Trailer with adjustable angle comprises front coupling to tractor and two rear side by side axles, coupling pivoting about spindle with angular position controlled by actuator so as to tip and be supported on front or rear wheels

摘要

The trailer comprises a coupling (30) at the front for coupling to a tractor and at the rear two side by side axles (10,20) fixed at the same height under the trailer. The front coupling pivots about a transverse spindle (31) parallel to the axles. An actuator (51) controls the angular position of the trailer relative to the coupling so that the trailer can tip to be supported on a pair of front wheels (11) or on a pair of rear wheels (21).
