A wheeled cabinet includes a container including compartments, a rear handle, drawers, and a storage between the drawers and a base; a pneumatic assembly including an inlet, connectors, a pneumatic cylinder on the base, a piston rod configured to move alternately upward and downward relative to the cylinder, and a controller for activating the cylinder; a lifting assembly including two opposite rails upwardly disposed on two sides of the base respectively, and an inverted U-shaped frame member slidably disposed on the rails and having an underside of a top secured to the piston rod; and a tire support assembly including a support secured to the frame member, two slides on two sides of the support respectively, a sliding tray secured to the slides, a slot on an inner surface of the tray, a moveable tab in the slot, and two rollers on two sides of the tray respectively.

A single-point clamp of four-wheel aligner for vehicles connected to a fixing hub nut on the wheel comprises a sleeve, a single-point variable hexagonal grip, a fastening nut, a connecting board, and a target board with magnets. The single-point variable hexagonal grip and the fastening nut are respectively disposed at two ends of the sleeve. The single-point variable hexagonal grip is firmly lodged in the fixing hub nut. Two ends of the connecting board are respectively connected to the sleeve and the target board. A using method includes: (1) loosening the fastening nut of the single-point clamp; (2) inserting the single-point variable hexagonal grip into the fixing hub nut of the wheel; and (3) rotationally fastening the fastening nut for clamping the fixing hub nut firmly.

Vehicle dimension data describing dimensions of a vehicle are obtained, a robotic apparatus is moved to a position about the vehicle, a reference point of the vehicle is determined, and the robotic apparatus is caused to move to positions about the vehicle based on the reference point. The reference point is a center point of a selected wheel of the vehicle. A coordinate system of the robotic apparatus is aligned to the reference point of the selected wheel of the vehicle. Based on the aligned coordinate system of the robotic apparatus, operations are performed by the robotic apparatus to remove lug nuts from a wheel hub of the vehicle.

A device for lifting a wheel and rolling the wheel on a surface includes an elongated rigid plate having a top side, a bottom side, a peripheral edge, a pedal portion at a rear end of the rigid plate, and a wheel portion at a forward end of the rigid plate. A ground roller is fixed with the bottom side of the rigid plate and at least two wheel rollers are fixed with a top side of the wheel portion. In use, with the wheel resting on the wheel rollers, the pedal portion may be pressed downwardly to pivot the rigid plate about the roller to lift the wheel. The lifting device is then rolled on the surface to place the wheel at a desired position, and rotated until obtaining a desired rotational orientation.

A nut pickup and fastening device for automatic tire mounting includes a nut setting unit that arranges a plurality of nuts to align with the bolt arrangement of the wheel disk of a vehicle body, and a pickup fastener coupled to the tip of a robot arm. The pickup fastener may include a tool frame unit, a plurality of nut runners provided on the tool frame unit corresponding to the set nuts and configured to provide torque for nut fastening, and a plurality of holding sockets coupled to the tip of each nut runner, configured to pick up and hold the nuts from the nut setting unit.

A load balancer includes an articulating assembly connected with a support mechanism. The articulating assembly is connected to a support assembly where the support assembly is able to secure a load thereto. The articulating assembly articulates the support assembly and thereby the load between a first position and a second position. The articulating assembly includes at least one linkage assembly interposed between the attachment member and the support assembly. The at least one linkage assembly includes an arm and an actuator where the actuator is selectively pivotable relative to the arm. The load balance and the load together have a center of gravity. The center of gravity remains substantially aligned with an attachment to the support mechanism during the articulation of the support assembly between the first position and the second position.
