A good safety program makes provisions for hazard identification, open lines ofcommunications, allocation of responsibilities, record keeping, training and, regular inspectionand program audits both internal and externally conducted.

Communication is the key to improving the effectiveness of safety programs. Post allregulations, safety reminders, results of safety audits, newly found hazards, etc. All personnelshould be encouraged to ask questions and to bring safety related matters to the attention ofeveryone.

All personnel need to be “Proactive” not “Reactive” when it comes to safety. Anticipate

possible accidents and continually review the workplace for possible hazards.All employees have accountability to themselves and their colleagues to achieve safetyexcellence. Safety needs to be an integral part of every employee's job and a working climateneeds to be developed where safety is highly valued by each and every employee.

Educating and training employees is mandatory to achieve safety excellence. In addition to theapplicable company, industry, provincial and federal regulations, the latest edition of thefollowing codes and standards are recommended for your safety training programmes andinformation/reference manuals:

INSTALLATION

INSTRUCTION MANUALMAN-E-HOODS-20

Rev. 11 Sept. 2002PAGE 9 OF 20

Pre-InstallationThis manual has been written around standard 4 foot Stephens-Adamson A-1 StyleHoods in Galvanized and Aluminum construction and A-1 Style 3/4 Coverage Hoodsin Galvanized construction. However, the instructions are just as appropriate for 5-foot hoods and almost all special hoods. If you require assistance for special hoodscontact Stephens-Adamson or your local Stephens-Adamson Distributor.

Stephens-Adamson Hoods are shipped unassembled. Using the drawings at the end

of this manual, check that you have received the proper quantity of bands, covers,

foot brackets, retaining bars, eyebolts and fasteners. Also check for any damage

that may have been caused in shipping.

Band Assembly

Assemble the foot brackets and retaining bar to thesupport bands. First bolt the foot brackets (Item 1) tothe bottom of each side of the support band (Item 2).Refer to the drawings on pages 14, 15 & 16 and thefigures on this page. Bolt the retaining bar (Item 6) tothe support band (Item 2) using the hole that is locatedat 45° around the curve in the band. Band assemblycan be done prior to mounting the assembled support

bands on the conveyor frame.


10/20

INSTALLATION



Band Installation On The ConveyorBolt the feet of the support bands to the stringer through the rear slots. As the

support bands are mounted on the conveyor frame, care must be taken to be sure

that they are all positioned so that the retaining bar is facing the main access side

of the conveyor i.e. towards the walkway or the maintenance aisle. It is necessary

that all the retaining bars are on the same and correct side as they are the means

for fastening the cover sections in the open position. Be sure that the support

bands are all in-line down the conveyor centerline before tightening the mounting

bolts.

Spacing Of Support Bands

Normal spacing of support bands is 4'- 0" centers. However, support band spacing

should match the idler spacing or interference with the idler frame feet will happen

after only a few spacings. When hoods are applied to conveyor frames without pre-

punched mounting holes, or to curved frames refer to concave and convex curve

sections for further instructions. Use of oversize hoods for greater clearance

requires use of adapter plates between foot bracket and conveyor frame stringers.

Concave Curves

Using standard belt conveyor hoods, concave curves can be obtained in two ways.

Installing the support bands on 4'- 0" centers as usual and taking up the built in

longitudinal clearance between hood and support bands, or if the radius required is

not met, by installing the support bands on up to 4'- 1" centers, thus increasing the

available clearance mentioned above. The following table indicates the

minimum radius obtained with support band centers varying from the standard 4'- 0"

to a maximum of 4'- 1" for the various nominal belt conveyor hood sizes. For

hoods at other than 4'-0" centers contact Stephens-Adamson or your local

Stephens-Adamson Conveyor Components Distributor.

SAFETY PRECAUTIONS IN USE


Safety Precautions In Use

When a cover section is opened, it should always be carefully raised to the retainingbar and fastened securely to it before performing any inspection or maintenancefunctions on the idlers. Check that the nuts and washers on the eyebolts are firmlyholding the eyebolts to the retaining bars. Never open a cover section in high winds.Personal injury and damage to the cover may occur. Never unfasten all four of theeyebolts of a hood section cover on both sides of the conveyor run without takingadequate precautions regarding the handling of the completely free cover section,particularly in windy conditions.

When a cover section is closed, it should always be securely fastened back to the footbrackets. Check that the nuts and washers on the eyebolts are firmly holding theeyebolts to the foot brackets. Also check that the eyebolts are providing enoughtension to keep the hood cover sections sealed tightly against the support bands.

STORAGE INSTRUCTIONS


Storage Instructions (Control of Wet Storage Stain)

At the time of shipment from the factory, Stephens-Adamson galvanized hoods are

free from moisture and stain. They may become wet in transit or storage due to

rain; condensation or other causes and develop “wet storage stain”. To help

control this problem, the following suggestions are offered.

Galvanized hoods provide excellent service life under normal weather conditions.

Time may darken them slightly, but the sheets will stil l present an attractive

appearance. However, galvanized sheets are subject to possible localized

discoloration or stain when the zinc coating is exposed to water trapped between

closely fitted surfaces. This can happen either in shipment or in storage, whenpiles of sheets or nested formed items become wet from rain, condensation or

other causes of moisture. This discoloration is known as "wet storage stain".

The stain is usually superficial, and has essentially no effect on the service life of

the galvanized sheets. If, however, the trapped moisture is permitted to remain on

the sheets, the attack may become severe, reducing the effective service life of

the sheet.

In view of the foregoing, and towards further controlling wet storage stain, we

recommend that purchasers should:

1. Inspect for moisture upon receipt. If present, dry the hoods at once.2. Where possible, store the hoods in a warm, dry place. Do not store

outdoors. Do not store covered with plastics.

3. When stored in warehouses or in the field prior to application, do notpermit moisture from the weather, from condensation or othersources to remain between the hoods. If conditions permit, stand theformed hoods on end on wood blocks, separating the sheets to allowmoisture to drain off and air to circulate.
