<p>Landing gear (1) for raising and lowering a trailer. The landing gear comprises two support legs (4) and two pressure fluid cylinders (5). Each support leg (4) is formed of an elongate member which at its first end is pivotally attached to the chassis (7) of the trailer (2). In between each support leg (4) and the chassis (7) there is fitted a cylinder (5) so that the support leg can be turned by means of the cylinder. Each pair of support leg and cylinder (4, 5) is at its first ends pivotally attached to the rear of the trailer (2), in connection with the chassis proper (7), in between the rear bar (14) and the cross bar (15), in the longitudinal direction of the trailer (2) and at a distance (a) from each other. The second end of the cylinder (5) is pivotally attached to the second end of the support leg (4). The length of the cylinder (5), with the piston (6) retracted, and the length of the support leg (4) roughly correspond to the distance (a) of the coupling points of the first ends thereof from each other.</p> |
