What's wrong with the often abnormalities in the use of electric hoist equipment

Our statistics have found that for a long time, based on feedback from different user groups and production and maintenance experience, we have found that even if the quality of the equipment is good, occasionally some small failures may occur during long-term use.

So what causes the abnormal noise of the electric hoist?

    The abnormal noise of the equipment during work is a problem that many people have encountered. This may be caused by equipment failure. For example, when there is a problem with the control electrical, motor or reducer, it will often be accompanied by noise. In addition, it will also be caused by poor lubrication. To cause this situation, we can judge the problem based on the location and sound of the abnormal noise.

    If the electric hoist equipment fails to stop normally during use, it may be caused by the contact of the contactor that cannot be disconnected. At this time, we need to immediately cut off the power supply and force the stop, and perform maintenance on the part in time, if necessary Also need to directly replace damaged parts. If the temperature of the equipment motor is found to rise abnormally, check whether there is an overload phenomenon. If there is no problem, further check whether the equipment motor bearing is damaged, whether the gap size is normal during operation, and operate according to the specified requirements. If fever is found, stop working in time, and adjust the system. The dynamic gap and working state can avoid heating due to friction and excessive current.

    In addition, if the electric hoist is out of service for a long time, the brake nut is adjusted incorrectly during maintenance, or the brake ring is greatly worn, the sliding distance during braking may exceed the specified requirements. At this time, readjust according to the instructions, and at the same time Do the cleaning work well, but adjustments are prohibited during operation. If it still cannot be solved, you need to consider checking or replacing the coupling.
