Abstract (en)

A load-lifting device, comprising a main body (2), which comprises at least one rear rolling element (7), located in a rear zone (8) of the device and which can be actuated by the user in order to manoeuvre the device; at least one front rolling element (10) located in a front zone (11) of the device closer to the force applicator (5) than the rear zone (8); an intermediate rotary rolling element (12), located between the rear zone (8) and the front zone (11) of the device and elastically connected to the main body (2), the centre of gravity of the device being disposed behind the intermediate rotary rolling element (12) such that, when loaded, all of the rolling elements (7, 10, 12) rest on the floor, while, when not loaded, the front rolling elements (10) do not rest on the floor, thereby improving the manoeuvrability of the device.
