  • Publication number: 20240166434
    Abstract: A refuse vehicle includes a chassis, a body assembly, and an automated reach arm. The body assembly is coupled to the chassis and defines a refuse compartment configured to store refuse material. The automated reach arm includes a refuse container engagement mechanism, at least one electrically driven actuation mechanism, a first slew motor, and a second slew motor. The refuse container engagement mechanism is configured to selectively engage a refuse container. The at least one electrically driven actuation mechanism is configured to selectively actuate the automated reach arm between an extended position, a retracted position, and a refuse-dumping position. The first slew motor is configured to selectively swing the automated reach arm with respect to the body assembly about a first axis. The second slew motor is configured to selectively swing the refuse container engagement mechanism with respect to a second axis that is parallel to the first axis.

  • Publication number: 20240116706
    Abstract: A refuse vehicle includes a chassis, a body assembly, and a tailgate. The body assembly is coupled to the chassis and defines a refuse compartment configured to store refuse material. The tailgate comprises a refuse receiving portion, a thresher assembly, and an electrically driven actuation mechanism. The refuse receiving portion is configured to receive refuse material. The thresher assembly includes a compaction thresher including a plurality of tines and a plurality of tine springs configured to bias the plurality of tines in a direction of compaction. The plurality of tine springs are each disposed around a corresponding tine of the plurality of tines. The electrically driven actuation mechanism is configured to selectively actuate the thresher assembly.

  • Patent number: 11919460
    Abstract: A vehicle includes a rolling chassis structure and a working component coupled to the rolling chassis structure. The rolling chassis structure includes a chassis, a non-working component, and a control interface. The non-working component is coupled to the chassis and is configured to facilitate transit operations for the rolling chassis structure. The control interface is disposed in a cab area of the chassis. The control interface is communicably coupled to the non-working component and is configured to control operation of the non-working component. The working component is configured to move relative to the chassis and is communicably coupled to the control interface. The control interface is configured to control movement of the working component.

  • Patent number: 11919708
    Abstract: A refuse vehicle comprises a chassis, a body assembly, a battery system, and a side-loading lift assembly. The body assembly is coupled to the chassis and defines a refuse compartment configured to store refuse material. The battery system is configured to be charged via at least one of an on-board electrical energy generator, an external power source, or a power regenerative braking system. The side-loading lift assembly comprises a refuse container engagement mechanism and at least one electrically-driven actuation mechanism. The refuse container engagement mechanism is configured to selectively engage a refuse container. The at least one electrically-driven actuation mechanism is powered by the battery system and is configured to selectively actuate the side-loading lift assembly between an extended position, a retracted position, and a refuse-dumping position.
