    Abstract: A hand-drawn cart for transporting one or more containers has raised sides and a rear ramp that may be locked in a vertical transporting position or unlocked and rotated into an unloading position. A recycling bin or other containers may be stored upon the cart, loaded with recyclables, then the cart may be rolled to a curbside collection location with the ramp locked. The ramp is unlocked and lowered at the collection location, the front end of the cart is lifted to slide a container down the ramp, the cart is drawn forward to withdraw the ramp from beneath the container, and the ramp is rotated back up to a locked position.
