The invention relates to a system for localizing an attachment tool for a work device comprising a first communication unit connect to an attachment tool and having a first acceleration sensor that is configured to provide a first acceleration signal relating to an instantaneous acceleration of the attachment tool; a second communication unit connected to the work device in the region of a connection region for the attachment tool and having a second acceleration sensor that is configured to provide a second acceleration signal relating to an instantaneous acceleration of the connection region; and an identification module that is coupled to the first and/or second communication unit(s) and that is configured to obtain the first and second acceleration signals and to enable a safe allocation of the attachment tool to the work device by evaluating the signals. The invention further relates to a set of a work device and an attachment tool having a system in accordance with the invention and to a method of localizing an attachment tool for a work device with the aid of a system in accordance with the invention.

A monitoring system for a work vehicle having a lift system to which an implement is attachable via a connection assembly includes a weight detection subsystem operable with the lift system and configured to transfer signals representative of a weight supported by the lift system. The monitoring system also includes a position detection subsystem operable with the connection assembly and configured to transfer signals representative of a state of the connection assembly. A controller is in operable communication with the weight detection subsystem and the position detection subsystem and is configured to receive signals from the weight detection subsystem and from the position detection subsystem, determine a condition of the connection assembly based on the signals received, and output a signal based at least in part on the determined condition.

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.

Power machine bucket implements include a rear wall structure, a bottom wall structure adjoining the rear wall structure at a bend region, and a two-piece brace. The two-piece brace includes a first piece attached to and extending along a portion of the bottom wall structure and a second piece, separate from the first piece, attached to the back side of the rear wall structure.

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.

A work-tool mounting mechanism detachably attaches a predetermined work tool that includes an engaged portion including an engagement hole. The mechanism includes: an engaging portion that engages the engaged portion and includes; a lever that is rotatably attached to the engaging portion; a lock pin that is movable between a locked position and an unlocked position, the lock pin being inserted into the engagement hole in the locked position, and not inserted into the engagement hole in the unlocked position; and a linking tool that moves the lock pin between the locked position and the unlocked position with a rotation of the lever. The linking tool includes a regulating portion that regulates the lock pin at the locked position from moving to the unlocked position.

A dipper handle includes a dipper tube, a dipper engagement member, and an intermediate member between the dipper tube and the dipper engagement member. The dipper tube has a substantially cylindrical outer surface and a contoured inner surface. The contoured inner surface results in multiple wall thicknesses for the dipper tube, including a first thickness proximate a first end and a second, larger thickness, proximate a second end. The second end is configured for coupling to the intermediate member.

Measure-up processes described herein provide data that enable three-dimensional (3D) positioning of a tip of a bucket of an excavator. The processes may include steps of curling a bucket of the excavator in and out, moving a stick of the excavator in and out, and moving the bucket so that it touches a point at different bucket angles. During each of the steps, data is generated using a tilt compensating survey pole and one or more inertial measurement units (IMUs).

A coupler cylinder is driven between a locked state and an unlocked state of a bucket by being supplied with hydraulic oil. A main pump supplies the hydraulic oil to the coupler cylinder. A pressure increasing valve controls the supply of the hydraulic oil to the coupler cylinder. A controller controls drive of the pressure increasing valve. The controller instructs the pressure increasing valve to stop the supply of the hydraulic oil to the coupler cylinder based on pressure in an oil passage between the main pump and the coupler cylinder.

A distance calculation unit calculates a first distance that is a distance between a first bucket point being a point on a bucket and a target design surface representing a target shape of an excavation target. The distance calculation unit calculates a second distance that is a distance between the target design surface and a second bucket point. The second bucket point is on the bucket on a straight line passing through the first bucket point and is parallel to an edge of the bucket. A tilt control unit compares the first distance and the second distance to calculate a tilt control amount to rotate the bucket around a tilt axis.
