Description

Technical Field

[0001] This utility model relates to the field of elevator maintenance technology, specifically to a mobile maintenance platform. Background Technology

[0002] When performing maintenance or routine inspections on elevators, maintenance personnel need to either go up to the top of the elevator car or down to the bottom shaft entrance, depending on the location being inspected. Current elevator car maintenance platforms are generally ladder-like structures, allowing maintenance personnel to climb to the top of the car. When descending to the bottom shaft entrance, maintenance personnel typically use a ladder to enter.

[0003] Because both the elevator car maintenance platform and the ladder need to be carried, the transportation burden is increased, and sometimes only the elevator car maintenance platform is carried due to negligence, the ladder being occupied, or insufficient transportation space. Maintenance personnel then have to climb and jump to enter the bottom shaft entrance. Since the ground at the bottom shaft entrance is uneven and poorly lit, this method easily leads to injury for maintenance personnel, posing a significant safety hazard. Utility Model Content
