The wire rope hoist wire rope should be how to care for?
Q: wire rope hoist wire rope should be how to care for?
A: First, wire rope hoist wire rope maintenance:
Pulley, electric wire rope hoist worn its edges should not have broken down and the gap.
2, wire rope in the movement do not and other objects friction, more should not drag with the steel edge of the edge of the ramp, corners cut off the wire rope to prevent the steel plate, directly affect the service life of the wire rope.
3, the rope used in the high-temperature object, must be used insulation measures, because the rope its strength after subjected to high temperatures will be greatly reduced.
Electric hoist during use must always check the wire rope strength, generally at least six months must conduct a comprehensive inspection or do a strength test.
5, the use of the process of non-overload use should not be affected by the impact, strapping or lifting required material, wire rope to be careful not to make a direct contact and the objects fast mouth Prism acute angle relative to the contact pad woodblock , canvas, burlap or other padding material to prevent the objects fast the mouth corners damaged wire rope and equipment and life accidents.
Electric hoist during use, such as the length enough shackle connection must be used strictly prohibited slickline wire rope head wear then a long lifting objects, to avoid the resulting shear force.
7, after a period of use, the electric hoist, wire rope must add oil, on the one hand, you can prevent the wire rope rust, on the other hand, the rope in the process of using its per sub-rope between steel wire and steel wire in the same shares sliding friction with each other, especially when the wire rope by bending force, this friction is more incentive, after adding a lubricant can reduce this friction.
8 wire rope storage, according to the above method of wire rope on the dirt clean after Shanghao lubricating oil, and then coiled good store in a dry place, pad beneath the wire rope regularly checked to woodblock or sleepers.
9, wire rope during use, with particular attention to prevent contact with the wire rope and welding line. Due to touch the electric wire rope will be damaged, affecting the smooth progress of the job.
10, pay attention to check whether the fracture and whether the use of, or need to exchange a new rope to ensure safety.
Electric hoist wire ropes end-of-life criteria:
1, electric hoist wire rope wear, decreases in diameter, should scrap processing 40% more than the diameter of the wire rope.
2 whole dice rope breaking electric hoist wire rope in the process, often appear to wire rope or wire rope cord is squeezed out causing structural damage, then the wire rope should be scrapped.
Within one pitch off Sida 7-8 roots should be scrapped.
4, wire rope transport or hoisting metal solution, hot materials, acid, flammable and toxic objects, highly chemical media corrosion, wire rope should be scrapped.
5, overload the wire rope shall not continue to use, when the appearance of severely deformed wire rope, structural damage, rope the the core extrusion or have obvious kink, the heap poly phenomena for scrap processing.
