Abstract
In a trailer adapted to be connected with a front end thereof to a rear-end of a carrier vehicle, and where the front end of the trailer is held at a predetermined height above ground when connected to the carrier-vehicle, the trailer includes a frame defining a trailer frame plane extending in a hauling position of the trailer substantially parallel to the ground, a front extension and a rear extension of the trailer extending substantially along the trailer frame plane, the front extension being connected between the front end and the trailer frame, the trailer front end including an elongated drawbar defining a drawbar plane subtending a first angle close to 180.degree. with the trailer frame plane in the hauling position, the improvement includes an angle varying device for changing the first angle to a second angle when the trailer frame is in a position for providing access to vehicles to be loaded onto the trailer for subsequent passage to the carrier vehicle, the predetermined height being similar in the hauling and vehicle access positions of said trailer frame, whereby the rear extension touches the ground when the drawbar plane subtends the second angle with the trailer frame plane, so as to provide a gently sloping vehicle access ramp.
