BELT BOWED – Avoid telescopic belt rolls or storing them in damp locations. *A new belt should straighten

BELT IMPROPERLY SPLICED OR WRONG FASTERNERS - Use correct fasteners. Retighten after running for a short while. If improperly spliced, remove belt splice and make new splice. *Set up regular inspection schedules.

BELT SPEED TO FAST – Reduce belt speed

BELT STRIANED ON ONE SIDE – Allow time for new belt to “break in”. If belt does not break in properly or is not new, remove strained section and splice in a new piece.

BREAKER STRIP MISSING OR INADUQUATE – When is lost, install belt with proper breaker strip.

COUNTERWEIGHT TO HEAVY – Recalculate weight require and adjust counterweight accordingly. * Reduce take-up tension to point of slip, then tighten slightly.

COUNTERWEIGHT TO LIGHT – Recalculate weight required and adjust counterweight or screw take-up accordingly.

DAMAGED BY:ABRASIVES, ACID, CHEMICALS, HEAT, MILDEW, OIL – Use belt designed for specific conditions

DIFFERENTIAL SPEED WRONG ON DUAL PULLEYS -Make necessary adjustment.*

DRIVE UNERBELTED – Recalculate maximum belt tensions and select correct belt. If line is over-extended, consider using two-flight system with transfer point. If carcass is not rigit enough for load, install belt with proper flexibility when service is lost.

EDGE WORN OR BROKEN – Repair belt edge. Remove badly worn ot out-of-square section and splice in a new piece.

EXCESSIVE IMPACT OF MATERIAL ON BELT OR FASTE – Use correctly designed chutes and baffles. Make vulcanized splices. Install loading idlers. Where material is trapped under skirts, adjust skirt boards to minimum clearance or install cushioning idlers to hold belt against skirts.

EXCESSIVE TENSION – Recalculate and adjust tension. Use vulcanized splice within recommended limits.

FROZEN IDLERS – Free idlers. Lubricate. Improve

IDLERS OR PULLEYS OUT OF SQUARE WITH CENTRE LINE OF CONVEYOR – Realign, Install limit

IDLERS IMPROPERLY PLACED – Relocate idler or insert additional idlers spaced to support belt.

IMPROPER LOADING, SPILLAGE – Feed should be direction of belt travel and at belt speed, centered on skirt boards.

IMPROPER STORAGE OR HANDLING – Refer to belting suppliers for storage and handling tips.

INSUFFICIANT TRACTION BETWEEN BELT &PULLEY – Increase wrap with snap pulleys. Lag drive pulley. In wet conditions, use grooved lagging. Installcorrect cleaning devices for safety. See item 7 on the next page.

MATERIAL BETWEEN BELT AND PULLEY – Use Skirt boards properly. Remove accumulation. Improve maintenance.

MATERIAL BUILD UP – Remove accumulation. Install cleaning devices, scrapers, and “V” decking. Improve housekeeping.

PULLEY LAGGING WORN – Replace worn pulley lagging. Use grooved lagging for wet conditions. Tighten loose and protruding bolts.

PULLEY TO SMALL – Use larger diameter pulleys

RADUIS OF CONVEX VERTICAL CURVE TOO SMALL – Increase radius by vertical realignment of Idlers to prevent excessive edge tension.

RELATIVE LOADING VELOCITY TOO HIGH OR TOO LOW – Adjust chutes or correct belt speed. Consider use of loading idlers.

SIDE LOADING – Load in direction of belt travel, In center of conveyor.

SKIRTS IMPROPERLY PLACED – Install skirt boards so that they do not rub against belt.
