Wire rope pulling hoist wire rope maintenance and inspection

Have been painted in the manufacture of wire rope enough grease, but after running  lever hoist   grease will decrease gradually and the rope will occupy the surface of dust, debris and dirt, causing the wire rope and wire rope sheave wear and rust, so should be regularly cleaned and refueling. Easy way is to use a wire brush and other appropriate tools wipe rope surface dust and dirt, the surface of the heating and melting of the wire rope grease evenly on the surface, can also be put on the 30th or 40 engine oil pouring spout on a wire surface , but do not spray too much pollution.

Use rope must be checked regularly and make a record, regularly check the contents of the fuel in addition to the cleaning, we must also check the degree of wear of steel wire rope, wire break situation, the extent of corrosion as well as hooks, rings, round the lubrication grooves and other vulnerable parts wear. Abnormal situation must be timely adjustment or replacement.
wire rope winch wire rope inspection:
1, wire rope specifications, models should meet the design requirements, and pulleys, reels match and correctly reeved, wire rope should be firmly fixed, and reliable.

5, the rope should be oiled, and should not be rubbing metal structure
6, the rope should not be kinked, crushed, bent, broken stocks, cage-like distortion, broken cores deformation.
7, rope diameter reduction of not more than 7% of the nominal diameter,
8, the rope should not exceed the number of broken wires "check gauge" value.

Finally you are prompted rope pulling Hoist equipment  during operation speed and stability should not exceed the load operation, to avoid shock loading.
