Wire rope electric hoist is an irreplaceable lifting equipment in modern construction.
1. Galvanized and aluminum-plated
For wire rope electric hoists that often work in harsh environments, galvanized and aluminum-plated wire ropes can be selected. The galvanized or aluminum-plated surface of these ropes will form zinc hydroxide and aluminum hydroxide even if they are exposed to the outside, which can effectively prevent the corrosion of wire ropes.
2. Regular oiling
For frequently used wire rope electric hoists, the wire ropes should be oiled regularly. The hemp core of the new wire rope generally contains 12-15% grease, while the scrapped wire rope contains 2.4% grease in the loss part. Tests show that the amount of broken wires in the oiled wire rope is about half of the amount of broken wires in the unoiled wire rope. Therefore, regular oiling of the wire rope can effectively reduce the corrosion of the wire rope electric hoist.
