摘要： A specially designed quick coupler is representatively used to removably attach an excavation bucket to the outer boom end of an excavator. A top portion of the quick coupler is pinned to the outer boom end and has a bottom portion with spaced apart recesses configured to releasably receive portions of stick and curl pins on the bucket. An arcuate latch hook is translationally drivable by a hydraulic cylinder assembly toward one of the implement pins to releasably lock it in its associated coupler recess in a manner also captively retaining the other implement pin in its associated coupler recess. Stop structures oppose the latch hook and, using a simple shim arrangement, may be translationally shifted toward and away therefrom to easily adjust the coupler for wear and/or changes in the implement pin spacing. A redundant safety system is incorporated in the coupler and serves to hold the latch hook in its locking position. The safety system includes hydraulic and mechanical locking mechanisms and a spring structure resiliently biasing the latch hook toward its locking position.

摘要： The present invention includes a coupler assembly connected between a standard bucket and a work machine. The coupler assembly converts the standard bucket to a side dump bucket. The conversion is possible through the use of a pivot assembly and actuating device. The pivot assembly includes an interface portion that is releasably connected to the work machine and a base portion. The base portion is pivotably and releasably connected with the interface portion via pins. The actuating device is connected between the interface portion and the base portion. The removal of one of the pins allows for the pivotable movement of the base portion outwardly and laterally via the actuating device to establish an angular relationship between the bucket and the work machine for dumping material within the bucket to one side of the work machine. Additionally, the coupler assembly is designed so that the actuating device may be easily relocated so that pivotable movement of the base portion allows material within the bucket to be dumped to another side of the work machine opposite the one side.

摘要： An excavating implement which includes a blade defining a top surface, an opposed bottom surface, a rear edge, a front edge, and opposed end surfaces. Primary cutting edges are spaced apart along the front edge, and secondary cutting edges positioned between the primary cutting edges. The secondary cutting edges are recessed relative to the primary cutting edges. The secondary and primary cutting edges intersect with the bottom surface. The blade also defines primary and secondary beveled surfaces forming acute angles with the bottom surface, and which extend angularly toward the rear edge from the respective primary and secondary cutting edges to intersect with the top surface.

摘要： A lift structure for a work vehicle including a pair of lift arms arranged on opposite sides of the work vehicle, each lift arm having a first end pivotally coupled to the work vehicle and a second end for coupling to a tool. Each lift arm includes a first side plate member, a second side plate member, an elongated top tubular member and a bottom member. Each side plate member has a plurality of pivot orifices including at least one pivot orifice near each end of the side plate members and at least one intermediate pivot orifice located between each end of the side plate members. The elongated top tubular member is attached between each of the parallel side plate members at the top edge so as to connect to each side plate member. A bottom member is positioned in a spaced relationship from the top member between each side member and is connected to each side member. The top tubular member provides additional strength to the side plate members to resist bending and torque loads. A traverse torque member is mounted between each lift arm and is connected to each side member of each lift arm. A material handling tool, such as a loader bucket, can be coupled to the second end of each lift arm.
