Working Duty Classification of Electric Hoist

An electric hoist is a type of lifting device that is powered by electricity. It is designed to lift and move heavy loads vertically or horizontally in various industrial and commercial settings. But do you know what does the meaning of electric hoist work duty mean?

Do you know what are the work duty of electric hoist? And what does they mean?

Meaning of Electric Hoist Working Level:

The working level of an electric hoist is based on its operational load and frequency of use. A higher working level is required if the hoist is frequently operated at full load. This means a greater workload for the motor, demanding better motor performance and sometimes requiring specialized motors. The working level of an electric hoist does not directly correspond to the working level of the motor. Higher working levels also impose higher requirements on electrical components, wire ropes, and other accessories.

Relationship between Working Level and Electric Hoist Working System:

The working level can be divided into different types of working systems, including continuous working system, short-time working system, intermittent periodic working system, including intermittent periodic working system with starting, including intermittent periodic working system with electric braking, continuous periodic working system, including continuous periodic working system with electric braking, including continuous periodic working system with variable speed and load, and non-periodic variations of load and speed working system.

In general, the higher the working level of an electric hoist, the greater the workload on the motor and the better the motor's performance.

The work duty for electric hoists include M3, M4, M5, M6, M7, and M8. The higher the level, the greater the workload on the motor, the better the motor's performance, and the longer the service life. The working wear level primarily reflects the operational load and frequency of use of the electric hoist.
