رافعة كهربائية بحبل سلكي 500 كجم - 20 طن

The strength of the wire rope electric hoist 500kg -20 ton must be checked frequently during use. Generally, a comprehensive inspection or strength test must be carried out at least six months. It is strictly forbidden to use overload during use, and it should not be subjected to impact force.

When bundling or hoisting objects, be careful not to make the wire rope directly contact the sharp edges of the objects. Use woodblocks, canvas, sacks, or other padding where they meet. In order to prevent the edge and corner of the object from damaging the wire rope and causing equipment and personal accidents.

If the length is not enough, a shackle connection must be used. It is strictly forbidden to use the wire rope head to wear the thin wire rope to lengthen the lifting object, so as to avoid the resulting shear force.

During the use of the wire rope electric hoist 500kg -20 ton, do not rub against other objects, nor should it be dragged obliquely with the edge of the steel edge. In order to avoid the edges and corners of the steel plate cutting the wire rope, it will directly affect the service life of the wire rope.

When using a wire rope on a high temperature object, heat insulation measures must be taken, because the strength of the wire rope will be greatly reduced after being subjected to high temperature.

After using for a period of time, it is necessary to add lubricating oil. On the one hand, it can prevent the wire rope from rusting, on the other hand, during the use of the wire rope, the steel wires between each of its sub-ropes will produce sliding friction with each other. Especially when the wire rope is subjected to bending force, this friction is more excited, and this friction can be reduced by adding lubricating oil.
