The double tipping trailer is constructed on a chassis (1), which is mounted so as to pivot on the end of the towing beam (4), around the axis (3). The chassis carries a hopper body (5), which is mounted so as to pivot around an axis (6), which is carried by a support arm, fitted at the rear end of the chassis. This second tipping motion is produced with the aid of a jack (7), and a mechanism (10) to lock the chassis to the towing beam.
