Different traction ratios can be formed by passing the traction rope around the return rope pulley as needed. In the elevators installed on the existing market, most of the return rope pulleys are fixed on the elevator upper beam. This setting method increases the requirements for the top height of the elevator shaft, resulting in an increase in the fixed height, which makes it very inconvenient for maintenance personnel to cross the upper beam on the top of the elevator car, and increases the possibility of falling, increasing the risk factor.

[0003] The existing patent (Announcement No.: CN211496508U) discloses a return rope pulley device for elevators.
