Implement coupling for a loading machine

摘要

There is disclosed an implement coupling (2) for a loading machine including connecting means (8) arranged for mounting the implement coupling (2) at the distal end of a loading arm (60) and for connecting with an actuating arm of a hydraulic cylinder, the implement coupling (2) comprising coupling means (12,18) adapted for coupling the implement coupling with complementary coupling means (14,16) of an implement (62), e.g. a loading bucket, and a locking mechanism (20,22) with a transverse, displaceable locking beam comprising locking means (20) adapted for interacting with the complementary coupling means (14,16) of the implement (62), and which may be displaced by means of a pivot mechanism (28,32,34) and/or a number of spindles or a number of hydraulic cylinders (54), where the coupling means (12,18) are constituted by upper fixed hook coupling parts (12), which are arranged for gripping around upper connecting pins (14) on the implement (62), and by lower, displaceable hook locking parts (20), which are arranged for fixing lower connecting pins (16) of the implement (62) when these are in contact with a contact surface on the implement coupling, the displaceable locking parts (20) being connected with the locking beam (22).
