AUTOMATED REFUSE VEHICLE

摘要

An automated device for lifting and loading materials employs a pick-up arm (32) for engaging material at ground level and an associated, inverted Ushaped lift arm (40). The pick-up arm (32) can be swung relative to the lift arm about a vertical axis (148) to bring the pick-up arm (32) into a close-in position in front of a cab and into an outreaching position. The pick-up arm (32) is automatically moved into the outreaching position as the lift arm (40) moves toward a ground-level load position and is automatically moved into the close-in position as the lift arm (40) moves toward the off-load level above ground to facilitate off-loading operations above ground. When moved closer toward the off-load position, the pick-up arm (32) is automatically vertically tipped to facilitate off-loading operations. During off-loading operations, the vertical height of the container (30) and lift arm assembly (40) is minimized through the use of a dump link and associated four-bar linkage.
