Explosion-proof hoist can't change accessories at will. Explosion-proof hoists are divided into electric hoists and chain block, and electric hoists are divided into wire rope electric hoists and electric chain hoist. Some parts of explosion-proof electric hoist are different from ordinary electric hoist, and are made of copper alloy. Therefore, if the chain block of explosion-proof electric hoist is broken, the accessories cannot be replaced at will. When the electric hoist can't work normally, it is necessary to cut off the power and stop working, so that professional maintenance personnel can carry out maintenance. When explosion-proof electric hoist is used, the specifications are distinguished according to tonnage and explosion-proof grade, and the power supply is mostly 380 volts.
