The present disclosure discloses an apparatus that can be retracted for efficient storage and can be used for transporting materials from one location to another. The apparatus includes a retractable assembly coupled to track members that are expanded and retracted using the retractable assembly. The retractable assembly uses a plurality of arms connected to a slide member that have slide attachment members that move along the slide to retract and expand the present invention. The apparatus can be configured to cooperate with a forklift assembly, a storage box member or platforms to transport materials and loads. The apparatus can be two or four wheel drive and can be configured with more wheel members depending on the desired use.

A mobile lift caddy is configured to remove a vehicle from a primary lift while the vehicle is elevated above the workplace floor and then transport the vehicle to another location. The mobile lift caddy is dimensioned to fit between vertical lift posts of the primary lift. A mobility drive arrangement moves the caddy under operator control to and from the workplace location. Caddy lift arms are configured to accept a portion of removable lift pad assemblies at the lift arms of the primary lift, to lift out the lift pad assembly with the vehicle supported on the lift pads.

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.

Disclosed are various embodiments, aspects and features an oscillating track system that includes an oscillating track lock subsystem. The oscillating track system may include a track operable to rotate around a housing structure that is configured to receive an axle. While in operation, i.e. while the track is being rotated around the housing, the oscillating track system may be able to oscillate about the axle and, in doing so, incline or decline to accommodate undulating terrain. Advantageously, when stopped, the degree to which the oscillating track system has oscillated around the axle may be locked in place via an oscillating track lock subsystem comprised within the oscillating track system, thereby providing stability to the heavy equipment that includes the oscillating track system.

A modular robot system which may be configured to accommodate packages of varying sizes is provided. The modular robot may include a base have omni-directional wheels and cameras and sensors, one or more modular containers, and a lid, which may be releasably linked together to form a small, medium or larger units. The base, one or more modular containers, and the lid may be electrically linked to provide information to be used in a number of ways. For example, the electrical link may allow two or more modular robots to communicate with each other, enable external displays of multiple modules to act as one large unit, control the motion of the drawers, e.g., allowing them to open/close, and allow the processor(s) in the lid to communicate with the drive system of the omni-directional wheels. A set of alternating interlocking rails and tracks on corresponding surfaces enable the various layers of the modular robot to interlock with one another. Interlocking of multiple modular containers may be established by sliding one surface over the other. These sections may be used to create modular robots of varying sizes.

A self-propelled slag transporter, The self-propelled slag transporter includes a drive, a chassis, a lifting device with at least one lifting drive and a receiving device for receiving a metallurgical transport container, in particular a slag container, wherein the receiving device is designed to be height-adjustable by the lifting device, and wherein the chassis has at least two crawler tracks.

An automotive lift system includes at least one stationary primary lift and a mobile lift caddy configured to remove a vehicle from a primary lift while the vehicle is elevated above the workplace floor and then transport the vehicle to another location. The lift system employs detachable pivotable lift arms that are removably attached to the lift arms of the primary lift, and which can transfer to the lift caddy. Also, the lift caddy may have clamp lift pads that can be used to remove the vehicle from the primary lift and either also remove the pivot lift arms or not remove the pivot lift arms. This system can also be used on existing primary lifts.

Compact tool carriers having a loader mounted to a low-profile mainframe are disclosed. In some embodiments, the pivot points of the mainframe about which the loader is pivoted are low relative to the mainframe to reduce the mainframe size.

An omniwheel track system comprising a frame comprising at least one supporting plate, an endless drive mechanism mounted to the frame, and a plurality of segment assemblies mounted to the frame and drivable by the endless drive mechanism, the plurality of segment assemblies forming an endless track rotatable about the frame, each segment assembly comprising a housing adapted to receive at least one load wheel, each load wheel mounted to a corresponding segment assembly and rotatable about an axis, each axis forming an angle with a side of the housing. There is also provided an omniwheel track system platform comprising a plurality of the omniwheel track systems described above arranged on a main frame such that the omniwheel track system platform is movable omnidirectionally.

A straddle fork vehicle includes a generally rectangular frame structure with front and rear forklift assemblies positioned between a set of tread belts. The straddle fork vehicle is designed such that the frame may accommodate, or straddle, agricultural harvesting pallets between the set of treads in a passthrough through area beneath the frame as the vehicle progresses down a field row. Engine configuration and improved braking systems facilitate a safer construction and tighter turning radius.
