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.

A bucket height notification device includes a bucket height specification unit and a bucket height notification unit. The bucket height specification unit specifies a bucket height from a ground surface to a bucket of work equipment included in a work vehicle related to remote operation. The bucket height notification unit notifies of the bucket height.

A dipper handle assembly includes a tube coupled to a yoke. The yoke has a collar extending along a collar axis, a transition portion, a first arm and a second arm. The transition portion includes a distal end having first and second lateral sections and first and second transverse sections. The first and second lateral sections and the first and second transverse sections all lie in a virtual transition portion distal end plane, and the virtual transition portion distal end plane intersects the collar axis at an oblique angle.

A ground engaging tool locking system includes a pin having a first, proximal head region and a second, distal end region spaced from the first, proximal head region along an axis. The pin includes a groove located between the first, proximal head region and the second, distal end region. A biasing element is disposed at least partially within the groove.

A skip pan for handling materials comprising a base of the skip pan for containing the materials. A portion of a contour thereof has walls and a remainder of the contour is a wall-less edge. A bridge holds the base and comprises, at the top, a connecting portion for connecting to an arm of a material handler. The connecting portion is rotatable along a vertical axis thereof to provide a spinning movement to the skip pan. The connecting portion is tiltable by the arm of the material handler. An actuator provides an adaptable inclination of the base of the skip pan with respect to the bridge to keep the base balanced when the connecting portion is tilted to avoid contents to slide by the wall-less edge during movement.

A multi-pulse transformer for an industrial machine, the multi-pulse transformer including a primary winding configured to receive a first voltage from a power source via a transformer, and a plurality of secondary windings configured to output a second voltage to a converter, the second voltage less than the first voltage. Wherein the multi-pulse transformer attenuates harmonic distortions by phase shifting each one of the plurality of secondary windings with respect to the primary winding. Wherein the multi-pulse transformer provides bi-directional flow of power.

A dipper for a work machine is disclosed. The dipper may have a front cavity wall forming an inlet which defines a vertical inlet plane, a rear cavity wall opposite the front cavity wall forming an outlet which defines an outlet plane, a top cavity wall extending between front and rear cavity walls defining a horizontal top plane, a bottom cavity wall opposite the top cavity wall defining a bottom plane, and two side cavity walls. The two side cavity walls may further extend between the front and rear cavity wall. The outlet plane may be angled relative to the inlet plane, the bottom plane may be angled relative to the top plane, and the outlet plane is perpendicular to the bottom plane.

A coupler assembly for detachably coupling an arm to a work tool. The coupler assembly comprises a first linkage having an idle link and a power link, a first pin provided on the arm, and a second pin provided on the power link. The first and second pins are receivable in openings on the work tool. The coupling assembly is characterized by a second linkage provided between the first and second pins comprising a first link and a second link joined at a shaft. The first link is fixed to the shaft to prevent rotation therebetween. A portion of the shaft comprises a gear. The second link comprises a body mounted on the shaft so as to be rotatable thereabout, the body comprising a chamber in which a piston is received, the piston including a geared section that is meshed with the gear.

A connection switching device (45) connects a bottom-side oil chamber (15C) of a boom cylinder (15) and a bottom-side oil chamber (16C) of an arm cylinder (16) when a boom operating device (22A) instructs the contraction of the boom cylinder (15) and an arm operating device (21B) instructs the expansion of the arm cylinder (16). The connection switching device (45) connects the bottom-side oil chamber (15C) of the boom cylinder (15) and a rod-side oil chamber (16D) of the arm cylinder (16) when the boom operating device (22A) instructs the contraction of the boom cylinder (15) and the arm operating device (21B) instructs the contraction of the arm cylinder (16).

A system for detecting carryback within a dump body of a haul truck may include at least one camera and at least one controller. The at least one camera is configured to generate a scan of an interior surface of the dump body. The at least one controller is configured to receive the scan of the interior surface of the dump body and determine a type of dump body by comparing the scan of the interior surface of the dump body with at least one scan of an interior surface of a known dump body.
