ABSTRACT:
The present invention is related to a transport trailer with a suspended articulated platform. The device comprises a platform (1) upon which is pivotally attached a cradle formed of two interdependent arms (6) of a shaft spanning the platform transversely near the longitudinal center of the platform. The fore arms (P'2) are pivotally connected at (P2-P'2). The top of each arm is linked to a fork made up of two tie-beams (2) and a T-shaped tow bar (3). These tie-beams are pivotally connected at (P3-P'3) and (P4-P'4). The hitch device (4) is linked to the hauling vehicle, which, in moving forward, exerts a force (F). This towing force results in the raising of the platform (1) so that it pivots around (P1-P'1) and (P2-P'2). This rotation takes place around the wheel shafts (5) so that they become locked in with the aid of the wedges (10). In the upright position, as shown, the tie-beams (2) are locked against the fore arms (6) at points (S) and (S').
