Rolling device allowing optimal distribution of the load and levelling in banking, the invention relates to a hydraulic device which can be applied to trailers having at least two axles. The device consists of axles with independent wheels comprising the axles, the suspension arms (2) and the thrust cylinders (4). The thrust cylinders which are on the same side of the trailer are joined together by pipework (7) (8). The oil flowing freely between each thrust cylinder allows flexibility in the movement of each suspension arm, allowing the weight to be distributed over each wheel. The hoses (9) joining the thrust cylinders on each side of the trailer to the hydraulic take-offs of the tractor make it possible to lower or to raise the two sides of the trailer independently, which allows levelling on banked ground, as well as allowing the two sides to be lifted. This device is intended for agricultural and industrial trailers. <IMAGE>
