Why can't the electric chain hoist work continuously for a long time?

Electric chain hoist is a lifting tool often used in workshops, because of its unique advantages such as small size, light weight, and easy operation, the market share is gradually increasing. Hoists are divided into economical and high-quality, commercial chain hoists cannot operate continuously for a long time.

When the electric chain hoist is working, the motor will keep rotating and heat will be generated. If the heat is not dissipated in time, the motor maybe burnt, so if the chain hoist is working for a period of time, it is necessary to take a rest. In addition, in order to make the heat fully dissipated, it must ensure that the chain hoist is in good condition, the fan cannot be covered by anything when it is working.

The continuous operation not only make the motor hot, but many parts will lack of lubricating due to long-term use, so that there will be wear between the parts, during the rest in the middle, labricating oil can be added, which can not only protects the parts, but also makes the work smoothly.
