A guard assembly is provided for use with a track assembly for a vehicle. The guard assembly includes a guard body having a rigid portion made of a first polymeric material and a flexible portion made of a second polymeric material different from the first polymeric material. The first polymeric material has a greater modulus of elasticity than the second polymeric material. A vehicle including a guard assembly, namely including a guard body is also contemplated.

A work machine may include an electric motor, an idler wheel, a drivable track engaged with the idler wheel, and an actuator that is electrically powered by the electric motor and configured to move the idler wheel to adjust the tension in the drivable track based on the torque output of the electric motor. The work machine also includes a controller configured to automatically control the electrical current input to the electric motor based on one or more monitored control factors associated with the work machine.

A cargo transport system is provided that has an ability to move cargo in an autonomous or semi-autonomous manner, using a compact lift vehicle capable of lifting relatively heavy objects. The system includes a cargo loading system, a sensor suite coupled with a controller, dunnage detection, cross-decking capability, cargo stacking capability, autonomous navigation, tip detection and prevention, or any combinations thereof. The system may include a fork assembly coupled with a mast and movable in a vertical direction relative to the mast. Further, the mast may be coupled with a platform or deck and movable in a horizontal direction relative to the platform, to allow the fork assembly to be lowered below a top plane of the platform when the mast is at a forward location relative to the platform. The controller and sensor suite and may provide for autonomous or semi-autonomous control and movement of the cargo transport system.

A machine for road work can comprise a frame, a plurality of ground engaging units, a plurality of vertically moveable legs, each leg connecting one of the plurality of ground engaging units to the frame, a pair of spatial sensors, such as global navigation satellite system (GNSS) sensors, and a controller configured to, in response to a three-dimensional signal received from each of the spatial sensors, activate at least some of the plurality of vertically moveable legs.

The invention relates to an articulated vehicle comprising a front and a rear vehicle unit, and at least one further vehicle unit connected to said rear vehicle unit, comprising a front vertical steering link arranged substantially centrally of the front vehicle unit, where said front vertical steering link is configured for pivotal attachment to a fixed load-carrying frame connecting said front and rear vehicle units, where said at least one further vehicle unit is configured for attachment to a further fixed load-carrying frame, where said further fixed load-carrying frame is releasably connectable to said fixed load-carrying frame for said connection, such that a train of vehicle units is formed connected to a load-carrying frame unit comprising said fixed load-carrying frame and said further fixed load-carrying frame.

A track work vehicle includes a track system. The track system includes a drive wheel supported by an axle housing that drives a continuous ground-engaging track, a saddle assembly that guides the track about the drive wheel and an undercarriage frame that supports one or more idler wheels that guide the track along a ground surface. The track work vehicle includes a fender assembly that includes at least one fender coupled to the track system to overlap a portion of the track.

In one aspect of the present invention is provided an attachment device (100) for attachment of a trailing arm (54a) to a track support beam (22) intended to be connected, via said trailing arm (54a), to a center beam (30, 32) or other structural element situated between two track assemblies (21) of a tracked vehicle (10). The attachment device (100) is secured to the track support beam (22) and configured to attach the trailing arm (54a) to the track support beam (22) via an axis (X2) running above and substantially centrally along an upper side of the track support beam (22), in the longitudinal direction of the track support beam. In this way, a robust, structurally strong, suspension-admitting attachment device that is easy to manufacture and assemble is achieved. In another aspect of the invention is provided a tracked vehicle (10) comprising such an attachment device (100) and in a further aspect of the invention a method of manufacturing a track support beam (22) comprising such an attachment device (100).
