Abstract: A robotic cargo system provides an ability to move cargo without requiring the use of additional material handling equipment such as forklifts and K-loaders. The robotic cargo system may operate as a vehicle during drive maneuvering, and may operate to lockdown on an aircraft as a pallet during flight. The system may navigate over rough terrain while carrying heavy loads through the use of a track-based propulsion system. The system may provide a cargo loading system, ramp ascent and descent algorithms, and autonomous navigation.

Abstract: A track assembly for traction of an off-road vehicle, such as an all-terrain vehicle (ATV) or a snowmobile, is disclosed. The track assembly comprises a plurality of track-contacting wheels, which comprises: a drive wheel; and a plurality of idler wheels spaced apart in a longitudinal direction of the track assembly. The track assembly also comprises an endless track disposed around the track-contacting wheels. A frame of the track assembly may comprise a hollow frame structure. The hollow frame structure may be dimensioned to impede accumulation of snow, mud, rocks, debris, etc. in the track assembly. The track assembly may comprise interwheel guides between longitudinally adjacent ones of the idler wheels to contact a bottom run of the endless track, and/or fenders adjacent to given ones of the idler wheels. The frame's hollowness, the interwheel guides, and/or the fenders may be realized during molding of a portion of the frame using a blow molding or other fluid-based molding process.

Abstract: A method for automatically controlling vehicle speeds of a track-based work vehicle may include monitoring, with a computing device, a load transmitted through a pivot pin of a track assembly of the work vehicle and determining, with the computing device, a speed limit setting for the work vehicle based on the monitored load, wherein the speed limit setting is associated with maintaining an operating temperature of a track of the track assembly below a predetermined temperature threshold. In addition, the method may include automatically limiting, with the computing device, a vehicle speed of the work vehicle based on the determined speed limit setting.

Abstract: 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).

Abstract: A paving machine for spreading, leveling and finishing concrete having a main frame, center module, bolsters laterally movably, and a crawler track associated with respective aft and forward ends of the bolsters. A bolster swing leg for each crawler track supports an upright jacking column. A worm gear drive permits rotational movements of the crawler track and the jacking column. A hinge bracket is interposed between each swing leg and a surface of the bolsters to enable pivotal movements of the swing leg. A length-adjustable holder engages the pivot pin on the hinge bracket and pivotally engages the swing leg. The holder permits pivotal motions of the swing leg in its length-adjustable configuration and prevents substantially any motion of the swing leg in its fixed-length configuration. A feedback loop cooperates with transducers keeping the crawler tracks position. The paving machine can be reconfigured into a narrowed transport configuration.

Abstract: A self-propelled paving machine includes a plurality of swing legs, each swing leg being supported from a ground surface by an associated crawler track steerably connected to an outer end of its associated swing leg. The machine may be re-oriented from a paving mode to a transport mode by driving the ground engaging units to rotate the frame substantially in place on the ground through a re-orientation angle of the frame relative to the ground, and as the frame is rotating, pivoting one or more of the swing legs from a paving position relative to the frame, to a transport position relative to the frame.
