Abstract: Engineers have been seeking strategies to improve a work machine operator's comfort and to ensure the operator's safety. The present disclosure includes an operator control station that includes a seat assembly supported, in part, on a suspension system. At least one work machine operation controller is pivotably attached to the seat assembly between an egress position and a work machine operation position. A locking mechanism is operable to fix the work machine operation controller in the work machine operation position.

Abstract: An armrest adjusting mechanism is disclosed which includes a base plate mountable to an article of construction machinery and a first working plate movable relative to the base plate. First and second shafts are mounted to the first working plate. The first shaft is guided by first and second spherical bearings fixedly mounted to the base plate. The second shaft is guided by a third spherical bearing adjustably mounted to the base plate. The third spherical bearing is attached to a third shaft which is disposed normal to the first and second shafts. A cylindrical bearing guides the third shaft as it moves in response to misalignment between the first and second shafts. In a similar manner, fourth and fifth shafts are mounted to the first working plate. The fourth shaft is guided by fourth and fifth spherical bearings fixedly mounted to a second working plate. The fifth shaft is guided by a sixth spherical bearing adjustably mounted to the second working plate.

Abstract: Control consoles are normally utilized to provide ready access to the operator of the controls necessary to perform the various operating functions of the vehicle. Since vehicles, such as construction vehicles, are traversing rough terrain, it is advantageous to stabilize movement of the hand of the operator relative to the controls of the vehicle. In this subject arrangement a control console assembly is provided and has a handrest located thereon. The handrest is adapted to receive the hand of the operator such that the heel of the operator's hand remains in intimate contact with a raised portion of the handrest. A pair of levers are mounted on the control console assembly adjacent the handrest and operatively actuated by the fingertips of the operator's hand. A rotary knob is oriented on the side of the handrest and operative to be rotated by the thumb of the operator's hand.

Abstract: A cartridge pin mounting wherein a cartridge pin is secured in accurately preselected relationship to a frame having a mounting hole opening through an outer surface thereof. An outer surface associated with the pin is urged into flush relationship with the outer surface of the frame by a retainer which, in turn, is locked in the frame opening by a suitable locking ring. The outer surface of the pin may be defined by a ring structure at the outer end of the pin, and in the illustrated embodiment, the pin projects slightly from the ring portion.
