摘要： An earth levelling blade assembly for mounting on the lift arms of a loader includes a laterally extending main blade and two shoes supported at opposing ends of the main blade for sliding engagement along the ground. The shoes are supported for movement between a forward position ahead of the main blade and a rearward position behind the main blade, as well as being adjustable in height relative to a bottom cutting edge of the main blade. A coupling arrangement between a first mounting frame on the lift arms of the loader and a second mounting frame on the rear mounting face of the main blade (i) supports the second mounting frame to be freely pivotal about a forward axis relative to the first mounting frame in which the forward axis is oriented in the forward working direction of the loader and (ii) supports the second mounting frame to freely translate relative to the first mounting frame along an upright axis.

摘要： An assembly for an excavator includes a bucket having coupling flanges spaced apart from each other. The coupling flanges extend upwardly from a top wall of the bucket and laterally between side plates of the bucket. Each coupling flange has an aperture. The assembly also includes a linkage assembly coupled to the bucket and configured to tilt the bucket relative to an arm of the excavator. The linkage assembly includes: a top mount configured to be fixedly releasably coupled to the arm of the excavator; a shaft fixedly coupled to the top mount and received in each of the apertures such that the bucket is pivotally coupled to the shaft; a drive lug coupled to and depending from the shaft between the coupling flanges; and a linear actuator coupled to the bucket and the drive lug to pivot the bucket about the shaft.

摘要： A method of extending a reach of a material mover may include uncoupling and removing a first linkage that couples a work implement to an actuator on the material mover; uncoupling the work implement from one or more lifter arms; securing one or more extensions to each of the one or more lifter arms by (a) fastening, with a first fastener, an extension to a corresponding lifter arm, though a lifter-arm retention aperture, and (b) further securing the extension to the corresponding lifter arm with one or more additional fasteners adjacent the lifter-arm retention aperture and a top edge or bottom edge of an end of the corresponding lifter arm; coupling the work implement to the one or more extensions; and coupling a second linkage, which is longer than the first linkage, to the work implement and to the actuator.

摘要： A main controller controlling an operation of a work vehicle includes a determination unit and an abnormal condition determination unit. The determination unit determines whether or not an attachment has a sensor based on information on an attachment. When the determination unit determines that the attachment has the sensor and when the abnormal condition determination unit cannot receive a signal from the sensor, the abnormal condition determination unit determines that an abnormal condition has occurred.

摘要： A control system controls a construction machine that includes a work machine including a bucket having a plurality of tilting mechanisms. The control system includes: a tilt angle sensor that is provided in the bucket so as to detect tilt angle data including a rotation angle of the bucket about the tilt shaft, the tilt angle sensor being capable of detecting an inclination angle with respect to a horizontal plane; a data acquisition unit to which the tilt angle data is output from the tilt angle sensor; a data fixing unit that fixes the tilt angle data output to the data acquisition unit based on a fixing command to generate fixed data; and a work machine control unit that controls the work machine based on the fixed data until the fixing command is disabled.

摘要： An excavator comprises a chassis, an implement, and an assembly comprising a boom, a stick, and a coupling. The assembly is configured to define a heading {circumflex over (N)} and to swing with, or relative to, the chassis about a swing axis S. The stick is configured to curl relative to the boom about a curl axis C. The implement is coupled to a stick terminal point G via the coupling and is configured to rotate about a rotary axis R such that a leading edge of the implement defines a heading Î. An excavator control architecture comprises sensors and machine readable instructions to generate signals representative of {circumflex over (N)}, an assembly swing rate ωS about S, and a stick curl rate ωC about C, generate a signal representing a terminal point heading Ĝ based on {circumflex over (N)}, ωS, and ωC, and rotate the implement about R such that Î approximates Ĝ.

摘要： A tilt bucket may include a front structure having an outer surface, the front structure including a base plate with a bottom surface. The tilt bucket may include a bottom edge and a curved wrapper extending between the base plate and the bottom edge. A ratio of a maximum distance between the curved wrapper and a first line extending from the bottom edge to the tangent point on the outer surface of the front structure, taken substantially perpendicularly from the first line, relative to a length of the first line, may be about 0.64 to 0.70.
