FIELD: transportation.
SUBSTANCE: group of inventions relates to a device, that allows easy reverse maneuvering of the tractor, to which a trailer is attached. Trailer (1) has a frame (2) of the trailer, the main axle (3), a device (4) of fixed connectors for its connection to a towing vehicle (5), an ancillary axle (6), lifting means (M, V, 6d), and means ( 6e, 7) of orientation towards the ancillary axle (6), according to the trajectory of reverse motion of the tractor (5). Lifting means (M, V, 6d) are made to selectively move the one among the main axle (3) and the ancillary axle (6) between a first position, in which the ancillary axle (6) is raised above the ground with respect to the main axle (3), and a second position, in which the ancillary axle (6) is lowered towards the ground (S) below the main axle (3).
EFFECT: achieved by facilitating the movement and reverse maneuvering, due to the possibility of bringing the trailer to the tractor axis trajectory ago.
