Double Roller Bushed Test Chain
Chain Position and Restraints
Chain position is critical to accurate scale calibration. To ensure proper position, please
account for the following:
• The pitch should be evenly divisible into the conveyor idler spacing.
• Rollers should straddle the idlers.
• Chain placement must be repeatable. Make sure that the chain extends a minimum
two rollers before and after the weighing mechanism.
The use of appropriate chain restraints will help control longitudinal stability and is
critical to ensure proper and safe usage. Restraints should do the following:
• Be attached to the chain at one end and fixed to posts mounted to each side of the
conveyor at about one belt width from the end of the chain.
• Form a “V” shape when viewed from above.
• Cross over and clear the belt edges by approximately one to two inches (2.5 to 5.0
cm).
Tension in the restraints should:
• Prevent chain movement along the belt
• Not lift the ends of the chain
Notes:
Turnbuckles are recommended to permit adequate adjustment of tension to
ensure the chain is fully extended and each roller is turning freely
