An all-terrain telehandler includes a pair of front tracks. Each front track may be coupled to a front bracket by an arm that telescopes relative to the front bracket. A superstructure may be coupled to the front bracket where the superstructure supports a first telescoping boom. A pair of rear tracks may be coupled to a rear body. The rear body may be coupled to the front superstructure. A maximum extension position for the first telescoping boom and a length generally corresponding to a length of the superstructure may define a ratio of approximately 4.00:1.00, whereby the all-terrain telehandler is substantially stable when moving loads supported by the first telescoping boom. A second telescoping boom may support a cab. With the second boom, the cab may be lowered beneath a top section of one of the front tracks for facilitating an operator loading sequence.

A sprocket may be configured for driving engagement by a corresponding one of the front axle and the rear axle, with the sprocket drivingly engaging the track.

The invention relates to a tracked vehicle (11) comprising a vehicle body (30), at least one track assembly (21) and a suspension device (S). Said track assembly (21) is arranged to be supported by said vehicle body (30) by means of said suspension device (S), said track assembly comprising a track support beam (22) for supporting a plurality of road wheels (23, 23a), an endless track (25) being disposed around said road wheels. Said suspension device (S) comprises a bogie arrangement (50) rotatably attached to a fastening point (P0) of said vehicle body (30) about an axis of rotation (Z0) transversal to the longitudinal extension of said track assembly (21) and attached to said track support beam (22) in connection to at least two fastening points (P1, P2) so that the track support beam (22) is allowed to rotate in a rotational plane extending along the longitudinal extension of said track support beam (22) about said axis of rotation.

A giant six-legged polar research vehicle with tracked feet, including a platform, six legs arranged at six ends of the platform and six tracked feet arranged below the six legs. A monitoring device is arranged on a top cover. Six power compartments each having a steering device are arranged at six ends of a chassis in the platform. Each leg includes a main traveling device with an upper end and a lower end respectively connected to the steering device and a tracked foot, an auxiliary traveling device with an upper end and a lower end respectively connected to the chassis and the main traveling device, and a connecting device arranged on the main traveling device. The tracked foot includes a main flipping mechanism, an auxiliary flipping mechanism, a tracked foot slewing device, a crawler, a sliding plate and a suspension.

Vehicles, control systems for vehicles, and methods of operating vehicles are disclosed herein. A vehicle includes a frame structure, a front section, a rear articulation section, and a control system. The front section is coupled to the frame structure and to a front plurality of wheels supported for movement on a front axle. The rear articulation section is coupled to the frame structure and to a rear plurality of wheels supported for movement on a rear axle. The rear articulation section is pivotally coupled to the front section via an articulation joint and arranged opposite the front section along a vehicle axis. The control system is coupled to the frame structure and includes a mode selector configured to provide input indicative of a mode selected by an operator in use of the vehicle and a controller communicatively coupled to the mode selector.

A track system for a vehicle has an attachment assembly mountable to a chassis of a vehicle and defining an attachment-assembly-pivotable connector pivot axis; a track assembly including a support frame disposed laterally outward from the attachment assembly, the support frame including a leading frame assembly and a trailing frame assembly, each frame assembly including a frame member connectable to the attachment assembly pivotable connector and a frame-suspension pivotable connector; at least one wheel-load-bearing connector, and at least one idler wheel being at least indirectly connected to the frame member via the at least one wheel-load-bearing connector. The track system further has a sprocket wheel, an endless track, and a suspension assembly having a forward suspension pivotable connector, a rearward suspension pivotable connector, and a suspension member operatively connected to the forward suspension pivotable connector and to the rearward suspension pivotable connector.

A track system for traction of a vehicle (e.g., a compact track loader or other construction vehicle) which may be designed to improve ride quality (e.g., reduce vibrations) for an operator and/or enhance other aspects of its performance or that of the vehicle. For example, a track of the track system may be frictionally driven and without transversal rigid parts (e.g., metallic cores). Also, power generation and transmission functions may be implemented by the track system. For instance, a motor and a transmission may be at least mostly contained within the track system.

A bogie axle assembly for a vehicle, in particular for an off-highway vehicle such as a forestry machine, the bogie axle assembly comprising: a rigid link arm; a first joint disposed on the link arm for pivotally coupling the link arm to a vehicle frame; a second joint disposed on the link arm, at a distance from the first joint; a bogie pivotally coupled to the link arm via the second joint; and a ground engaging structure comprising one or more wheels rotatably mounted on the bogie. The present disclosure further relates to a vehicle comprising said bogie axle assembly.

Vehicles, systems and methods for providing articulating two section vehicles with tracks, and a front body attached superstructure with telescopic forklift, for use on all terrain condition applications. The vehicle can include front and rear track assemblies that can tilt up and down while traveling over different ground surfaces. Each of the track assemblies can have rotatable articulating/oscillating track wheels which can traverse different contoured surfaces. The right and left tracks on both the front and rear track assemblies can separately extend outward and inward from underneath the vehicles to add stability to the vehicles. The cab can be raised and lowered to add greater visibility for the operator. Hydraulics can be used for raising and lowering the extendable boom and operator cab, as well as controlling the body articulating hinge, the articulating tracks and the tilting controls for the front track assembly.
