  • Publication number: 20200346858
    Abstract: A refuse vehicle includes a chassis, multiple tractive elements, a reach assembly, and a fully-electric lift assembly. The multiple tractive elements are coupled with the chassis and support the refuse vehicle. The reach assembly is coupled with the refuse vehicle. The fully-electric lift assembly is coupled with the reach assembly and includes a track, a carrier assembly, an electric motor, and a drive member. The track includes a straight portion and a curved portion. The track includes multiple channels that extend along an entire length of a path of the track and multiple engagement members. The carrier assembly is configured to move along the path of the track. The electric motor is fixedly coupled with the carrier assembly and drives a driveshaft. The drive member is rotatably fixedly coupled with the driveshaft and engages the multiple engagement members to drive the carrier assembly to ascend or descend along the track.

  • Publication number: 20200346861
    Abstract: A refuse vehicle comprises a chassis, a body assembly, a power source, a tailgate, and a refuse interaction mechanism. The body assembly is coupled to the chassis and defines a refuse compartment configured to store refuse material. The refuse interaction mechanism comprises a refuse interaction element and an electric motor. The refuse interaction element is configured to selectively apply a force onto the refuse material within the refuse compartment. The refuse interaction element is moveable between a receiving position, in which the refuse compartment is configured to receive refuse material, and a force-exerting position, in which the refuse interaction element is configured to exert the force on the refuse material stored within the refuse compartment. The electric motor is powered by the power source and configured to selectively move the refuse interaction element between the receiving position and the force-exerting position.

  • Publication number: 20200346857
    Abstract: A refuse vehicle includes a chassis, a body assembly coupled to the chassis and defining a refuse compartment, an electric energy system, and a lift assembly. The lift assembly includes a pair of lift arms pivotally coupled to the body assembly, a pair of forks pivotally coupled to the pair of lift arms, a lift arm actuator positioned to facilitate pivoting the pair of lift arms relative to the body assembly, and a fork actuator extending between the pair of lift arms and the pair of forks. The fork actuator is positioned to facilitate pivoting the pair of forks relative to the pair of lift arms. The lift arm actuator and the fork actuator are powered by the electric energy system.
