  • Patent number: 11173825
    Abstract: A refuse vehicle includes a chassis, a plurality of tractive elements coupled to the chassis, and a lift assembly including a carriage, a grabber arm selectively repositionable between an engaged position and a disengaged position, a track configured to be coupled to a chassis of the refuse vehicle, and a roller assembly slidably coupling the carriage to the track. In the engaged position, the grabber arm is configured to couple a refuse container to the carriage. The track defines a track groove extending at least partway along a length of the track. The roller assembly includes a base coupled to the carriage, a shaft coupled to the base and extending outward from the base, a roller extending at least partially into the track groove, the roller defining first a central aperture that receives the shaft, and a bushing that rotatably couples the roller to the shaft.

  • Patent number: 9408379
    Abstract: A break-away apparatus for a boom arm has a main boom portion and a boom tip. The apparatus is positioned at a joint between the main boom portion and the boom tip. The apparatus allows the boom tip to assume a neutral position and to pivot to a forward position and to a rearward position with respect to the main boom portion. The apparatus includes a first plate disposed at the joint, a second plate disposed at the joint, a hinge assembly positioned between the first plate and the second plate, a cam element attached to the first plate, the cam element having an arcuate surface, and a roller attached to the second plate and positioned to roll against the arcuate surface.

  • Patent number: 9265243
    Abstract: A break-away apparatus for a boom arm is positioned at a joint between the main boom portion and the boom tip. The apparatus allows the boom tip to assume a neutral position and to pivot forward and rearward. The apparatus includes a first plate disposed at the joint, a second plate disposed at the joint, and a hinge assembly positioned between the first plate and the second plate. The hinge assembly includes a hinge pin having a longitudinal axis. The first and second plates are in a first position with respect to each other when the boom tip assumes the neutral position. The first and second plates are movable with respect to each other about the longitudinal axis. A torsion spring is configured to return the first and second plates to the first position after the first and second plates move from the first position.

  • Publication number: 20130248619
    Abstract: A tilting boom applicator broadly includes a laterally-extending applicator boom a lift, and a tilt frame. The lift includes upper and lower lift arms that support the applicator boom and are operable to vertically shift the applicator boom. The tilt frame interconnects the applicator boom and lift and includes a fixed section mounted to upper lift arms and a swinging section mounted to the applicator boom. The frame sections are attached to each other at a frame pivot joint that defines a longitudinal tilt axis, with the frame pivot joint permitting tilting movement of the applicator boom relative to the lift about the longitudinal tilt axis. Lower lift arms are directly attached to the swinging section to limit movement of the applicator boom relative to the lift about a lateral pitch axis while permitting the tilting movement.
