Refuse vehicle with electric lift
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.

A refuse vehicle includes a chassis, an energy storage device, a body, and an electric power take-off system. The energy storage device (e.g., a battery) is supported by the chassis and is configured to provide electrical power to a prime mover. Activation of the prime mover selectively drives the refuse vehicle. The body is configured for storing refuse, and is supported by the chassis. The electric power take-off system is positioned on the body and includes an inverter, an electric motor, and a hydraulic pump that is drive by the electric motor. The inverter receives electrical power from the energy storage device and supplies electrical power to the electric motor. The electric motor drives the hydraulic pump to convert the electrical power into hydraulic power.
