  • Publication number: 20120193157
    Abstract: A cab suspension device for an agricultural tractor comprising a pair of concentrically aligned tubes co-axially arranged around a conventional cab suspension spring apparatus. One of the pair of tubes is connected to the tractor frame while the second is attached to the cab frame. The lengths of the tubes are shorter than the static length of the spring apparatus to allow limited telescoping movement of the tubes during dynamic compression of the spring apparatus without causing contact between the tube ends and the opposing tractor and cab frames. The dynamic extension during telescoping movement of the spring apparatus is controlled by a spring retainer. An annular space between the tubes allows for limited lateral displacement of the spring apparatus without causing contact between the tubes. The limits are configured to permit normal operational movement of the spring apparatus without contact of the tubes.

  • Patent number: 8225903
    Abstract: A suspension for a cab base on the frame of a swather tractor includes four dampened springs at the four corners with three links each pivoted on one end of the frame and the other end on the base. The links include two parallel links in the fore and aft direction parallel to the mechanical speed control link arm and one side to side link which constrain movement of the base against fore and aft movement and side to side movement parallel to the mechanical steering control link arm. This arrangement restricts movement of the base while allowing roll and pitch movements of the cab structure with the links arranged such that steering and ground speed are substantially unaffected when the cab moves on the suspension.

  • Patent number: 8025013
    Abstract: A rail vehicle having a single frame assembly and a movable platform coupled thereto is provided. The rail vehicle indexes, i.e. advances intermittently, along railroad rails. The movable platform advances in a single direction at a generally steady speed as the rail vehicle indexes along a railroad. The platform is the floor of, or a base for, a cabin preferably having a seat, roof support, and controls for the operator. The platform rides longitudinally with the machine on rollers or slides, thus separating the operator and controls from the rest of the machine. Thus, while the rail vehicle moves in an abrupt stop-and-go manner, the platform and the operator move generally consistently in a single direction.

  • Patent number: 7975793
    Abstract: A foot pod for use with the operator cab of a construction vehicle is designed to pivot separately from the operator cab. The operator cab may be pivoted toward the rear of the construction vehicle and the foot pod may be pivoted toward the front of the construction vehicle. Pivoting the foot pod toward the front of the vehicle permits ground access to the foot pod and any controls carried thereby. Separately pivoting the foot pod forward is particularly advantageous for cleaning the foot pod or servicing any controls carried by the foot pod. Isolation mounts may be used to dampen vibrations from the chassis to the foot pod and the operator cab.
