1. A conveyor for moving four-wheeled vehicles, the conveyor comprising:
a conveyor platform provided with tire-chock arms movable between a retracted position and a position in which the tire-chock arms engage with treads of tires of a four-wheeled vehicle; and
a propulsion unit including a frame to which two lateral subunits are secured, each of the two lateral subunits comprising a motorized and directional wheel configured to be oriented independently of one another and a height adjustment system that connects the conveyor platform to the frame of the propulsion unit,
wherein the conveyor platform includes a first hollow proximal box, a second distal box that slides within the first hollow proximal box, a longitudinal slide connecting the first hollow proximal box and the second distal box, and a pneumatic or electric cylinder configured to adjust a position of the second distal box relative to the first hollow proximal box, the second distal box comprising a caster connected to the second distal box by a lift pad.
