What should I do if the electric hoist wire rope breaks?

The wire rope fracture failure is mainly caused by the failure of the lifting limiter. When the load reaches the high or low limit position, it continues to rise and fall, causing the wire rope to break. If the overload is too large, that is, the lifting load exceeds the rated load that the wire rope can accept, and reaches the breaking force of the wire rope, and the knowledge-type wire rope breaks. In addition, when the wire rope meets the obsolescence standard and is still in use, the wire rope will break.

If there is any abnormal sound during the operation of the wire rope electric hoist, please pay attention to it immediately, check and protect it. The appearance of abnormal sound clarifies that the wire rope electric hoist presents some problems. If it is discovered in time, it can be protected in time.

In order to effectively prevent the wire rope from breaking, we must first consider these issues. However, in many cases, accidents caused by wire rope breakage are often unpredictable. Some are caused by wire rope breakage, and some are formed by long-term use, which causes the rope pressure plate to become loose and the wire rope to be pulled out of the drum. Therefore, we do not only rely on safety protection devices to ensure safety. In order to effectively prevent the recurrence of similar accidents, we must first consider the intrinsic safety of the equipment, select a steel wire rope with a satisfactory safety factor, and equip with limit switches, overload limiters and other safety protections. Device. Secondly, it is necessary to consider measures to prevent the wire rope from breaking or towing the rope causing the lifting weight to drop.
The direction of the abnormal sound is different, and the explanation of the problem is also different. If it occurs in the control circuit, the contactor is faulty. If the motor announces abnormal noise, immediately stop and check the single-phase operation of the motor or the bearing damage, the coupling shaft is incorrect, and the faults such as clearing the hole will cause the motor to have abnormal noise, sound direction, and different fault levels and sounds. The reducer announces abnormal noise. Reducer failure (such as gear box or bearing lack of lubricating oil, gear wear or damage, bearing damage, etc.) should be shut down for inspection.

The identification of abnormal sound of wire rope electric hoist requires professionals, as long as the professional can identify the abnormal sound in the early stage. Therefore, it is very important to find a professional with relevant operating experience. If abnormal sound is detected in time, safety accidents can be prevented. On the contrary, it may cause a certain safety accident, damage the wire rope electric hoist, and cause property losses.
