Definitions
- the angle of the minimum opening of the levers has a proportional influence on the overall height of the folded lifting mechanism. Reaching the minimum height of the lifting platform above the base area is very important in particular for the V-level jacks, the goods lifting platforms and the lifting platforms consisting of several sets of scissor mechanisms that are interconnected. In the known lifting devices, this requirement was met by "inclined" mounting of the hydraulic motor. Dsbsi one end part of the hydraulic motor was connected to the longer arm of the first lever and the other end part of the hydraulic motor to the shorter arm of the second lever.

Abstract
Un écarteur, notamment pour mécanismes de levage à leviers disposés par paires, comprend une chambre (8) de volume variable formée par un soufflet élastique et susceptible d'être racordée à l'amenée et à la sortie d'un milieu sous pression. La chambre comprend deux fonds (16, 17) sur lesquels sont fixés des couvercles (6, 7). Les fonds (16, 17) sont pourvus de deux languettes opposées (13, 13', 14, 14') orientées vers les couvercles opposés (6, 7). L'écartement entre les languettes opposées (13, 13') du premier couvercle (6) est supérieur à l'écartement entre les languettes opposées (14, 14') du deuxième couvercle (7). Les deux languettes opposées (13, 13', 14, 14') sont pourvues d'éléments coaxiaux (9, 9', 11, 11') qui forment des liaisons rotatives avec le mécanisme à leviers. Les axes des éléments coaxiaux (9, 9', 11, 11') de chaque couvercle (6, 7) coupent la ligne de connexion (18) entre les centres de gravité de la surface des deux fonds (15, 16) de la chambre (8), à un point situé entre ces fonds (15, 16).A spreader, in particular for lifting mechanisms with levers arranged in pairs, comprises a chamber (8) of variable volume formed by an elastic bellows and capable of being connected to the supply and to the outlet of a pressurized medium. The chamber comprises two bottoms (16, 17) on which covers (6, 7) are fixed. The bottoms (16, 17) are provided with two opposite tongues (13, 13', 14, 14') oriented towards the opposite lids (6, 7). The spacing between the opposing tabs (13, 13') of the first cover (6) is greater than the spacing between the opposing tabs (14, 14') of the second cover (7). The two opposing tongues (13, 13', 14, 14') are provided with coaxial elements (9, 9', 11, 11') which form rotatable connections with the lever mechanism. The axes of the coaxial elements (9, 9', 11, 11') of each cover (6, 7) intersect the line of connection (18) between the centers of gravity of the surface of the two bottoms (15, 16) of the chamber (8), at a point located between these bottoms (15, 16).
