  • Patent number: 4989918
    Abstract: A material handling vehicle is disclosed which includes a substantially rectangular material container with an open rear end. The container is pivotably mounted to the vehicle frame so that the front end of the container can be lifted to cause material in the container to be discharged through the open rear end. A tailgate is mounted to the open rear end of the container and can be selectively moved between a closed position where the tailgate overlies and closes the open rear end of the container, a partially raised position to permit metering of a material therethrough, and a fully raised position where the tailgate is free to swing outwardly about a pivotal axis. A pair of hydraulically actuated lifting members selectively move the tailgate between the three positions.
