The industrial truck includes a pair of support wheels or drive wheels located underneath the vehicle body on a driving surface and opposite one another relative to the width direction. The industrial truck includes a pair of scanner units arranged vertically above the support wheels or drive wheels. The pair of scanning units defines a scanning plane with respective scanning regions each scanning unit of the pair of scanning units, and wherein the respective scanning units are symmetrically opposite one another within an outline of the vehicle body in the width direction of the industrial truck.

A lift device includes a base, an arm, a tractive element, and a steering actuator. The arm has a base end coupled to the base and a tractive element end. The arm includes a steering actuator interface positioned along an exterior surface of the arm. The tractive element is coupled to the tractive element end. The steering actuator has a first end coupled to the steering actuator interface and an opposing second end coupled to the tractive element. The arm includes a plate extending from the exterior surface of the arm at an upward angle and past the steering actuator.

A leveling system for a lift device includes a control system. The control system has programmed instructions to acquire operation data regarding operation of the lift device, fluidly couple a first leveling actuator and a second leveling actuator based on the operation data, acquire an update regarding the operation data, fluidly decouple the first leveling actuator and the second leveling actuator based on the update regarding the operation data, and selectively control the first leveling actuator and the second leveling actuator to (i) selectively reposition a first tractive element and a second tractive element relative to each other about a longitudinal axis defined by the lift device and (ii) selectively reposition the first tractive element and the second tractive element about a first lateral axis defined by the lift device.

Systems and methods provide a torsion bar assembly coupled to one or more casters of a material handling vehicle (MHV). The torsion bar assembly is configured to maintain contact between a travel surface of the MHV (e.g., ground) and a drive wheel of the material handling vehicle throughout the service life of the drive wheel.

An autonomous transport robot for transporting a payload is provided and includes a frame with an integral payload support, a transfer arm connected to the frame for autonomous transfer of payload to and from the frame, and a drive section with at least a pair of traction drive wheels astride the drive section, the drive section being connected to the frame. The at least the pair of traction drive wheels have a fully independent suspension coupling each traction drive wheel of the at least the pair of traction drive wheels to the frame, with at least one intervening pivot link between at least one traction drive wheel and the frame configured to maintain a substantially steady state traction contact patch between the at least one traction drive wheel and a rolling surface over rolling surface transients throughout traverse of the at least one traction drive wheel over the rolling surface.

An industrial truck includes a vehicle frame and a drive unit. The drive unit includes a drive wheel movably mounted to the vehicle frame and a spring unit. The spring unit includes a hydraulic cylinder positioned between the vehicle frame and the drive unit and a switchable valve configured to define a blocked state. The spring unit is configured to pretension the drive wheel against a ground surface. When the switchable valve is in the blocked state, a one-sided movement of the hydraulic cylinder is blocked.

An autonomous guided vehicle comprising a platform adapted to carry a load thereon in a working position; a plurality of suspension devices connected to the platform, each suspension device having a sensor and an actuator; and a plurality of wheels associated with the suspension devices; wherein a first wheel is associated with a first suspension device such that the sensor of the first suspension device is adapted to provide a signal when a relative position of the first wheel and the platform is altered.

An exemplary embodiment may provide a robotic powered cargo handling system. An embodiment may implement a pallet-lift mechanism to lift cargo or pallets. Powered rollers may be embedded into the forks of a pallet-lift mechanism and on top of the vehicle body. An exemplary embodiment may be fully autonomous. A user or software may direct the vehicle to a pallet or piece of cargo and set a destination for the cargo. Sensors, cameras, GPS, and computer vision may be implemented to navigate and avoid obstacles. An exemplary embodiment may include independent 4-wheel steering, 4 corner height adjustment, in-hub electric motors, and pneumatic or solid tires.

A handling robot used in a field of warehouse logistics comprises a mobile chassis, and a storage shelf. The storage shelf is mounted to the mobile chassis and comprises a plurality of layered plate components distributed at different heights. The handling robot further comprises a handling device configured to transport a material to a layered plate of the plurality of layered plate components, and a lift component configured to drive the handling device to lift relative to the storage shelf.

A support system for a vehicle includes a base and at least a first and a second support arm. Each of the first and the second support arms include a base end pivotally coupled to the base through a respective hinge assembly. Each of the first and the second support arms further include a distal end opposite the base end. The support system also includes a respective wheel assembly coupled to each distal end. Each wheel assembly includes an independently powered and steerable wheel configured to engage a travel surface, a propelling motor configured to drive a respective first support arm between a stowed condition and a deployed condition unaided while the vehicle remains stationary, and a steer actuator configured to change an angle of the wheel with respect to a respective support arm.
