Bear chain hoists mainland Asia Machinery Industry Co., Ltd. for the production, mainly in the lifting industry use, so for the operation of chain hoists bear to pay attention to timely and correct operation specification, we give you the following detailed introduction. We must bear chain hoists for safety checks before lifting, which can effectively prevent unexpected situations. Then the opponent pull hoist for routine checks, such as chain hoists friction plate, if there is oil on the friction plate should be replaced in time, the opponent pull hoist machinery parts for routine maintenance. Chain hoists chain lubrication and maintenance have always been, first, to prevent rusting chain, which appeared card chain case, and secondly to extend the life of lifting chain. In operation, as long as the following points, we will be able to do the chain hoist operation. First, we followed each mechanical transmission parts must be intact and the lifting chain oiled air operating normally. The above description of the Formosan black bear is our chain hoists, and hope that we can understand some aspects of operational problems and timely carry out inspection work.
