A method of operating a construction machine that includes a base, support arms each pivotally coupled to the base, and a plurality of wheel assemblies each coupled to the one of the support arms, the method including, in a transport mode of the construction machine, turning a wheel of each of the wheel assemblies, independently from a wheel of another of the wheel assemblies, to a toe out orientation. The method also includes driving each support arm to a deployed condition of the support arm in an operational mode of the construction machine. Driving each support arm to the deployed condition causes the distal ends of each of the support arms to move away from one another and outwardly from the base. The method also includes locking each support arm in the deployed condition and controlling steering of each wheel in the operational mode of the construction machine.

A mobile transport system includes a vehicle frame, first and second pairs of support wheels, first and second drive wheels, and a swing frame. A drive unit including a drive frame is disposed on the swing frame. The first drive wheel is rotatably supported on a first swing arm, and the second drive wheel is rotatably supported on a second swing arm. The first and second swing arms are coupled to each other by a coupling unit, such that a pivot motion of the first swing arm about a first swing axis in a first pivot direction brings about a pivot motion of the second swing arm about a second swing axis in a second pivot direction oriented opposite to the first pivot direction.

A lift device includes a chassis, a boom pivotally coupled to the chassis, a first leveling assembly pivotally coupled to a first end of the chassis, a second leveling assembly pivotally coupled to an opposing second end of the chassis, and a control system. The first leveling assembly includes a first pair of actuators positioned to facilitate a first pitch adjustment and a first roll adjustment of the first end of the chassis. The second leveling assembly includes a second pair of actuators positioned to facilitate a second pitch adjustment and a second roll adjustment of the opposing second end of the chassis. The control system is configured to (i) actively control the first pair of actuators and the second pair of actuators during a first mode of operation, and (ii) actively control the first pair of actuators and facilitate passive control of the second pair of actuators during a second mode of operation.

A forklift-type automated guided vehicle includes a body and a control circuit unit received in the body, both a first fork arm and a second fork arm parallel to each other and formed on a front end of the body to forklift cargo, each of the first fork arm, the second fork arm and a bottom end of the body including at least one two-wheel differential driving assembly rotatably connected to the first and second fork arms, and the body, respectively, and electrically connected to the control circuit unit. The two-wheel differential driving assembly includes a left driving wheel and a right driving wheel formed opposite to each other which can be independently driven to realize differential rotation. The present disclosure not only can forklift cargo with a small turning radius, but also can realize left-to-right sideways movements and an in-place rotation and a U-turn movement.

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.

A lift machine includes a base having a first end and a second end, a first assembly, and a second assembly. The first end has first and second pivot points defining a first lateral axis. The second end has third and fourth pivot points defining a second lateral axis. The first assembly is pivotably coupled to the first and second pivot points. The first assembly extends away from the base in a first direction such that first and second tractive elements are longitudinally offset from the first lateral axis and spaced from the first end of the base. The second assembly is pivotably coupled to the third and fourth pivot points. The second assembly extends away from the base in a second direction such that third and fourth tractive elements are longitudinally offset from the second lateral axis and spaced from the second end of the base.

The present invention relates to a machine tool (1000) for machining a workpiece (1), comprising: at least one first machine tool structure which can be moved freely on a base surface and has at least one machine tool component, and at least one second machine tool structure having at least one further machine tool component, wherein the at least one freely movable first machine tool structure, together with the at least one second machine tool structure, forms the machine tool (1000) configured for machining the workpiece (1), when the at least one freely movable first machine tool structure is positioned on the at least one second machine tool structure.

A rigid-flexible coupling multi-degree-of-freedom walking position-adjusting leg unit and a hybrid robot platform thereof is provided and includes a vertical rigid-flexible coupling multi-degree-of-freedom walking position-adjusting leg unit and a horizontal rigid-flexible coupling multi-degree-of-freedom walking position-adjusting leg unit, which both include a moving device, a moving drive, a steering frame, a lifting frame, a spring device and an driving differential wheel set, in combination with a frame, a driver set, a battery pack and a control box, forming a multi-degree-of-freedom parallel mechanism platform. The hybrid robot platform including the rigid-flexible coupling multi-degree-of-freedom walking position-adjusting leg unit as provided by the present disclosure has functions of a rigid position adjustment, an elastic suspension and a rigid-flexible coupling position adjustment, and can automatically adapt to a working condition of the uneven ground.

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 handling robot (100), which relates to the field of warehouse logistics, comprises: a mobile chassis (10); a storage shelf (20) mounted to the mobile chassis (10), the storage shelf (20) comprising a plurality of layered plate components (21) distributed at different heights, each layered plate component (21) comprising a layered plate (210) for placing materials; a handling device (40), comprising a handling assembly (42), the handling assembly (42) being configured to handle a material to a layered plate (210) at the same height as the handling assembly (42), or to handle a material out of a layered plate (210) at the same height as the handling assembly (42); and a lift component (30), configured to drive the handling device (40) to lift relative to the storage shelf (20) so that the handling assembly (42) is at the same height as one layered plate (210).
