Description
Technical field
The present invention relates to a kind of worker's operation post, be specifically related to a kind of ladder type operation post.
Background technology
Folding ladder claims " double ladder " again, by hinged the forming of preceding ladder and ladder upper end, back.The lower end can be opened during use, and integral body is herringbone self-support state, need not support by other; Folding back is whole as single ladder, and is easy to carry.After guaranteeing that folding ladder opens, have stable braced structures, near the upper end of folding ladder, be provided with locker usually.This type of device can constitute triangular framing with preceding ladder and back ladder after folding ladder opens, thus the ladder stabilizer after keeping opening.Owing to have above advantage, so folded ladder is widely adopted.
Yet when climbing up folding ladder, the operator need trample at ladder shelves (claiming again to mark time) and carry out work high above the ground, since the underfooting to trample area less, center of gravity moves inconvenience, more can not the turned position, change direction, carry out operation in a big way, influence operating efficiency.
Summary of the invention
The invention provides a kind of ladder type operation post, its objective is to solve folding ladder of the prior art trample area less and can not the turned position, the problem of changing direction.
For achieving the above object, the technical solution used in the present invention is: a kind of ladder type operation post, and its innovation is: comprise a folding ladder and the workbench of being located at folding ladder top;
