When you are using chain block, it is unavoidable to have wear and down. On the one hand, the working of the chain block may cause the wear and down. On the other way, wrong operations have damage to the chain hoist as well. What operations will increase the wear to increase the life of the chain hoist?
Overload will add the bearing load of manual chain hoist and make the machine pressure and friction larger, so that it will speed up the wear of parts.
The most serious wear is the chain and sprocket, so that the weight can not rise or fall, affecting normal use.
If you buy chain block from our factory，try not to violate regulations, reduce parts wear and prolong the life of hand hoist.
