  • 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.

  • Patent number: 11964818
    Abstract: A refuse vehicle includes a chassis, a body assembly coupled to the chassis where the body assembly defines a refuse compartment, and a lift assembly pivotably coupled to the body assembly. The lift assembly includes a first lift arm, a second lift arm, a pin having a first end coupled to the first lift arm and an opposing second end coupled to the second lift arm, a pair of forks pivotably coupled to the first lift arm and the second lift arm, an electric lift actuator coupled to the pin, and an electric fork actuator coupled to the pair of forks. The electric lift actuator is configured to rotate the pin to lift the first lift arm and the second lift arm. The electric fork actuator is configured to pivot the pair of forks relative to the first lift arm and the second lift arm.

  • 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: 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.

  • Publication number: 20100049487
    Abstract: There is provided a method comprising the steps of determining an environmental impact of a product by: identifying one or more processes performed during the life cycle of the product; selecting identifying at least one design parameter relating to a the product and being associated with the identified process or processes; representing each of the identified processes by a process model, the process model identifying interventions by the process on the environment; and quantifying the interventions of each process on the environment using the at least one design parameter; and determining at least one environmental impact of the product from the design parameter or parameters; and generating an output indicating the environmental impact of the product.
