[0002] In the installation of roller bearings, the traditional clumsy construction method is still adopted, using lifting belts and manual labor to install the roller bearings. The existing construction technology has the following disadvantages: (1) When using rigid lifting tools, the rigid lifting tools directly contact the roll bearings, causing friction during the lifting process, causing the roll bearing surface to wear.

[0003] (2) When lifting with a lifting belt, the lifting belt passes directly through the bearing and is lifted into position, making it impossible to directly install the bearing.

[0004] (3) The traditional method requires 3 to 4 people to cooperate in lifting. After lifting to the designated location, it cannot be directly lifted by a crane. Subsequent manual handling and installation are required, and the installation labor loss is large. Summary of the Invention
