Improvements to trailers and/or semi-trailers.

摘要

The trailer or semi-trailer is constructed with a chassis (1) and an over-frame (9) which are linked together by a fixed pivot and by a travelling slide at their head, there are at least two cylinders (7, 10) operating with fluid under pressure, of which one (10) is the tipping cylinder which links the centre rear of the chassis to the head of the container box (16) mounted on the over-frame (9) so as to cause it to rotate in an arc, and the other is the braking cylinder which links the chassis with the axle on the trailer or semi-trailer and causes travel or locking between the chassis and the over-frame at any one whatsoever of the manifold positions which exist between the horizontal travel position at one extreme, and the maximum tip position at the other.
