  • Patent number: 11697331
    Abstract: A refuse vehicle includes a chassis, a body assembly coupled to the chassis, an electric energy system, and a door system. The body assembly defines a refuse compartment. The body assembly has a cover that at least partially encloses the refuse compartment such that an opening is defined in the body assembly to provide access to the refuse compartment. The door system is coupled to the cover. The door system includes a panel and an electric actuator powered by the electric energy system. The electric actuator is configured to selectively reposition the panel between a first position where the panel extends across the opening and a second position where the panel does not extend across the opening.

  • Patent number: 8215717
    Abstract: A towable dump trailer is provided. The towable dump trailer comprises a first, second and third frame. The first frame comprises one or more sets of wheels. The second frame is attached to the tow vehicle and can be displaced horizontally relative to the first frame by the towing vehicle moving rearward or forward. The third frame provides a support frame for the trailer bed. The dump trailer is operated by immobilizing the first frame and causing the second frame to move horizontally relative to the first frame. This horizontal displacement causes the third frame to pivot as a result of one or more pivoting arms translating the horizontal movement to pivotal movement. The dump trailer can be configured to provide a dumping action by either forward or rearward horizontal displacement of the second frame relative to the first frame.
