Abstract
A working machine includes a support, and a moveable material handling assembly having a working arm mounted at a first pivot and configured to be mounted to a material handling implement at a second pivot. A pivoting mechanism is mounted to the implement at a third pivot and includes a Z bar link, a chassis link, and an actuator. The Z bar link mounts to the working arm at a fourth pivot and the chassis link mounts to the Z bar link at a fifth pivot and mounts to the support at a sixth pivot. The actuator is mounted to the Z bar link at a seventh pivot, and the fourth is pivot between the fifth and seventh pivots. The implement pivots relative to the working arm about the second pivot via pivoting the arm relative to the support about the first pivot.
Claims20
A working machine comprising a support, and a material handling assembly movable relative thereto, the material handling assembly comprising:
- a working arm pivotally mounted to the support at a first pivot, and configured to be pivotally mounted to a material handling implement, such as a shovel, at a second pivot;
- and
- a pivoting mechanism configured to be pivotally mounted to the implement at a third pivot, and comprising:
- a Z bar link;
- a chassis link;
- and
- a first actuator operable to extend and retract,
- the Z bar link pivotally mounted to the working arm at a fourth pivot,
- the chassis link pivotally mounted to the Z bar link at a fifth pivot,
- the chassis link pivotally mounted to the support at a sixth pivot, and
- the first actuator pivotally mounted to the Z bar link at a seventh pivot,
- wherein the fourth pivot is interposed between the fifth and seventh pivots,
- wherein the pivoting mechanism is configured to pivot the implement relative to the working arm about the second pivot via pivoting of the working arm relative to the support about the first pivot, and via operation of the first actuator, and
- wherein the pivoting mechanism is interposed (e.g. substantially centrally) between opposing lateral ends of the working arm.
