Electric hoists are devices that lift, lower, and move heavy loads. They are commonly suspended from structures by hook or trolley mounts. Electric hoists are used in the transportation, construction, manufacturing, mining, and material handling industries, among others.

Electric hoists are powered by electricity to transfer motor-generated force across a series of gears which multiply the force into one that is large enough to lift the designated load. The load is usually lifted by a hook that is attached to a chain, rope, or wire. Electric power hoists are used for loads that need precise, smooth handling. They operate more quietly and require fewer adjustments during operation than air hoists, and electric power is typically more readily available than compressed air. Because they generate heat, electric hoists require cool-down periods between operations to protect the motor and gears. 

When selecting an electric power hoist, consider the load capacity and lift, according to the specific application. Load capacity is the weight a hoist can handle, expressed in pounds or tons. Lift is the maximum vertical distance the load hook can move a load, expressed in feet.
