Abstract
A loader arm assembly is configured to rotate about an axis defined by a pivot pin. The loader arm assembly includes a loader arm having a first end and a second end, the first end having a cavity. The cavity is configured to be aligned with an axis of rotation. The cavity has a cavity perimeter. The loader arm assembly further includes a pivot tube assembly including a pivot tube having an inner bore configured to engage a pivot pin for rotation about the axis. The pivot tube further has an outer perimeter. A portion of the outer perimeter fixedly engages the cavity perimeter. The pivot tube assembly further includes one or more plates extending from the pivot tube in fixed parallel engagement with the loader arm.
Claims18
A loader arm assembly configured to rotate about an axis defined by a pivot pin, the axis being substantially normal to the loader arm, the loader arm assembly comprising:
- a loader arm having a first end and a second end, the first end having a cavity including a cavity perimeter, wherein the loader arm includes substantially parallel first and second side portions and a central portion joining the first and second side portions, the first and second side portions being substantially normal to the axis;
- and
- a pivot tube assembly including a pivot tube having an inner bore configured to engage the pivot pin for rotation about the axis, the pivot tube further having an outer perimeter, a portion of the outer perimeter fixedly engaging the cavity perimeter, the pivot tube assembly further including one or more plates extending from the pivot tube between the first and second side portions and in fixed engagement with at least one of the first and second side portions of the loader arm.
An assembly configured for rotation about an axis defined by a pivot pin, the assembly comprising:
- an arm having a first end and a second end, the arm having a cavity at the first end, wherein the arm comprises a first substantially flat side wall and a second substantially flat side wall, the second side wall being substantially parallel to the first side wall, the first and second side walls being substantially normal to the axis;
- and
- a pivot tube weldment including a pivot tube rigidly fixed within the cavity and at least one plate extending from the pivot tube between the first and second side walls, at least one plate welded to the pivot tube and at least one of the first and second side walls, the pivot tube having an inner bore configured to rotatably receive the pivot pin.
