    Abstract: Disclosed embodiments include power machines, track frame assemblies, and apparatus for mounting a track frame assembly to a frame of a power machine. In various disclosed embodiments, mounting structures mount a track frame to the machine frame. In some exemplary embodiments, each mounting structure includes two torsional joints and at least three non-torsional joints between the machine frame and the corresponding track frame. The two torsional joints can be provided by torsion shafts and the corresponding attachments to front and rear arms. In exemplary embodiments, the at least three non-torsional joints are substantially free to rotate and can include a joint between a front axle and the track frame, a joint between a rear axle and a link, and a joint between a link pin and the track frame. In some exemplary embodiments, the front or rear arms are oriented relative to corresponding torsion shafts to improve performance.

    Abstract: A tracked vehicle, such as tracked carrier to carry and enable use of work equipment (e,g., a crane, an aerial work platform, a drill rig, etc.) on various terrains, is provided. The tracked vehicle may comprise a frame comprising an equipment mounting area for mounting work equipment above the frame. The frame may comprise a pair of side rails that have a spacing in a widthwise direction of the tracked vehicle which corresponds to a standard truck frame side rail spacing (e.g., 34 inches). An operator cabin comprises a seating area which may comprise a single seat for an operator or a first seat for the operator and a second seat for a second person next to the operator. At least part of a power plant of the tracked vehicle may be mounted above the frame and behind the operator cabin. The tracked vehicle comprises a plurality of track assemblies for traction of the tracked vehicle.

    Abstract: The invention relates to an arrangement for controlling deflection motions of a crawler track driven undercarriage, wherein an undercarriage (2), being meant for a working machine (1) applicable especially for off-road use, comprises on sides thereof stiff crawler track bodies (3) in longitudinal direction (s) of the undercarriage, wherein ends of the crawler track bodies are provided with idle wheels (4) for crawler track use (T). The crawler track bodies (3) are coupled with a center frame (R) of the undercarriage turnably in a vertical plane along the longitudinal direction (s) of the undercarriage by rotating joints (N) between the center frame and the crawler track bodies, wherein at joint points connecting the center frame (R) of the undercarriage and the crawler track bodies (3) is arranged a coupling arrangement (5) for adjusting strain. The arrangement in the undercarriage comprises a pressure medium operated, advantageously hydraulic, adjustment arrangement, whereby a movement in direction of height (h) of the crawler track body on the one side causes a movement of a corresponding magnitude in opposite direction of the crawler track body on the opposite side by using one or more hydraulic cylinders connecting the crawler track bodies (3) and the center frame (R) at least in a power transmitting manner. The hydraulic cylinders belonging to the arrangement that control rolling motion of the crawler track bodies (3) are coupled on opposite sides of the undercarriage by first ends thereof with the first coupling parts of the coupling arrangement (5) and by second ends thereof with second coupling parts of the coupling arrangement (5).
