A linkage system for making an equipment translate parallely to itself, such equipment being carried by an excavator or by a basic machine

摘要

A linkage system (12) connects an equipment (11) and an excavator or a basic machine (10) by which such linkage is carried. The linkage is quadrilateral so as to translate said equipment (11) parallely to itself and it consists of at least one rigid element (13) connecting the machine (10) and the equipment (11) and at least one piston actuator (15) for said rigid element (13). The elements forming the linkage system (13,14,15,40) or part of them are connected with the machine (10) by no more than two separate and substantially parallel hinge axles (22,23).
