Abstract

L'invention concerne un appareil (10) pour lever et transporter une charge, notamment sous la forme d'un conteneur (11), comprenant un châssis support (12), des moyens ou des roues (16, 18) pour déplacer l'appareil par rapport au sol, des moyens (20) pour lever la charge comprenant un mât correspondant muni d'une première partie (20a) reliée au châssis (12) et une deuxième partie (20b) extensible par rapport à la première partie (20a), et des moyens (22) pour saisir la charge, capables de se déplacer le long du mât (20). L'appareil comprend également des moyens de traction ou de commande du mouvement (24, 24) et des moyens (26, 26) pour commander le levage des moyens de préhension de la charge, les moyens de traction (24, 24) et/ou les moyens (26, 26) de commande du levage étant sous la forme de moyens moteurs électriques correspondants qui sont alimentés par des moyens accumulateurs d'électricité (30) correspondant par le biais de moyens de commande (314, 314, 316, 316) correspondants. L'appareil est conçu de telle sorte que pendant les courses de descente de la partie extensible du mât, les moyens moteurs électriques (26, 26) des moyens de levage (20) sont avantageusement conçus pour faire office de moyens de génération d'électricité, laquelle est délivrée aux moyens accumulateurs d'électricité (30).
