A fast and sure installation, a newsystem of interlocking and selfadjustable couplings, without bolts.
GRP Trays and Ladders areextremely robust andconsiderably lighter thanaluminium or steel. They have excellent firecharacteristics and a verylong life span. GRP systemshave a large cable capacity,and offer fast and flexibleinstallation solutions, withthe possibility of on-siteassembly and configuration.
TRAYS
Trays are assembled withinterlocking and self-adjustable couplings thatallow very rapid connection,no screws are required andthere are no sharp edges tocause problems. Tray systems provideexcellent cable protectionand the extensive range ofmoulded fittings includes:• Internal and External
Bends.• Flat Angles and Tees.• Offsets.• Reducers.

GRP Systems do not need tobe earthed and they do notexperience electrolyticcorrosion. Insulatingmaterials are non-conductive and resistant totemperatures from -80º to+130º. Systems do notrequire protective coatings,helping to contribute to lowmaintenance costs.GRP Cable trays and fittingsare pressed from glassreinforced polyester resin,using hot mouldingtechnology and facilitatingthe creation of smoothintricate shapes.GRP Ladder is manufacturedby Pultrusion, a processusing layers of mats androvings impregnated withresin and pulled through adie in a continuousoperation.

PRESSED TRUNKING/TRAYThe hot press moulded technique based oncomposite materials permits the forming of both3000mm base/lids and a large range of fittingswith various bend radius controls.
INSTALLATIONAll bases come with built-in self- adjustinginterlocking coupler, no fasteners required andthey position themselves automatically in anoptimal way in order to give an expansion joint forthermal movement.Support the base at 1500mm centres with 300mmof the base projecting male beyond the support.Place the projecting lip of the next base intoprevious base maintaining joint for expansion.
To position couplings without screwing junctions
Every junction/fitting should have anaccompanying support within 200mm.All bases and fittings must be fixed laterally with4mm clearance holes on each side of the support.
COVERSThese should be misalign with the base joint by atleast 300mm to ensure maximum strength andsecured to the base by means of four clips, tworequired at 50 – 100mm from each end.
LOADING CHARACTERISTICSDefection <5mm (1/300).Coefficient of safety > 1.7 (in accordance withIEC61537) using the interlocking and selfadjustable coupling without fasteners.

GRP (Glass Reinforced Polyester) is chosenfor its mechanical strength, lightness, ease ofinstallation and excellent resistance to fireand corrosion.
• 80% lighter than steel, 30% lighter thanaluminium.
• Rapid mounting and interlocking assembly.• On-site modification without the need for special
tools, no burring, no finishing, no danger ofinjury.
• Developed to withstand extreme weatherconditions, salt water and most chemicals.
• Very good stability to UV.• Insulating material, non-conductive, resistant to
temperatures from –80 to +130°C.• Excellent fire behaviour and self-extinguishing,
GRP does not conduct heat and has zero halogenin the case of fire.
• Resistant to corrosion and contributes to lowmaintenance costs.

CUTTING/FABRICATION ON SITEGRP can be cut and drilled with standard hand orpower tools. The absence of sharp edges afterfabrication makes these products safe for bothcables and the installation personnel.When cutting by hand it is recommended that atungsten carbide tipped heavy duty type cross-cutsaw be used. Power disc cutting equipment will easily andeffortlessly make this task quicker. Care andattention to compliance of Health and Safety atWork must be observed. Cutting by power toolsshould be done in an open air environment.

INSTALLATION
1. Place the end of the ladder about L/5 away fromthe supporting bracket.
L/5 corresponds to the ideal place for mechanicalstability: place the junction between 2 ladders atthis point.
2. Connect the ladders together.
30mm

L/5L
Place the side-rails facing each other.
Fix the stainless steel splice plates UL IH with thehelp of clip stalls, the oval holes* placed near thesupporting bracket.
Lock the junction with 4 x M620/V4AS bolts.
(*) The splice plates UL IH are pre-punched with 2holes Ø 8mm and 2 oval holes 20 x 8mm in order toassure a solid fixing and to allow the expansion ofthe GRP material.
3. Fix the ladder at each support with 2 hold-downclamps UL KS and 2 M1030/V4A bolts
4. Respect the rules of installation.
A. All fitings must be supported at every cableentry.
B. Add a central support for all fittings with radiusgreater than 250mm and/or with width greaterthan 400mm.
C. Lock systematically each splice plate UL IH with4 M620/V4AS bolts on fittings extremities.
5. Fix the cover with clips made of stainless steel316 (ref.DF50, DF80, DF100 and DF150).
Under normal conditions use 3 clips alternativelyon each side per 3 metres of ladders.Under extreme conditions (strong winds > 60km/h)use 7 clips per 3 metres of ladders.

LOAD CHARACTERISTICSCoefficient of safety > 1.7 (in accordance with IEC61537) this data is given for ladders coupled with spliceplates and bolts.
The deflection values are measured with the position of the junction between 2 ladders at a distance L/5from a support. If this distance is not respected, it is necessary to raise the deflection values by about30% when fully loaded.
Optimal conditions, for cost reduction on your installation.
Series UL53 and UL80 load diagram: supporting distances from 2 to 5m.
For 100 and 150 wall height refer to Marshall-Tufflex.
LOCALISED LOADSTo be able to compare this to a uniformly distributed load it is necessary to double the value of the localised load.Example: A 60kg local load at the centre of a ladder with 3m of support distance. Equivalent load: 60 x 2 = 120kg uniformly distributed along 3m (ie 40kg/m).
