It is intended to easily perform a work concerning lifting of the crawler. A crawler frame has a crawler frame outer surface that is opposite to a surface via which the crawler frame is attached to a traveling body main part in the left-right direction. A bracket includes an attaching part, a circuitous part, and a crawler lifting section. The attaching part is attached to the crawler frame outer surface. The circuitous part is partially arranged below and above a crawler belt on an outer side thereof in the left-right direction, and extends around the crawler belt. The crawler lifting section is connected to the circuitous part and arranged above the crawler belt for receiving the crawler lifting tool.

A caterpillar changing apparatus includes a floor frame; a moving fame movable with respect to the floor frame; and a supporting unit including at least one body, the supporting unit provided on the moving frame and configured to support a caterpillar to maintain a shape of the caterpillar that the caterpillar has when installed on a vehicle.

The present disclosure provides a system and multicomponent apparatus for removing and installing a continuous track on a power machine or work vehicle. The system includes a support and biasing apparatus, an arcuate positioning component, a decoupling component, and interconnecting elements. The interacting apparatus and components include contact surfaces that bear against the continuous track surfaces to transfer and/or apply a series of forces, each force in the series comprising at least one of an upward, forward, or lateral force, or combinations thereof, to remove the track from or urge and install a replacement track into proper alignment and captive engagement with front idler and sprocket wheels of a continuous track vehicle wheel assembly. Removal and installation of continuous tracks is hereby achieved in a fraction of the time and with substantially less manpower than previously proposed solutions and methods.

A pivot assembly for connecting a ground-contacting wheel assembly to a frame member of a track system assembly has a base defining a first interlocking member, a resilient body structured for being received at least partially within the base and having a second interlocking member connectable to the first interlocking member, and an axle assembly configured for rotatably connecting the ground-contacting wheel assembly to the frame member, the axle assembly including a third interlocking member connectable to the second interlocking member. The resilient body is at least partially wrappable around the peripheral surface of the axle assembly. Upon deformation of the resilient body, the axle assembly is pivotally movable relative to the frame member of the track system assembly about at least one of a longitudinal axis and a vertical axis.

A heavy-duty vehicle may include a crawler track on which a rest of the vehicle can roll so as to move. A sensor may be configured to detect a physical quantity of the crawler track, of the heavy-duty vehicle, or of the environment contained by or surrounding the crawler track or the heavy-duty vehicle. A power supply unit may be configured to supply the sensor with electric power. The power supply unit comprises a rectenna configured to receive electromagnetic power from an external electromagnetic source and to supply the sensor with at least part of the electromagnetic power.
