摘要

The trailer for transporting livestock has a device for pivoting it about the axle of its two wheels so that the back of the floor rests on the ground. This consists of a system of three joints attached to the tow-bar. The trailer for transporting livestock has a device for pivoting it about the axle of its two wheels so that the back of the floor rests on the ground. The device consists of a lower joint (11) attached to the chassis (2) by a bracket (20) and about which the tow-bar (7) pivots. A second joint (13) is also attached to the bracket above the first. A third joint (14) is located between the chassis and the attachment point (A) on the tow-bar and is linked to the second joint by a jack (16), so that the distance between the two joints can be varied. the trailer can be raised and lowered by changing the shape of the triangle formed by the three joints.
