[0002] A hydraulic puller is a puller that moves forward directly with the hydraulic starting rod. The push rod itself does not rotate, and the hook seat can be adjusted forward and backward directly with the thread. When operating, just swing the handle slightly back and forth, the hydraulic starting rod moves forward, and the hook moves backward accordingly, and the object being pulled is pulled out.

All the pairs of wheels must be removed during each overhaul to repair the pump body and reducer. The removal of the wheels requires the use of a hydraulic puller. During the removal process, it takes 3-4 people to operate the hydraulic puller at the same time to remove a pair of wheels. Supporting the hydraulic puller is not only time-consuming and labor-intensive, but the manpower support is also unstable, affecting the maintenance efficiency.

[0004] Therefore, there is an urgent need to provide a combined adjustable hydraulic puller tooling to improve the maintenance efficiency compared with the existing technology. Utility Model Content
