After a long time operation of bucket elevator, the chain, round head, tail wheel gear will appear a certain degree of wear. The drop side chain bucket without material belongs to the loose side, the rise side chain bucket filled with material belongs to tight edge, so the drop side has a larger range of swing amplitude than up side. Like bicycle chain, loose edge side has bigger swing.
Bucket elevating conveyor shaft pin on the chain link will appear a certain wear and lead to the chain in a certain degree of loose, in the process of hoist running, the chain will appear shaking and when it runs to the head wheel(tail wheel), occlusion abnormal with chains and gear wheels is easy to produce hitched noise.
Adjust tension bolt. The best way is install orbit at the head part to prevent chain swing. Non-return device to prevent bucket return.
