Visual assistance to on-ground movement of a lifting platform

Abstract

An aerial work platform comprises a control desk (30) for moving the platform (20) into a working position at a height and for moving the chassis (2) on the ground in the forward (FAV) and backwards (FAR) directions. In order to avoid confusing these two directions of travel as a result of the variable orientation of the desk (30) with respect to the chassis (2), the direction of travel selected on the control desk (30) is indicated to the operator by activation of at least one visual indication (63a, 64a, 64b, 70.i, 72) located on the side of the chassis (2) which corresponds to the selecteddirection of travel or that has a shape that points in the selected direction of travel (FAV, FAR). A screen (40) also indicates the selected direction of travel (FAV, FAR) in the form of a display which transfers the preceding visual indication system onto the screen (40) in relation to the azimuthal direction of the chassis (2) with respect to the desk (30).

Description

technical field [0001] The present invention relates to the field of mobile elevating work platforms for workers (also denoted by the acronym MEWP), also commonly known as aerial work platforms. Background technique [0002] An aerial work platform is a machine intended to enable one or more persons to work at heights. They usually include a chassis and a lifting structure mounted on the chassis and supporting a work platform for receiving personnel and equipment. [0003] The lifting structure makes it possible to raise the working platform from a lower position on the chassis to a working position with a certain height, and vice versa. With regard to so-called aerial work platforms with arms, the lifting structure usually consists of a turntable mounted to pivot on the chassis and on which is mounted the arm supporting the work platform, which makes it possible to change the orientation of the arm relative to the chassis and thus the The orientation of the work platform ...

AI Technical Summary

Problems solved by technology

[0011] One disadvantage of this solution: the operator does not necessarily know the reversal of the correspondence between the direction of action on the control handle and the final direction of movement of the chassis on the ground, if he often uses other altitudes that do not use this solution Even more so for work platforms

If the solution is applied to rotary table aerial work platforms and / or aerial work platforms with detachable and movable consoles on the work platform, these, for the reasons already mentioned in relation to other corresponding existing solutions downside is even worse
