Abstract

A wedge locking element (10) for a locking device of a quick coupler A for coupling the pin P2 of an attachment to earth working machinery. The wedge locking element (10) has a sloping wedge surface (13). Projecting from the wedge surface (13) is an engagement surface (12) with which the attachment pin P2 can engage but not apply any substantial driving force to the wedge locking element (10) in the event of failure of a force maintaining the wedge locking element (10) in a position where the pin P2 is retained with the coupler A. The pin engagement surface (12) lies in a plane that is substantially in line with the direction in which the locking element (10) is, in use, moved by the driving force.

Abstract

A coupler for securing an attachment to an earth working machine. The coupler Includes a coupler body that presents a receptacle having a capture region. A pin of an attachment can move into and out of the capture region. A retainer can capture the pin in the capture region but the retainer can be moved by a hydraulically driven driver to a position to allow release of the pin from the capture region. A trigger that the pin will strike when the pin moves into or out of the capture region, decouples the driver from the retainer and the retainer is then allowed to be biased back to its retaining position by a spring.

Abstract

Quick couplers release one attachment and quickly attach another attachment to the end of the arm. Different attachments are available with differing widths. The attachments comprise of a front and a back pin that are able to engage with the quick coupler. The front pin and/or the back pin are preferably presented mounted to side plates that are secured to the bucket of the attachment. The spacing between the side plates may vary from attachment to attachment. The present invention is a packer that is able to engage with a quick coupler so as to prevent slop when attachments narrower than the quick coupler are used.

Abstract

A wedge locking element (10) for a locking device of a quick coupler A for coupling the pin P2 of an attachment to earth working machinery. The wedge locking element (10) has a sloping wedge surface (13). Projecting from the wedge surface (13) is an engagement surface (12) with which the attachment pin P2 can engage but not apply any substantial driving force to the wedge locking element (10) in the event of failure of a force maintaining the wedge locking element (10) in a position where the pin P2 is retained with the coupler A. The pin engagement surface (12) lies in a plane that is substantially in line with the direction in which the locking element (10) is, in use, moved by the driving force.

An indicator for a quick coupler for the mounting of an attachment to an earth working machine. The indicator (10) has a sensor (14,15) which, in response to movement of a movable pin engagement component (F) of a coupler (A), determines that the pin engagement component (F) will have moved sufficiently to engage and lock a pin (P2) of an attachment with the coupler (A). The indicator (10) has an indicating part (17) which is caused to be moved in response to the sensor (14,15) to thereby provide a visual indication (25) that engagement and locking of the pin (P2) has occurred.

Abstract

A coupler used for the attachment of a work tool / implement to earth moving equipment. The coupler includes a locking mechanism (10) to prevent or restrict rotational movement of an actuator element R of the coupler. The locking mechanism (10) includes an engagement element (19) that is biased into engagement with one of a plurality of spaced apart engagement areas (12). The engagement element (19) can thereby engage with an engagement area (12) and be held therewith when the actuator element R is rotatably adjusted to attach the coupler to a work tool / implement.

Abstract

A locking mechanism 10 for a quick coupler A has a movable locking element 11. A biasing element 13 is adapted to bias the locking element 11 to move in a first direction. An operator 12 is arranged to move the locking element 11 against the bias of the biasing element 13. The locking element 11 has teeth or serrations 19 which, when the locking element 11 is moved by the biasing element 13 in the first direction, is engageable with further teeth or serrations 20 coupled to a movable wedge element F of the quick coupler A to lock the wedge element 11 against movement. The movement of the locking element 11 creates a compressive force that causes the teeth / serrations 19, 20 to positively mesh and remain meshed.

Abstract

An implement pivots with respect to an earth moving or materials handling machine to which the implement is attached. The implement may be a bucket adapted to pivot laterally with respect to an excavator or other machine to which the bucket is attached. An adjustment arrangement includes a linear actuator which operates along a substantially fixed axis to drive the pivoting movement. The linear actuator may drive a rack which engages with a pinion to cause pivoting movement.

Abstract

A coupler is configured to couple an implement to an earth moving or materials handling machine. The coupler includes a locking member for locking a pin of an implement into a coupler in the recess. The locking member is driven by a hydraulic arrangement, with the hydraulic cylinder body being formed integrally with either the coupler body or the locking member. The coupler may be adapted to accommodate a range of implement pin spacings and/or diameters, so that the coupler can be used with different implements and in particular with different makes of implement.
