Safety elements of explosion-proof hand hoist are as follows:


1, explosion-proof hand hoist lifting chain should be suspended vertically, there shall be no wrong twist of the chain, the lower hook frame of the double chain shall not be overturned. The operator should stand in the same plane as the hand sprocket pull the hand chain, so that the hand sprocket along the clockwise rotation, the weight can rise; Reverse pull hand chain, can slowly descend. When lifting heavy objects, it is strictly prohibited to do any work or walk under them to avoid personal accidents.
