Maintenance of mine wire rope

The main lifting device must be equipped with a spare cable for inspection. The wire ropes in use shall be oiled at least once a month according to the condition of the roadway and corrosion conditions. The lifting wire rope of the friction wheel lifting device is only allowed to be coated and immersed in the special wire rope oil (addition of grease); however, the steel wire rope that does not bypass the friction wheel portion must be coated with anti-corrosion oil.
