Abstract: A device for lifting and loading materials employs a pick-up arm for engaging material at ground level and an associated lift arm assembly. The pick-up arm can be swung relative to the lift arm about an axis that is generally perpendicular to the ground to bring the pick-up arm into a close-in position in front of a cab and into an outreaching position. The pick-up arm is automatically moved into the outreaching position as the lift arm moves toward a ground level load position and is automatically moved into the close-in position as the lift arm moves toward the off-load level above ground to facilitate off-loading operations above ground. The pick-up arm is also automatically maintained in a desired vertical relationship, parallel to the ground, as the lift arm moves between the load level and a predetermined level above ground level. When moved closer toward the off-load position, the pick-up arm is automatically vertically tipped to facilitate off-loading operations.

Abstract: A universal engaging mechanism for handling collection containers of a variety of sizes and shapes. The mechanism includes two arms rotatably mounted to a base and movable between open and closed positions, and a retainer located adjacent the base and between the arms. As the arms close about the container, the arms urge the container in a transverse direction toward the base, until the container abuts the retainer. The arms and the retainer also cooperate to inhibit longitudinal movement of the container and container sway during handling. A method for using the universal engaging mechanism of the present invention to handle containers of a variety of sizes and shapes using the universal engaging mechanism is also described.
