Description

Mobile Folding Maintenance Platform

technical field

The invention relates to a maintenance tool, in particular to a foldable platform used for maintenance.

Background technique

The commonly used climbing tool for maintenance is the ladder, which is inconvenient to carry. During the maintenance process, the staff on the ladder must wear safety belts, and it is inconvenient to move back and forth. There is a danger of falling, and the ladder is unstable, so it is necessary to set up a special person on the ground to support the ladder. Only one person can stand and work on the ladder, and the work efficiency is low. Some ladders are equipped with a platform on which people can stand. For example, pulleys are installed at the bottom of the ladder legs in the invention patent CN102373877A, so that the ladder can be moved. Pulleys are also installed on the legs, which can facilitate the maintenance personnel to stand on the ladder. When the ground is slippery, since the pulleys are installed on the outriggers and the legs of the ladder, this kind of ladder is easy to slide, and the maintenance personnel may fall from the ladder. fall, causing personal danger. The ladder legs on both sides extend to both sides and are rigidly connected with the bracket, resulting in a bulky ladder that needs to occupy a large area for storage.
