Disclosed embodiments include power machines, implement coupling systems and methods in which hydraulic or electric coupling between an implement and the power machine is made automatically using an existing actuator, for example a tilt actuator, of the power machine. Thus, additional actuators are not required to achieve hydraulic or electric coupling. In exemplary embodiments, power coupling is also free from the process of mechanically coupling the implement to the implement carrier. Also, in exemplary embodiments, a machine side coupler assembly moves with the implement after a connection is established, despite the implement coupler assembly being removed from the implement carrier. This allows the same implement carrier to be used on all similarly sized machines.

A quick coupler (1) for attaching a tool (2), comprising an attachment bracket with two parallel attachment pins (3a, 3b), to an earth moving vehicle, where the quick coupler (1) comprises a frame (4) with a first cutout (5) and a second cutout (6) arranged substantially perpendicular to each other, which are adapted to cooperate with the respective attachment pin (3a, 3b) of the tool (2). The quick coupler (1) further comprises at least one, in relation to the frame (4) moveable locking arrangement (9), adapted to delimit the second cutout (6) in a direction parallel to the first cutout (5), whereby one of the attachment pins (3aq, 3b) of the tool is locked in the second cut-out (6) and at least one locking segment (18a, 18b) arranged to be rotated in relation to the frame (4) in at least a first and a second direction between different positions, whereby the locking segment (18a, 18b) in at least one position delimit the first cut-out (5) and locks the second of the attachment pins (3a, 3b) of the tool.

A tool holder includes a locking cylinder provided with two first gripping pins extending laterally from each side of the fixed part thereof, and two second gripping pins extending laterally from each side of the moving part thereof. The tool includes at least two reception assemblies each having a first receiving portion and a second receiving portion the openings of which are each facing and provided to receive one of the first gripping pins and one of the second gripping pins for retaining the tool on the tool holder. The tool is locked on the tool holder by means of the locking cylinder by moving each gripping pin into abutment at the bottom of the associated receiving portion thereof.

A quick hitch for coupling and decoupling a tool at a rotator for rotating the tool that has a rotator attachment part that is attachable to an excavator arm or the like and that has a rotary rotator part rotatable relative thereto, wherein the quick hitch has a coupling part at the rotator side that is fastenable to the rotatable rotary rotator part and has a coupling part at the tool side, wherein the two coupling parts can be brought into engagement with one another and can be latched to one another by at least one latch element. A latch operating actuator is provided at the rotator attachment part for actuating a latch adjustment part movably arranged at one of the coupling parts for the unlatching and/or latching of the latch element, the latch operating actuator being rotatable about the rotator axis of rotation relative to the latch adjustment part.

A quick coupler which features a safety mechanism which facilitates ease of use and assures safe use in the workplace by use of hydraulic circuits designed to automatically reset the safety locking mechanism on intentional removal of a front pin, including use of a 2-line hydraulic supply to the coupler.

A coupling assembly for releasably mounting, and hydraulically coupling, a tool to a work machine. The coupling assembly includes a mount attachable to the work machine and configured to receive the tool in a mounted position of the tool, a rigid retaining body movable in translation relative to the mount along a translation axis between a retaining position for retaining the tool to the mount and a release position for releasing the tool from the mount, a first and a second actuator operable to move the retaining body between the retaining and release positions, and a hydraulic coupling manifold movable in translation relative to the mount along the translation axis for hydraulically coupling the tool to the machine, wherein the hydraulic coupling manifold uses the first and second actuators as guides for moving along the translation axis.

The coupler is mounted on the end of the boom of a boom-tractor, and provides secure locking-in of a bucket. The coupler having been set to its latched-open condition, the tractor is driven to the bucket so that the bottom-lug of the bucket enters the coupler, whereupon the bucket is picked up and is automatically securely locked into coupler, without and manipulation of the coupler being required of the tractor-driver other than manipulation of the boom. For setting the bucket down on the ground, after use, the driver manually pulls out a slider of the coupler. That action sets the coupler into its slider-held condition, whereby when the tractor is driven away from the bucket, the coupler is automatically left set in the said latched-open condition.

The present invention is related to a coupler for detachably coupling to a work tool is provided. The coupler includes a frame with a first aperture formed therein. The first aperture extends along a first axis inclined with respect to a transverse axis of the frame. The coupler further includes a first locking member provided within the first aperture. The coupler also includes an actuator configured to move the first locking member between an unlocked position in which first locking member is disengaged from the work tool, and a locked position in which the first locking member is engaged with the work tool.

A tool coupler assembly may include a power linkage assembly, and the power linkage assembly may include a first power link. The first power link may include a first end configured for pivotal connection to a tool, and a second, opposite end configured for pivotal connection to one end of a tool control actuator. The tool control actuator may be connected at an opposite end to a first end of a tool support member of a machine, wherein operation of the tool control actuator pivots the tool about a tool pivot axis coaxial with a tool engagement interface at a second end of the tool support member. A power linkage actuator may be pivotally connected at a first end for coaxial rotation with the tool engagement interface at the second end of the tool support member, and at a second end for coaxial rotation with the first end of the first power link.

A coupler for securing an attachment to a machine is provided. The coupler includes a front portion configured to receive an attachment and a rear portion configured for coupling to lift arms and a tilt linkage of a machine. The front portion and rear portion being defined by an upper and lower cross-members, first and second side members, and a center portion. Each of the first and second side members has a plate configuration and an intersection of the inner surface of each of the first and second side members and a lower surface of the upper cross-member forms a substantially 90° angle with first and second window openings defined between the rear portion and the front portion.
