Abstract
A wheeled lifting device particularly well suited for lifting a stack of nested waste containers. The device includes a lift arm, a handle, and a pair of wheels. The wheels move in an under-center action under the lift arm to lift one side of a stack of containers. When the stack is so lifted it is supported for rolling movement on the wheels of the device and on the wheels of the lower-most container.
