In spite of careful converting and problem free installation of the conveyor and transmission belts it is possible that there are some difficulties. We help you to find the reason for it. We recommend possible measures for eliminating the problems to ensure an optimal running process.

Belt slips over the pulleys – heavy abrasions at the band edges

Problem / Measure	possible solutions
pulleys are adjusted insufficiently failure at the pulleys dirt stacking at the pulleys	pay attention to the exact parallelism of the pulleys, if necessary clean or change them
wrong cut belt edges faulty joining damaged belt	repair or change the belt
irregular absorption of humidity because of faulty storage	store the belt cool, dry and clean, protect it from dust and UV radiation
irregular loading of the belt	equal allocation of the loading
too low belt tension	raise the basic tension, tool up the pulleys convex

Joining opens

Problem / Measure	possible solutions
wrong or failure type of joining	choose the joining according to the application
tighten the belt too much	correct the belt tension
inadequate belt	adapt the belt quality to the application
belt speed is too high	correct the belt speed
pulley diameter is too small	use bigger pulleys or change the belt material
incorrect placed belt	pay attention to the correct rolling direction
dirt stacking at the pulleys	clean the pulleys regularly
too strong start-up	let the belt start-up slowly
belt is overheated due to too much slip	adapt the belt tension

Profiles separate from the belt or break

Problem / Measure	possible solutions
pulley diameter is too small	enlarge the pulleys or change the belt quality
profiles are beating or grinding	check the conveying machinery for a construction fault and if necessary change the type of profile
belt is running not straight	arrange the pulleys in a parallel
belt is overloaded	equal allocation of the loading
chemical aggressive operating conditions	adapt the quality of the belt and profiles
insufficiently profiles	adapt the profile to the application
faulty profile welding	repair or change the belt

Problem / Measure	possible solutions
insufficiently surfacing of the pulleys	coat the pulleys with roll surfacing
polluted running side / pulleys	clean the belt / pulleys
belt adhesion too high	change the belt quality
low drive	change the belt quality or raise the engine power
belt is too heavy	change the belt quality
too low belt tension	correct the belt tension

Belt slips over the pulleys – heavy abrasions at the band edges

Joining opens

Profiles separate from the belt or break

Slipping of the belt

High abrasion at the carrying or the running side

Transmission belt causes high operating noises or belt is vibrating

Problem / Measure	possible solutions
adverse operating conditions	adapt the belt quality
goods to be conveyed are not suitable	change the belt quality
blocked or nagged pulleys	repair the pulleys if necessary change them
dirt stacking at the pulleys	clean the pulleys regularly
wrong belt choice	change the belt quality

Problem / Measure	possible solutions
too low transmission belt tension	adapt tension to the type of transmission belt
