A crane hoist is a component of a crane that is used to lift and move heavy loads vertically. A crane hoist typically consists of a hoist motor, a drum, and a cable or chain. The hoist motor is used to power the drum, that winds and unwinds the cable or chain. The cable or chain is attached to a hook or other lifting device, that is used to attach and lift the load.

Crane hoists come in a variety of types, including electric, hydraulic, and pneumatic. Electric crane hoists are the most common and are powered by an electric motor. Hydraulic crane hoists use a hydraulic motor to power the drum, while pneumatic crane hoists use compressed air to power the motor.

Crane hoists are typically used in construction, manufacturing, and logistics industries to lift and move heavy loads. They are designed to handle loads that are too heavy for humans to lift manually, making them an essential tool in many industrial operations.

In addition to the hoist motor, drum, and cable or chain, crane hoists may also include safety features such as overload protection, which prevents the hoist from lifting more than its rated capacity, and emergency stop buttons, which can be used to stop the hoist in case of an emergency.

Overall, a crane hoist is a critical component of a crane that is used to lift and move heavy loads vertically. With their ability to handle heavy loads safely and efficiently, crane hoists are an essential tool in many industrial operations.
