AI Technical Summary
The positioning of existing elevator cars is inaccurate due to factors such as guide rail wear, installation errors, and running speed, which affects comfort and poses safety risks.
The system employs a rolling engagement between guide bars and guide blocks, combined with the lifting and lowering motion of the steel rope wheel and traction steel rope. This reduces frictional resistance through ball bearings and limits the movement of the steel rope wheel through the traction block, ensuring the stability and accuracy of the elevator car.
It improves the stability and positioning accuracy of the elevator car during the lifting and lowering process, reduces safety risks, and enhances passenger comfort.
