A transport vehicle (100, 1000) including: - a chassis (102, 1002) including two longitudinal bars on each of which a wheel is mounted and - a load (150, 650) disposed between the longitudinal bars, each longitudinal bar having at the rear of the wheel, a first fixing system and, at the front of the wheel, at least a second fixing system, the load (150, 650) having, for each first fixing system, a first hooking means (158, 658) and for each second fixing system, a second hooking means (156, 656), each fixing system (152, 154) and the associated hooking means (156, 656, 158, 658) being configured to ensure a removable connection therebetween, the load (150, 650) being hooked on the chassis (102, 1002) from a position where the load (150, 650) rests on the ground: - by lifting the front part of the chassis (102, 1002) by rotation around the axis of the wheels so that each first fixing system is positioned under the first corresponding hooking means (158, 658), then - by lowering the front part of the chassis (102, 1002) by rotation around the axis of the wheels so that, initially, each first fixing system bears under the corresponding first hooking means (158, 658) and lifts it, then in a second step so that each second fixing system is hooked with the second corresponding hooking means (156, 656), and the load (150, 650) being unloaded from the chassis: - by lowering the front part of the chassis (102, 1002) by rotation around the axis of the wheels to place the front of the load (150, 650) on the ground and disconnect each second fixing system and the corresponding second hooking means (156, 656), then - by lifting the front part of the chassis (102, 1002) by rotation around the axis of the wheels to place the rear of the load (150, 650) on the ground and disconnect each first fixing system from the corresponding first hooking means (158, 658) characterised in that the load includes a pallet and a frame placed under the pallet by insertion of the frame through one side of the pallet, the H-shaped frame having a longitudinal beam and two transverse beams, the ends of each transverse beam having a second hooking means or a first hooking means. -
