Abstract
An articulated lift aim assembly for a refuse receptacle generally includes an engaging device for releasably grasping the receptacle, an extendable boom along with an articulated arm mechanism interconnecting the book and the engaging device. A gear arrangement provides for coupling the boom and the arm for raising the arm mechanism with respect to the boom, rotating the arm mechanism with respect to the boom during raising of the arm mechanism and inverting the engaging device and receptacle during raising of the arm mechanism. A gravity operated hook is provided for latching the receptacle when the receptacle is inverted to prevent undesired release from the engaging device.
