Description

Technical Field

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

[0002] An elevator is a permanent transportation device that serves several specific floors within a building, with its car moving between at least two rigid guide rails perpendicular to the horizontal plane or at an angle of inclination less than 15° to the vertical. There are also escalators, where steps are mounted on a continuous track and run; these are commonly known as moving walkways or automatic stairs. They are fixed lifting devices serving designated floors. A vertical elevator has a car that runs between at least two rigid guide rails that are vertical or at an angle of inclination less than 15°. The size and structure of the car facilitate passenger entry and exit or loading and unloading of goods. Conventionally, regardless of its drive method, elevator is used as a general term for vertical transportation tools within a building.

[0003] However, existing safety maintenance racks lack height adjustment functionality and are typically designed as ladders. This results in insufficient height, preventing users from performing maintenance tasks properly. Therefore, we propose a new safety maintenance rack for elevator maintenance. Utility Model Content
