US 12,122,598 B2 · Refuse vehicle with electric reach apparatus

Abstract

A refuse vehicle includes a chassis, tractive elements, a lift apparatus, and a reach assembly. The tractive elements couple with the chassis and support the refuse vehicle. The lift apparatus includes a track and a grabber assembly. The track includes a straight portion and a curved portion. The grabber assembly releasably grasps a refuse container and ascends or descends the track to lift and empty refuse into a body of the refuse vehicle. The reach assembly includes an outer member, a first extendable member, and a second extendable member. The first extendable member is received within an inner volume of the outer member and translates relative to the outer member. The second extendable member is received within an inner volume of the first extendable member and translates relative to the first extendable member. The lift apparatus is fixedly coupled at an outer end of the second extendable member.
