  • the load support system 3 In order to allow the weight of the vehicle to be towed 4 to be taken up, which then presses on the two carrier forks 7, the load support system 3 must be placed in the deployed position.
  • first arm 12 of each hinge arm assembly is pivoted around its second pivot axis A2 in the direction of the crosspiece 6, until the first arm 12 is in contact with the wall of the support 60 of the crosspiece 6 and is received in the corresponding longitudinal groove 8 carried by the crosspiece 6.
  • second arm 13 of each hinge arm assembly is pivoted downwards around its third pivot axis A3, up to 'so that the second arm 13 and the first arm 12 is aligned along the same longitudinal axis, the wheels 15 then coming into contact with the ground.
  • the rod 9 integral with each fork 7 is received in the corresponding holes 13b of the second arm 13, thus allowing the locking in the deployed position of each arm assembly 12-13.
  • each wheel support axle 14 is oriented in its through bore 13a such that the wheel or wheels 15 that it carries have their axis of rotation transverse to the direction of advance or retreat of the towing vehicle.
  • each hinge arm assembly in the position in which the second arm 13 is aligned with the first arm 12 is such that when the load support system 3 is in the deployed position, the wheels 15 are positioned under the first branch 70 of each carrying fork 7.
  • the load support system 3 according to the invention in its deployed position can be considered as a third axle, the first axle being the rear axle of the towing vehicle and the second axle being the axle of the vehicle to be towed 4 in contact with the ground.
  • the weight of the raised part of the vehicle to be towed 4 no longer rests on the rear axle of the towing vehicle.
  • the passage from the stowed position to the deployed position, and vice versa, can be carried out manually by an operator or automatically.
