  • Publication number: 20250145371
    Abstract: The refuse lift arm system includes a grabber device configured to engage the refuse container and a container lift. The container lift includes a carriage, a rail assembly, and a tipping mechanism. The carriage supports pivotal movement of the grabber device. The rail assembly supports translational movement of the carriage. The tipping mechanism is configured to pivot the grabber device relative to the carriage in response to relative movement between the carriage and the rail assembly. The refuse lift arm system further includes a horizontal positioning system configured to move the rail assembly laterally relative to the refuse collection vehicle.

  • Publication number: 20250136371
    Abstract: A refuse collection vehicle with a wheeled vehicle chassis and a refuse-collecting body coupled to the wheeled vehicle chassis. The refuse-collecting body includes a refuse storage, a track, and a refuse packer. The refuse storage has a width direction and a length direction. The track extends along the length direction of the refuse storage. The refuse packer has a ram, a fixed bracket, and a wear bar. The ram defines a refuse-contacting surface in the width direction of the refuse storage. The fixed bracket is secured to a lateral surface of the ram in the length direction of the refuse storage. The wear bar engages the track and mechanically couples to the fixed bracket by a releasable fastener. The wear bar is supported on the fixed bracket by at least three spaced apart connection components in the length direction.

  • Publication number: 20240124223
    Abstract: A front-loading refuse vehicle includes: a chassis; a cab coupled to a portion of the chassis, a hopper coupled to the chassis of the cab, and an arm assembly configured to move a refuse container from a location on one side of the refuse collection vehicle. The arm assembly includes a refuse container holder and a boom configured to move the refuse container holder relative to the chassis between an extended position and a retracted position. The boom includes a band including a bistable material reversibly configurable between a stowed configuration and a deployed configuration.

  • Publication number: 20230312240
    Abstract: A refuse vehicle body includes a hopper configured to receive refuse and a storage container configured to store compacted refuse. A tailgate is coupled to a rearward facing side of the refuse vehicle body and is movable between closed and opened positions. The refuse vehicle body includes a rear loading assembly configured to (i) engage a refuse container at a rear side of the refuse vehicle body, (ii) lift the refuse container over a top end of the tailgate, and (iii) rotate the refuse container above the hopper such that the refuse container is unloaded into the hopper. The refuse vehicle body further includes a refuse packing assembly configured to transfer refuse from the hopper and compact said refuse in the storage container.

  • Publication number: 20230076113
    Abstract: A rear loading refuse vehicle includes a tailgate coupled to a rearward end of the body. The tailgate includes a modular refuse packing assembly removably mounted therein and configured to compact refuse received in a hopper into a storage chamber located in the body. The modular refuse packing assembly may include a frame supporting an actuator and a blade. The frame is removably coupled to the tailgate. The actuator is configured to move the blade between extended and retracted positions and thereby compact the refuse received in the hopper.

  • Publication number: 20230008771
    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.

  • Publication number: 20220363474
    Abstract: A refuse vehicle body includes a tailgate coupled to the body. The tailgate is movable between closed and open positions. An ejector is deployed in the body and configured to translate between forward and rearward positions. An actuator is configured to translate the ejector between the forward and rearward positions and is further configured to provide an actuation force that moves the tailgate from the closed position towards the open position and thereby at least partially opens the tailgate.
