A quick coupler for coupling a tool such as an excavator bucket, a clamshell grapple or demolition shears to a tool operator such as an excavator arm or the like. The quick coupler including a coupling mount for receiving a first locking part and a locking mount for receiving a second locking part, wherein a locking element for locking the second locking part in the locking mount is at least associated with the locking mount, with the locking element being actuable by an adjustment actuator. The quick coupler can be electrically controllable, with the quick coupler having an electric drive for actuating the adjustment actuator for the locking element.

A coupler for securing an attachment to an earth working machine. The coupler comprises 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 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.

A pin grabber coupler and method for locking and unlocking a tool to a machine is disclosed. The pin grabber coupler may comprise a tertiary lock configured to pivot between an unlocked TL position and a locked TL position. The tertiary lock may include a first and second shoulders, a leg, a tab, a latch, a bias member and a detent. The bias member may be configured to exert a biasing force on the tertiary lock to urge the tertiary lock to the locked TL position. The detent may be configured to exert, when in a hold position, a holding force against the latch that is greater than the biasing force exerted by the bias member. When the detent is in a release position, the holding force applied by the detent against the latch is less than the biasing force applied by the bias member.

A system for connecting an implement to a machine. A universal adapter to connect implements with machines. A frame with brackets on one side to couple to lift arms and tilt operators on a machine such as an earthmoving vehicle. Brackets on the other side of the frame to detachably couple to the implement. A locking mechanism on the frame with operative handles to engage locking pins on the adapter with the implement between a release and locked position.

A modular thumb for a bucket of an excavator arm having a thumb body rotating with respect to the excavator arm. The thumb body has a pair of spaced elongate members and a main body extending between the elongate members. The main body has a bucket side and a non-bucket side. A channel on the non-bucket side and along the elongate members receives at least one of: an actuating arm of a progressive link kit and an actuator of the excavator arm. A tine kit may be welded to the main body.

A pin grabber coupler for coupling an attachment with an excavator having a housing at least between the plates; a rear receiving arch and a forward receiving arch formed by the spaced-apart plates for receiving a pin of the attachment; a wedge lock extending between the spaced-apart plates; and a main actuator driving the wedge lock into the rear receiving arch and retracting the wedge lock from the rear receiving arch. A locking system for locking or unlocking the wedge lock has a latch having a latch end, a lever end, and a pivot therebetween; the latch end engaging the wedge lock once the wedge lock is fully extended into the rear receiving arch; a biasing member coupled to the lever end and biasing the latch end towards the wedge lock; and an unlock actuator opposing the biasing member to disengage the latch end from the wedge lock.

A quick coupler and methods of coupling and decoupling a quick coupler and work tool are disclosed. The quick coupler includes a frame, cylinder, primary blocking member, secondary blocking member, biasing member, and controller. The method of coupling includes activating an AUTOMATIC LOCKING state, automatically locking a second tool pin within a hook, a first tool pin entering a notch, and activating a LOCKED state. The method of decoupling includes activating the AUTOMATIC LOCKING state, resting the work tool on a surface, activating an UNLOCKED state, and separating the quick coupler and work tool. Advantageously, the quick coupler can automatically lock the second tool pin without actuation of the cylinder.

The present invention provides a coupling apparatus for coupling an attachment to a dipper arm of a machine. The apparatus includes a coupler body; a first, fixed engaging means mounted on the coupler body for engaging a first coupling pin of the attachment, in use; a latch member associated with and pivotable with respect to the first, fixed engaging means between latched and unlatched positions; and a locking member pivotable about a pivot point between first and second positions, and provided in mechanical communication with the latch member. The latch member includes an aperture located therethrough, and the locking member includes a trunnion member or other such protrusion located thereon, extending into or through the aperture of the latch member and engaging the same such that when the locking member is in the first position, the latch member is in the latched position, and when the locking member is moved to the second position, the trunnion member moves the latch to the unlatched position.
