Abstract
A refuse collection vehicle having a packer system, a hopper, and a storage compartment. A wall between the storage compartment and the hopper defines an opening that allows refuse to pass from the hopper to the storage compartment. The packer system includes an auger screw and a driver. The driver rotates the auger screw such that refuse is packed into the storage compartment through the opening. A door can be positioned to cover the opening in the wall to inhibit refuse from passing back through the opening. A door actuator system moves the door to selectively open and close the door on the opening. A packing actuator can push an ejector panel across the floor of the storage compartment while the door is closed on the opening in the wall to further compact refuse in the storage compartment or to eject refuse from the vehicle.
