Why can't ordinary chain hoist work continuously for a long time

Chain hoist is a lifting tool often used in workshops and workshops. Because of its unique advantages such as small size, light weight and easy operation, its market share is gradually increasing. Chain hoists are divided into ordinary economical and high-quality, ordinary ring Chain hoists generally cannot operate continuously for a long time. Why?

     When the chain hoist is working, the motor will continue to rotate, and a certain amount of heat will be generated at this time. If the heat is not dissipated in time, the motor will become hot, so we have to let the chain hoist work for a period of time and rest a while. In addition, in order to ensure that the heat generated by the chain hoist can be fully dissipated, we must ensure that the chain hoist fan is in good condition, and the fan position cannot be covered by anything when it is working.

      At the same time, the chain hoist working continuously will not only make the motor hot, but many parts will be reduced due to long-term use of lubricating oil, so that there will be abrasion between the parts, so when we are resting in the middle, we can apply some in the middle of the parts. Lubricating oil, which not only protects the parts, but also makes the work smoother.
