1. Trailer with at least a tilting axle unit comprising an anterior zone or front end (11) equipped with a coupling device (110) joinable to a tractor (M), an intermediate loading deck (13), a posterior zone or rear end (12) adjacent to a rear support (2), said rear support (2) comprising one or more axles (21) each connected to one or more wheel groups (210) to sustain said trailer while in a run configuration,
characterized in comprising a telescopic support or slide (3) and a fifth-wheel coupling (4), connected each other by means of a socket or fifth-wheel socket (31), said telescopic support or slide (3) being connected to said rear support (2) and movable so that it slides in said socket (31) by means of first moving means (100) along a first axis (X) substantially parallel to the direction of the longitudinal extension of said trailer,
said rear support (2) being rotatable and connected to said telescopic support or slide (3) by means of a hinge or pivot (221) that can be rotated around a second axis (Y) substantially parallel to the ground and perpendicular to said first axis (X), and being movable by means of second moving means (200) around said hinge or pivot (221),
said fifth-wheel coupling (4) being placed in correspondence of said loading deck (13) and being rotatable, by means of third moving means (300), around a third axis (Z), substantially perpendicular to the ground and to said first axis (X) and to said second axis (Y), so that it rotationally drags said telescopic support or slide (3) and said rear support (2), to allow the loading of a vehicle on said loading deck (13) in correspondence of said posterior zone or rear end (12).
