Abstract

The invention relates to a load-lifting device comprising a main body (2) including: at least one rear rolling element (7) located in a rear zone (8) of the device and 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 than the rear zone (8) and 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) bear on the ground, while, when not loaded, the from rolling elements (10) do not rest on the ground, thereby improving the manoeuvrability of the device.
