The traction rope of micro electric hoists is mostly steel wire rope, and the quality of the steel wire rope directly determines whether the micro electric hoist can continue to be used. So, how to determine whether the quality of the steel wire rope of the micro electric hoist is intact? Below, Guanhang will give you a brief understanding of the scrap conditions for the steel wire rope of micro electric hoists.

① The issue of the degree of wear on steel wire ropes can lead to a decrease in diameter, which naturally reduces their overall strength. Once the wear on the steel wire rope exceeds 40% of its diameter, it cannot be used anymore.

② If the entire strand of the wire rope of the micro electric hoist breaks or the core of the wire rope is squeezed out during use, causing structural damage, the wire rope should be scrapped.

③ Overloaded steel wire ropes shall not be continued to be used. When the appearance of the steel wire rope is severely deformed, the structure is damaged, the rope core is extruded, or there is obvious curling or stacking phenomenon, it should be scrapped.

④ When the number of broken wires in a steel wire rope reaches 7-8 within one pitch, it should be scrapped.

All of the above situations indicate that the steel wire rope of the micro electric hoist has been scrapped and cannot be used anymore. Therefore, when encountering such situations, it is necessary to stop using it and immediately replace it with a new one to avoid accidents.
