It also has step-type treads mounted on tracks and running continuously, commonly known as escalators or moving walkways, which are fixed lifting equipment serving specified floors. A vertical elevator has a car that runs between at least two vertical rigid guide rails.

[0003] Elevators need to be maintained regularly at intervals, which requires personnel to perform maintenance or inspections at high altitudes. This can easily lead to the risk of falling when inspecting at heights. When repairing elevators, a safety rope is required to secure the body. If the safety rope slips too quickly, there is a risk of falling, causing injuries to personnel during inspection.

[0004] In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. Because traditional elevators are constructed at high places, people are hung with safety ropes, and it is easy to slip if one accidentally steps on empty air, which leads to the use of a pulley device; 2. Because the sliding speed is too fast during the traditional construction process, it is easy to slip, which leads to the risk of falling. Utility Model Content
