Patent ID: 8764059

Claim:
A self-moving operating machine with integrated lateral movement and leveling device, including: a chassis having a front part and a rear part to which a fore axle, provided with a pair of wheels, and a rear axle, provided of a pair of wheels, are constrained, respectively; an operating arm having a related end constrained to the rear part, such as to be movable in a vertical plane of the latter; another end of the operating arm being free and designed to carry a tool, characterised in that: the front part and the rear part are articulated to each other by a coupling that allows relative movements about at least one articulation axis; said front part also being constrained to said rear part through a deformable four-arm linkage, in which two opposite members, formed jointly by the front part and the rear part, are linked to each other via two actuators, each of which is connected, connecting rod-wise, with a related end to the front part and, with the other end, to the rear part; said actuators being designed to operate in mostly vertical directions; at least a third actuator being provided which is connected, connecting rod-wise, with a related end to the front part and, with the other end, to the rear part and which is designed to operate according to mostly horizontal directions; said actuators being independently operable; means being provided which are designed to measure loads weighing on at least one of the two wheels of the above mentioned fore axle and to impart a locking command in response to predetermined limits being achieved, to lock said rear axle with respect to the related rear part.
