General Procedures
The following procedures are to be used as guidelines only. Specific installation methods will vary
somewhat depending on available equipment on site and each installer's preferences based on
experience.
Dimensional Reference Points
The path of each conveyor in the system is determined by establishing a reference point at each end.
The centerline of the conveyor is established and a chalk line is snapped between these points.
Conveyors should be installed with the centerline of the bed matching the centerline of the conveyor
path within 1/16" of true center. Locate and mark the center of the crossmembers at each end of the
conveyor. Use a plumb line or other applicable device to ensure accuracy to the chalk line.
Always carry out a thorough check for any obstructions such as building columns, manholes, etc. It may
be necessary to reroute the conveyor to avoid the obstruction. In this case it would be advisable to
begin installation at this point, using the obstruction as a reference point (Datum), and install the
sections in either direction as required.
All conveyor sections must be checked for squareness prior to installation as "racking" or being
knocked out of square may have occurred during shipping and handling.
•
Before restarting a conveyor which has been stopped because of an
emergency, an inspection of the conveyor must be made and the
cause of the stoppage determined. The starting device must be locked
out before any attempt is made to correct the cause of stoppage.
WARNING
•
The Installation Supervisor must be experienced with conveyor and
qualified in the mechanics of the equipment and enforce safe
working procedures for the protection of the crew, customer, and
customer's property.
