Abstract
(EN)
A lift device comprising: a base (12) having a plurality of wheels (14A, 14B); a retractable lift mechanism (20) having a first end (23, 62) coupled to the base (12) and being moveable between an extended position and a retracted position; a work platform (22) configured to support a load, the work platform (22) being coupled to and supported by a second end (24, 70) of the retractable lift mechanism (20); a linear actuator (26) configured to selectively move the retractable lift mechanism (20) between the extended position and the retracted position, the linear actuator (26) having an electric motor.
(FR)
Cette invention concerne un dispositif de levage, comprenant : une base (12) ayant une pluralité de roues (14A, 14B) ; un mécanisme de levage rétractable (20) ayant une première extrémité (23, 62) reliée à la base (12) et étant mobile entre une position déployée et une position rétractée ; une plate-forme de travail (22) configurée pour supporter une charge, la plate-forme de travail (22) étant reliée à une seconde extrémité (24, 70) du mécanisme de levage rétractable (20) et supportée par celle-ci ; un actionneur linéaire (26) configuré pour déplacer sélectivement le mécanisme de levage rétractable (20) entre la position déployée et la position rétractée, l'actionneur linéaire (26) ayant un moteur électrique.
