Abstract

The underframe consists of an upper frame 1 and another, lower frame 3 secured by means of struts 2, and in said underframe there is a transverse shaft 12 to which are secured, via their ends, respective connecting rods 11 supporting the corresponding sets of wheels 10, in such a manner that said wheels can be distanced as desired with respect to the underframe 1-3 when a pair of lateral hydraulic cylinders 15 act on arms 14 also secured to the shaft 12. Complementarily, the bar 7 of the trailer incorporates a fork 6 which is joined in an articulated manner to the crosspiece 4 of the lower half-frame, at the same time as said bar is connected to the upper frame by means of another hydraulic cylinder 9 which allows its tilt to be adjusted.
