Abstract
A refuse collection apparatus is adapted to grab and lift a refuse container, dump the contents thereof into a collection bin, and return the container to its original location. The apparatus includes a container grab assembly which includes a pair of opposed grabbing arms that are aligned in spaced relationship and operable by a fluid-operated actuating system to grab and release a container. The apparatus also includes an articulated, moveable arm assembly that is operable by a fluid-operated actuating system through an operating cycle that includes retracted, extended, lifting and dumping positions. The arm assembly of the apparatus is designed to balance the mass of the apparatus during the operating cycle while balancing actuation of the actuators employed therein to allow for effective cushioning at the ends of the stroke of each actuator.
