How to maintain the wire rope of electric hoist? What are the maintenance methods?

How to maintain the wire rope of electric hoist? Electric hoist is commonly used in industrial and mining enterprises, warehouses, wharves and other places. These electric hoists are frequently used, and the components of the electric hoist play an important role, so it is necessary for maintenance at ordinary times.

In order to prolong the service life of electric hoist wire rope, how should we maintain it?

First. The edge of the pulley used by the electric hoist shall be free of cracks and notches.

Second. When using steel wire rope on high-temperature objects, thermal insulation measures must be taken, because the strength of steel wire rope will be greatly reduced after being subjected to high temperature.

Third. The strength of the steel wire rope of the electric hoist must be checked frequently during use. Generally, a comprehensive inspection or strength test must be carried out at least six months.

Fourth. The steel wire rope shall not rub with other objects during the movement, nor shall it be dragged obliquely with the edge of the steel edge, so as to avoid cutting the steel wire rope by the edges and corners of the steel plate, which will directly affect the service life of the steel wire rope.

Fifth. During the use of the electric hoist, if the length is insufficient, the shackle must be used for connection. It is strictly prohibited to lengthen and lift the object by threading the steel wire rope through the steel wire rope head to avoid the resulting shear force.

Sixth. It is strictly prohibited to use overload during use, and shall not be subjected to impact force. When binding or lifting the required objects, pay attention not to make the steel wire rope directly contact with the sharp corners of the quick opening edges of the objects. Wood plates, canvas, gunny bags or other cushions shall be padded at their contacts to prevent the quick opening edges of the objects from damaging the steel wire rope and causing equipment and personal accidents.

Seventh. When storing the steel wire rope, clean the dirt on the steel wire rope according to the above method, apply lubricating oil, coil it, store it in a dry place, pad a wooden plate or sleeper under the steel wire rope, and conduct regular inspection.

Eighth. After the electric hoist has been used for a period of time, the steel wire rope must be lubricated. On the one hand, it can prevent the steel wire rope from rusting. On the other hand, during the use of the steel wire rope, the steel wire and steel wire in the same strand between each strand of the steel wire rope will have sliding friction with each other. Especially when the steel wire rope is subject to bending force, this friction is more exciting. After adding lubricating oil, this friction can be reduced.

Ninth. During the use of steel wire rope, pay special attention to prevent the steel wire rope from contacting with the welding wire. The steel wire rope will be damaged due to electric shock, which will affect the smooth operation.

Tenth. Pay attention to check whether there is any breakage or damage and whether it is used, or replace it with a new rope to ensure safety.
