The present invention describes a quick hitch for coupling a tool to an excavation arm of an excavator. The quick hitch comprises a connector comprising a first end coupleable to an excavation arm, and a second end coupleable to a tool; and a latching member releasably engageable with the second end of the connector. In use the second end of the connector receives the tool, and the latching member engages with the connector to releasably couple the tool to the connector.

A work implement of a motor grader in which a blade can readily be replaced is provided. The work implement includes a shift cylinder assembly and a blade. The shift cylinder assembly includes a blade shift cylinder and a rail which carries out reciprocating motion with extending and retracting of the blade shift cylinder. The blade is removably attached to the shift cylinder assembly. The blade includes a hook and the shift cylinder assembly includes a hook reception portion. The hook is hooked on the hook reception portion.

A quick-hitch for coupling a tool to an excavator arm or a similar tool manipulator includes two hitch halves that can be latched together, coupled to one another at a first pair of latching parts, and pivoted together, about the coupled first pair of latching parts, into a coupling position in which a second pair of latching parts of the hitch halves can be latched. Energy coupling parts are provided on and a coupling carrier is attached to each of the two hitch halves.

A coupler for a work machine that has a first coupler hook pin defined along a hook pin axis, a first coupler engaging pin defined along a first axis, a second coupler engaging pin defined along a second axis, the second axis being different from the first axis. Wherein, the first coupler engaging pin is coupleable to a first device and the second coupler engaging pin is coupleable to a second device.

A front loader includes a working tool and an attachment body to which the working tool is attached, including a lock pin configured to attach and fix the working tool, a lock lever configured to move the lock pin between a releasing position and an attaching position, and a latching portion having a retaining mechanism configured to retain the lock lever at the releasing position and another mechanism configured to move the lock lever to the attaching position.

There is described a coupler for removably coupling to an excavation tool having a pair of brackets, each bracket having longitudinally spaced-apart first and second coupling notches defined therein. The coupler generally has a frame extending longitudinally between first and second end portions, the frame having a pair of opposite, first coupling protrusions transversally protruding from the first end portion; a pair of opposite, second coupling protrusions being movably mounted to the frame and transversally protruding from the second end portion; and an electrical motor being mounted to the frame and being configured for selectively moving the second coupling protrusions along a longitudinal orientation between an open position allowing engagement between the coupler and the excavation tool, and a closed position, in which the first and second coupling protrusions are pressingly engaged against respective first and second coupling notches, thereby maintaining the coupler fixedly coupled to the excavation tool.

A coupler for a wheel loader is disclosed. The coupler is used for coupling an attachment to a lifting arm of the wheel loader. A bracket is installed between the lifting arm and the attachment. The bracket's back face is pivotally connected to a lifting arm and the bracket's front face is detachably connected to the attachment. The attachment has a pair of protrusions rearwardly extending from the lower back of the attachment and have locking holes pierced through their width. The bracket has a pair of receiving slots formed at the lower front of the bracket and engaged with the protrusions. The coupler has a shaft, and a pair of locking pins combined with the shaft by threads. The threads formed at one end of the shaft are right handed and the threads formed at the other end of the shaft are left handed. When users turn the shaft in one direction, the locking pins are extended and engaged with the locking holes (a coupling position). When users turn the shaft in the other direction, the locking pins are shortened and released from the locking holes (a release position).

There is disclosed a lifting apparatus and a method for lifting a shovel including its upper part, its lower part, and its boom while the shovel handle and dipper remain on the ground. The lifting system may comprise six lifting devices arranged in three pairs that are disposed under the shovel on three lines: front, middle and rear, the rear line being under the shovel counterweight. The lifting system is connected to a power and control unit from which, through the use of a programmable logic controller and level detectors, metered hydraulic power is selectively applied at each lifting point in order to raise the shovel to a desired height while in doing so maintaining it level with a pre-set lifting plane throughout the entire operation.

Carrier vehiclessuch as, for example, front loadersare configured to operated with one or more interchangeable implements that are selectively coupled to the carrier vehicle by driving the carrier vehicle towards a desired implement and aligning the implement attachment points with corresponding attachment points on an implement mount that is attached to the carrier vehicle. In some cases, the operator's view of the various attachment points (catch hook and support pins, rods, lines) of the implement and the implement mount is blocked by the front loader arms (booms) or other components of the carrier vehicle. Systems and methods are presented herein for aligning the carrier vehicle with the implement using marks/indicators that are visible by the operator of the carrier vehicle.

The present invention provides a reversible bucket coupler device and method of use for reversing the orientation of a bucket used with an excavator so that the teeth of the bucket is facing away from the cab of the excavator and method of use. The reversed orientation of the bucket using the reversible bucket coupler device provides an operator of an excavator the ability to complete tasks in a more efficient, clean and safe manner, as well as providing much needed flexibility in the way excavation projects can be performed.
