[0002] As a common large-scale hoisting equipment on construction sites, tower cranes play a crucial role in the construction process of buildings. The wire ropes of tower cranes are key components that bear the lifting and lowering of heavy objects. They are in a working state of high load and frequent friction for a long time. In order to reduce the friction loss between the wire ropes and pulleys and extend the service life of the wire ropes, it is usually necessary to regularly oil and lubricate the wire ropes.
