switch with the machine stationary and startto move whilst spreading; likewise do not come to astop whilst still spreading.

Stop the machine before the last of the aggregate isused, as the machine will not run out the aggregate atthe same time across the full spread width.

When finishing at a site, try to run out the aggregatecarried by the ‘SPC10e’ on the last spreading run andfinish with a minimum left in the hoppers.



HAZARD WARNINGDO NOT drive the machine above 10 kph (6mph) witheither the front spreading hopper or rear receivinghopper filled with aggregate.

DO NOT drive the machine between sites with theextension spreading hoppers out or the rear receivinghopper sides down.

1.3.9 Test & Calibration of the Spreading System

Both the application rate and transverse distribution can betested to ensure the ‘SPC10e’ is correctly set-up for theparticular aggregate being spread.

The procedure to test the output is done by collecting a givenarea of the aggregate from that spread onto the road surface.Further, by duplicating this test at different places across thefull width of application, both the longitudinal and thetransverse application rate can be checked.

The application rate may be expressed in volume (litres persquare metre) or weight (kilograms per square metre). The testresults are most easily collected by weight measurements.

The weight collected may be converted to a volume dividing bythe aggregate’s density (weight per unit volume).

It is not required to have a bitumen layer sprayed in front of the‘SPC10e’ before spreading aggregate into the trays

Recommended Test Procedure – Transverse DistributionThe following procedure requires the use of collecting trays ofknown area; use a size of 25cm x 25cm to 50cm to 50cm and 2to 3cm high. A method of weighing the contents collected in thetray (probably including the tray) is also required. A scale isrecommended; the accuracy of measure should at least 1%.

a. Set-up the ‘SPC10e’, for the aggregate type andapplication rate as previously described.

b. Fill and prepare to spread over the maximum width thatwill be required. Full application width is recommended.

c. Set the three trays into position, firstly for testing thetransverse accuracy. These should be set inline acrossthe machine’s intended path, across the full width, butmissing the wheel path. Typically one tray to measureeach hoppers output.

d. Start the machine and reach the average spreadingspeed before passing over the trays in a straight line.Commence spreading before the trays are reached andspread until they are fully past over.

e. Collect each tray and in turn weight the contentscollected.



Spreading Calibration Test

Dia. SB109-05



Check the amount collected in each tray against the requiredamount. Also check that all trays have collected the same withinthe required tolerance.

Adjust the spreading system to obtain the correct amount acrossthe full application width. Should one tray be higher or lower,the feedgate in the corresponding hopper should be altered toincrease or decrease accordingly. Should the overall applicationbe too high or low, either adjust all feedgates by the sameamount or adjust the proportional speed of the feedrollers.

A number of test runs may be required to ensure that theapplication rate is set within the accuracy limits required.

Recommended Test Procedure – Longitudinal DistributionThe procedure for testing the longitudinal distribution uses thesame collecting trays and the measuring scales used above.

a. Leave the ‘SPC10e’ set-up for the transversedistribution, described above. The centre spreadinghopper only should be used at this stage.

b. Set the three trays into position so that each is in a linealong the road surface, along the direction of travel.

c. Start the machine and reach the average spreadingspeed before passing over the trays in a straight line.Commence spreading before the trays are reached andspread until they are all fully passed over.

d. Collect each tray and in turn weight the contentscollected.

The amount collected in the tray should represent the amountrequired and each tray should collect the same amount withinthe required tolerance.

The ground speed of the machine should be set at the normalspreading speed to be used. Ground speed can be varied duringthe test to establish the amount of variation that can betolerated whilst remaining inside the accuracy limits.

Within a reasonable tolerance it is not anticipated that theamounts collected in each will vary. However, should a variationbe found, check that the spreading system is set-up inaccordance with these instructions. Otherwise, read themaintenance procedures for the Front Spreading Hopper.
