Working Duty Classifications for Electric Chain Hoist

• The working duty of the polipastos eléctricos de cadena is an internationally accepted value defined according to the working frequency and working time of the electric hoist under the rated load.
• With the same rated load and the same working frequency, the higher the working level, the longer the working time of the electric crane hoist, that is to say, the longer the service life of the polipastos eléctricos de cadena; the higher the working level of the same rated load, the higher the working time of the hoist.
• The more it can withstand high-frequency workloads. Therefore, in the uninterrupted working condition of the production workshop assembly line, choosing a high-level electric hoist will be the first choice.
• The working level of the electric hoist depends on the material and craftsmanship of the hoist hardware, which means that the working level of a hoist is determined from the moment the finished product on the production line is completed.
• The electric hoist working duty is basically M3 or M4. For each higher level of work, the same load and frequency of use in the same environment will double the life of the hoist.

Therefore, when buying an electric chain hoist, the working duty is an important parameter that must be considered. Combining the working conditions to choose the most applicable is the most economical, safest and wise choice!
