Electric wire rope hoist, wire rope maintenance should pay attention to what?
A run: wire rope during operation should speed stability not overload operation, to avoid shock loading.
Maintenance: use a wire must be checked regularly and make a record of wire rope wear, broken wires, corrosion, and hooks, rings should be checked regularly check the contents of the addition to the above cleaning refueling, the lubricated wheel slot vulnerable parts wear. Found anomalies must promptly adjust or replace. Like many other materials as in the use of the early and late, the damage rate of the rope is very rapid. Especially in the initial period, the damage is often caused by the following reasons:
Third, check the records of wire rope has been coated in the manufacture of grease, but after running grease will gradually less and wire rope surface stained with dust, debris and dirt, causing the wire rope and sheave wear and wire rope Health rust, therefore, should be cleaned regularly and refueling. The easy way is the selection of wire brushes and other tools to wipe off the the rope surface dust and dirt, surface heating and melting of the wire rope grease evenly smear the rope surface, the 30th or 40 oil spray and poured it on a wire surface, but do not spray poured on the steel rope surface, but do not spray pouring too much pollution in the environment. Chosen the wrong wire rope; improper installation; equipment and wire rope debugging. Use after the initial period, the electric wire rope hoist long-term stable state (precondition must provide the necessary care and maintenance). The sudden rise in the proportion of the final damage, which is the replacement of the wire rope electric hoist signal.
Often occur in the use of the final damage following situations: wire breakage, wire rope diameter smaller the wire rope hardening, these can not be said that the wire rope would not be bad, but at least you can extend its service life.
