In ancient Egypt, when building the pyramids, the Egyptians used a primitive lifting system to carry objects to heights. The basic principle of this system is still used today. Simply put, as a counterweight descends, its load platform rises.

[0003] In previous mechanisms, the stability of the traction wheel installation was not particularly high. In daily use, due to the long usage time and the heavy weight of the elevator, this led to instability in daily use, requiring replacement or repair, and safety accidents may occur in the case of aging.

The mounting shaft is located in front of the speed detection disk. The number of the support bar one is set to four, and the four support bar ones are located on the surface of the connecting disk one. The surface of the fixed block is clamped in the groove on the front side of the traction wheel body.

[0010] According to the above technical solution, the external mechanism is connected by providing a clamping recess on the clamping block to fix the entire mechanism.

[0011] As a further improvement of the above solution, a hexagonal nut is threadedly connected to the surface of the traction sheave body.
