ARTICULATING SUPPORT FOR CONSTRUCTION MACHINE CONSTITUTING A QUICK-RELEASE FASTENER AND RELATED MANUFACTURING METHOD

摘要

An implement attachment is coupled to a working arm of a working machine. The arm is connected to an implement attachment by fastener sleeves and fastener pins. The attachment includes two side plates, each carrying two bushes having holes for accommodating the fastener pins. The bushes have a circular guide portion fitting into a circular hole in respective side plates. Each bush has a flange connected to the side plates by a fastener. The hole receiving the fastener pins is eccentric to the guide portion with respect to at least two of the bushes. As a result, the implement attachment is readily mounted on mutually different working arms.
