Electric hoist is a commonly used lifting machinery tool, suitable for various lifting operations, relying on electric drive to achieve heavy lifting operations. Actually, electric hoists do not belong to special equipment.

Crane machinery is a mechanical and electrical equipment used for vertical lifting or vertical lifting and horizontal movement of heavy objects, with a range specified for elevators with a rated lifting capacity greater than or equal to 0.5t. A tower crane with a rated lifting capacity greater than or equal to 3 tons (or a rated lifting torque greater than or equal to 40 tons · m, or a loading and unloading bridge with a production rate greater than or equal to 300 tons/h) and a lifting height greater than or equal to 2 meters; Mechanical parking equipment with 2 or more floors. The lifting capacity of the structural components is generally 0.3-80 tons, and the lifting height is 3-30 meters.

Composed of an electric motor, transmission mechanism, and drum or sprocket, it is divided into two types: wire rope electric hoist and loop chain electric hoist. The wire rope electric hoist is divided into single speed lifting and dual speed lifting; Micro electric hoist, winch, multifunctional hoist. Reducer, lifting motor, running motor, flame arrester, cable sliding wire, drum device, hook device, coupling, flexible cable current inlet, etc. integrate power and braking force.

Whether an electric hoist is a special equipment depends on the tonnage of the electric hoist used. Electric hoist is a commonly used lifting machinery with fast lifting speed, large carrying capacity, and the ability to quickly complete heavy lifting operations.
