Abstract: An articulating work vehicle with a radially-pivoting lift arm, attached to a radially-pivoting base. The vehicle has a wheeled back section, on which an operator may stand, and a front, tool-carrying section, connected to the back section by an articulation joint. The front section has a system of actuators. These actuators cause a base tower to pivot relative to a frame, and a loader arm to pivot relative to the base tower. A tool, carried by the loader arm, may be self-levelling, and a bell crank allows the loader arm actuator's reaction point to float relative to the base tower.

Abstract: An articulated work machine with individually powered drive members. Each drive member is controlled by a corresponding electric motor, and is capable of rotating at a different speed and in the opposite rotational direction than all other drive members. Each drive member may also remain stationary while all other drive members rotate. The electric motors are commanded by a controller, which may be directed by inputs from by an operator. A lift arm extends from the front end of the vehicle, and a platform station extends from the rear end of the vehicle. The lift arm is connected to a tool, such as a bucket.
