Description

Technical Field

[0001] This utility model belongs to the field of mechanical engineering technology, specifically relating to a lifting tool for maintaining the slewing bearing of a hydraulic forklift. Background Technology

[0002] A hydraulic loader is a type of engineering machinery that uses a hydraulic system as its primary power source for loading and unloading operations. It mainly consists of a working device (including the bucket and boom), a hydraulic system, a frame, a power unit, and a traveling mechanism. During operation, the hydraulic system controls the raising and lowering of the boom and the tilting of the bucket, enabling the flexible scooping and transport of bulk materials such as sand, coal, and ore. Compared to traditional mechanical loaders, hydraulic loaders offer more precise operation, smoother movement, and higher power transmission efficiency, making them widely used in construction, ports, and mining industries.

[0003] As the operating hours of the hydraulic loader increase, the slewing bearing of the equipment has reached its overhaul period, and the replacement of the slewing bearing is imminent. Since the slewing bearing is a key component connecting the upper and lower vehicle bodies, there are many interfering components around it, the maintenance space is limited, and auxiliary equipment cannot enter for disassembly and assembly. Moreover, the slewing bearing weighs 10 tons, and the safety and maintenance efficiency of replacing it with general lifting tools cannot be guaranteed.

[0004] In view of the above factors, this utility model provides a lifting tool for the maintenance of the slewing bearing of a hydraulic loader. This device can ensure the safety of the maintenance of the slewing bearing of the hydraulic loader, while improving the maintenance efficiency and avoiding delays in the project schedule caused by excessive maintenance time, thus meeting the maintenance needs of hydraulic loaders.
