Electric wire rope hoists are compact, lightweight, small in size, have highly interchangeable parts, and are easy to operate. When installing or reassembling Electric wire rope hoist a no-load run should be performed first. But ensure that the components are installed and not energized. In addition, a static load test should be performed under 125% of the rated load for about 10 minutes before normal use, lifting it about 100mm off the ground to check for normality. The dynamic load test is a repeated lifting and lateral movement test under the rated load weight. After the test, check whether the mechanical transmission part, electrical part, and connection part are normal and reliable. Or during use, it is forbidden to use it in an unsuitable environment, exceeding the rated load and the rated number of switch closures per hour (120 times). Next, pay attention to
When the electric wire rope hoist is running, it should also be noted that it is not allowed to press two hand-held buttons that make the electric hoist move in opposite directions at the same time.

After a period of time, the motor can be used again after cooling.
The above article content is an introduction to the precautions for using electric wire rope hoists. If you didn't understand it before, you can take a look now. Next issue, we will tell you more about it. Remember to watch it.
