<p>The application relates to a pulling system for a vehicle including a chassis connected, via a support device, to at least one wheel (11, 13) of the vehicle, which is capable of rotating about a first axis (Y) and capable of supporting the vehicle on the ground, the system including: at least one first wheel (60, 62) capable of rotating about a second axis, the first wheel being motor driven; an attachment means (30, 54) for attaching the pulling system to the support device and/or to a hub of the wheel of the vehicle such that the first axis (Y) and the second axis are parallel and offset in a rolling direction (R2) of the first wheel (60, 62); and at least one lifting device for lifting the vehicle from a rest position, in which the pulling system does not bear the weight of the vehicle, to an operating position, in which the pulling system bears a portion of the weight of the vehicle, the attachment means and the lifting device being capable of allowing a rotation of the wheel of the vehicle on the ground in the operating position. The application further relates to a method for ensuring the safe pulling of a vehicle on the ground, in particular on a deck of a boat.</p> |
