Ground-loading transport vehicle comprising - at least two wheels, - a supporting frame comprising a U-shaped part comprising two arms (8, 9) facing one another, the wheels being fixed onto the two arms (8, 9) of the U-shaped part, - a load-holding device, such as a dumpster, characterized in that it further comprises: - a lifting frame movably linked to the supporting frame via a coupling system, - the load-holding device being borne by the lifting frame, making it possible to hold the load, this load-holding device at least partly occupying the interior space of the U-shaped part extending between the two arms (8, 9) of the U-shaped part, such that a rotation axis of the wheels extending between the two wheels passes through the load-holding device when the load-holding device is in a position on the ground, - the lifting frame being mobile relative to the supporting frame, this lifting frame ensuring the switching of the load-holding device from the position on the ground making it possible to load the load-holding device to at least one raised position making it possible to move the vehicle, - the coupling system ensuring a displacement of the lifting frame such that the centre of gravity of a load of the load-holding device is displaced towards the rear of the vehicle when said load-holding device switches from the position on the ground to the raised position, - the coupling system exhibits at least one first kinematic behaviour in which the holding device is displaced towards the rear of the vehicle by tilting towards the rear of the vehicle so as to ensure that the load of the holding device is held when said load-holding device switches from the position on the ground to the raised position. - at least two wheels, - a supporting frame comprising a U-shaped part comprising two arms (8, 9) facing one another, the wheels being fixed onto the two arms (8, 9) of the U-shaped part, - a load-holding device, such as a dumpster, - a lifting frame movably linked to the supporting frame via a coupling system, - the load-holding device being borne by the lifting frame, making it possible to hold the load, this load-holding device at least partly occupying the interior space of the U-shaped part extending between the two arms (8, 9) of the U-shaped part, such that a rotation axis of the wheels extending between the two wheels passes through the load-holding device when the load-holding device is in a position on the ground, - the lifting frame being mobile relative to the supporting frame, this lifting frame ensuring the switching of the load-holding device from the position on the ground making it possible to load the load-holding device to at least one raised position making it possible to move the vehicle, - the coupling system ensuring a displacement of the lifting frame such that the centre of gravity of a load of the load-holding device is displaced towards the rear of the vehicle when said load-holding device switches from the position on the ground to the raised position, - the coupling system exhibits at least one first kinematic behaviour in which the holding device is displaced towards the rear of the vehicle by tilting towards the rear of the vehicle so as to ensure that the load of the holding device is held when said load-holding device switches from the position on the ground to the raised position.
