Group crane electric hoist is commonly used for construction work of engineering projects and building overall lifting scaffolding. It can also be used for loading and unloading of stone processing industry, road and bridge construction and equipment installation, which can greatly reduce labor intensity and improve production efficiency and safety. Group crane electric hoist has the characteristics of compact structure, small size, light weight, high efficiency, reliable braking and convenient use. Group crane electric hoist, also known as welding tank electric hoist, construction climbing frame electric hoist, DHP type electric hoist, is composed of HS type or HSZ type chain hoist, three-phase disc brake motor and planetary reducer. The transmission principle of the group hoist: the rotation of the motor is decelerated by the reducer, and the speed and power are output to make the lower hook of the chain hoist rise or fall. When the motor is broken, the lower hook of the hoist stops working by relying on the brake use of the brake motor, and the heavy object stops at the corresponding position.
