Description

Technical Field

[0001] The utility model relates to the technical field of tower cranes, in particular to a tower crane steel wire rope lubrication device. Background Art

[0002] Tower crane is the most commonly used lifting equipment on construction sites. It is also called a tower crane. It is connected section by section and is used to lift raw materials for construction such as steel bars, wooden slats, concrete, steel pipes, etc. Tower crane is also an indispensable lifting equipment on construction sites.

[0003] During tower crane operation, the tower crane is responsible for driving the hook to move vertically and horizontally. However, a noteworthy issue is that during the movement of the tower crane, due to technical and operational limitations, it is often difficult to effectively lubricate the wire rope on the hook. This lack of lubrication will directly affect the friction coefficient and service life of the wire rope. In the long run, it may cause increased wear of the wire rope, and in severe cases it may even break when lifting heavy objects. This situation will not only affect work efficiency, but also cause serious safety hazards, threatening the safety of on-site workers and the surrounding environment. Therefore, ensuring timely lubrication and maintenance of the tower crane wire rope is crucial to ensuring the safe operation of the tower crane.

[0004] Therefore, it is necessary to provide a new tower crane wire rope lubrication device to solve the above-mentioned technical problems. Utility Model Content
