Description

Oil-resistant and wear-resistant cable storage frame lifting appliance cable Technical Field The utility model relates to the field of cables, in particular to an oil-resistant and wear-resistant cable storage frame lifting appliance cable. Background The cable storage frame lifting appliance cable is a special connecting cable, is mainly used for cable basket storage control and connection of medium-large equipment, and is particularly suitable for vertical cage occasions with high mechanical stress. The cable storage frame lifting appliance cable is widely applied to the hoisting industry, such as construction sites, mining machinery, container cargo handling, garbage disposal plants, railway platforms, cranes of shipyards and other severe working environments. In the long-term use process of the existing cable storage frame lifting appliance cable, particularly in severe environments (such as humidity, greasy dirt, low temperature and the like), the outer sheath of the cable storage frame lifting appliance cable is easy to wear and age, even cracks are generated, so that the cable performance is reduced, and the service life is shortened. The existing cable storage frame lifting appliance cable is easy to shift due to factors such as wind force and the like due to lack of enough weight and stability, and normal use and safety of the cable are affected. When some cable storage frame lifting appliance cables are subjected to mechanical damage such as friction and extrusion, the cable storage frame lifting appliance cables are easy to damage and break, and the cable performance is reduced. During the installation or use process, some cable storage frame lifting appliance cables may be damaged due to overlarge pulling force, so that the cables cannot be used normally or need to be replaced frequently.
