Platform support device for lifting loads or persons the height of a structure

Abstract

The invention relates to a device for supporting a platform (1A, 1B) that is used to lift loads or persons the height of a structure. Together with a platform (1A, 1B), the inventive device comprises winch-type platform-lifting elements (2, 3) and modular assemblable mast-forming elements (4, 6). According to the invention, each mast element (4, 6) is installed using the load platform (1A, 1B) which can be connected to the masts by means of: (i) the aforementioned winch-type lifting elements (2, 3) which can be disconnected at will from the masts, and (ii) means (5) for temporarily blocking the movement of the platform (1A, 1B) in relation to a modular element (4, 6) of each mast. In this way, when the movement of the platform (1A, 1B) is blocked, a modular element (4, 6) can be added to, or removed from the top of the masts in accordance with the desired platform (1A, 1B) lifting height. The invention is characterised in that the platform (1A, 1B) is positioned between two modular independent masts which form a lifting and guiding path (12), each mast having at least two guiding paths (11, 12) which are arranged in order to co-operate with a platform (1A, 1B), enabling the asynchronous movement of said platforms (1A, 1B).

Description

technical field [0001] The present invention relates to a platform support apparatus for lifting heavy objects or persons at the height of a building, in particular for performing work on said building, comprising: in combination with the platform, for controlling the platform as required Lifting level winch platform lifting elements, combineable modular components forming masts to achieve desired heights, each mast element is mounted from a weight platform which can be connected to the mast by winch lifting elements on the one hand , the lifting elements can be detached from the masts as required, and on the other hand the platform is temporarily fixed by means of modular elements for each mast to allow when the platform is fixed according to the desired raised height of the platform at Means for adding or removing at least one modular element at the top of the mast. Background technique [0002] Work at the facade level of buildings with very high heights is often carried...

AI Technical Summary

Problems solved by technology

However, the system for guiding the platform along the uprights of the ladder is not described here

During vertical movement, the platform is also free to move horizontally, which makes the system dangerous and unsuitable for working at very high heights

Also, because the ladder is integral with the diagonal members, one of the ladders cannot be removed without removing the other

[0008] Therefore, the aforementioned document does not describe a scaffold that can be used at very high heights, the platform of which can be moved vertically over the entire height of the column without adversely affecting the safety of the assembly

Moreover, none of these documents describe a device that allows the asynchronous movement of two plates along the two guide surfaces of the same mast
