Installation RECEIVING Immediately upon receipt all items in the conveyor or component shipment should be checked against shipping papers for shortages and inspected for damage. Items to be checked include bent or dented troughs, covers, flights, chain, guards, drives, etc. Note claims for damaged parts on shippers and immediately file a claim. DO NOT ATTEMPT TO INSTALL A DAMAGED ITEM OR CONVEYOR. LIFTING AND MOVING Extreme care must be taken to prevent damage when moving assembled conveyors or components.
Installation For shop assembled conveyors, units are match marked and shipped in longest sections practical for shipment. Field assembly can be accomplished by connecting marked joints and in accordance with packing list and or drawing if applicable. In field erection, the mounting surfaces for supporting the conveyor must be level and true so there is no distortion in the conveyor. Shims or Grout should be used when required.

In start-up of the conveyor, operate several hours empty as a break in period. Observe for bearing heat up, unusual noises or drive misalignment.
Problem Cause / Remedy Chart PROBLEM CAUSE REMEDY PREMATURE TROUGH FAILURE A) Gauge too light B) Worn flights C) Excessive chain speed A) Increase thickness. Consult catalog materials table / component series for recommendation. B) Replace flights C) Check speed A) Excessive heat A) Change flight material. ACCELERATED FLIGHT WEAR B) Speed too high UHMW limited to 175ºF B) Slow drag down. Consult catalog engineering section to determine proper speed.
