Abstract: A load cylinder for compensating unbalanced forces applied by a load. According to one implementation the load cylinder comprises a hollow ring-shaped body, a base fixed to a first end of the ring-shaped body, and a rod housed partially in the hollow space of the ring-shaped body, a chamber being delimited between side walls of the ring-shaped body, the rod and the base. The rod is housed partially in the chamber and may move in its interior. The rod comprises a housing on one end, and the load cylinder comprises a compensation member housed in the housing, the compensation member being acted on to cause the movement of the rod. The housing comprises a greater width than the width of the compensation member, with the result that the compensation member may move inside the housing.
