It is mainly used for various lifting, pulling, loading and unloading of heavy objects, inverted welding of oil tanks, such as the installation and movement of various large and medium-sized concrete, steel structures and mechanical equipment. It is suitable for construction and installation companies, civil engineering projects of factories and mines, bridge construction, electricity, ships, automobile manufacturing, construction, roads, bridges, metallurgy, mining, slope tunnels, shaft management and protection and other basic construction projects. The existing wire rope electric hoist is mainly composed of a shell, a drum, a wire rope, a hook, a reducer and a lifting motor. The lifting motor is fixed on the shell, and the output shaft is connected to the reducer. The reducer can be used to adjust the speed of the output shaft of the lifting motor. When the drum is fixedly connected to the output shaft, the rotation of the lifting motor can drive the drum to rise and fall, so that the drum drives the wire rope fixedly connected to the drum to rise and fall, thereby realizing the lifting of the hook;
