Grue amelioree pour soulever et transporter des charges

Improved crane for lifting and transporting loads

Abstract

The crane (10) for lifting and transporting loads comprises: a base frame (12), capable of transferring the loads of the crane (10) onto a support surface; a sliding element (16) which is constrained to the base frame (12) in a sliding manner; an arm (18), capable of moving the loads hinged to the sliding element (16); a connection element (20) having a first end, which is hinged to the sliding element (16), and a second end, which is constrained to the base frame (12) in a mobile manner; a pair of rod elements (22). Each rod element (22) is hinged to the base frame (12) and to the connection element (20) so as to form an articulated quadrilateral. The crane (10) comprises, furthermore: a first linear actuator (24), hinged to the base frame (12) and to the connection element (20) and capable of causing the sliding movement of the sliding element (16) relative to the base frame (12); and a second linear actuator (26), hinged to the sliding element (16) and to the arm (18) capable of causing the mutual rotation movement between the arm (18) and the sliding element (16).
