This type of crane has a large crawler ground contact area, good passability, strong adaptability, and can travel with a load, making it very suitable for hoisting operations on construction sites. In addition, crawler cranes can also perform various operations such as earth excavation, soil ramming, and pile driving. However, due to its relatively slow traveling speed, other vehicles are required to transport it over long distances to transfer construction sites. When a crawler crane is in use, it is necessary to guide its steel wire rope, and thus a guiding pulley device is required. When disassembling and assembling the guiding pulley in the existing guiding pulley device, it is very inconvenient. When the guiding pulley is worn, it is very troublesome to replace, increasing the operation difficulty of the operator and reducing the work efficiency. Summary of the Utility Model
