ABSTRACT:
A dump vehicle, such as for agricultural use, includes a movable support member and a slide structure for supporting and guiding the support member, a container pivotally mounted to the support member, a hydraulic actuator mechanism actuable to lift the container from an original lowered position to a predetermined raised position and to tilt the container at the support member when in the predetermined raised position to a preselected tilted position to permit discharge of the contents of the container. The dump vehicle further includes a hydraulic lock mechanism actuable in response to tilting of the container towards the tilted position to lock the support member in the predetermined raised position to prevent over centering and downward movement of the container from the predetermined raised position during tilting and discharging of the container. The hydraulic lock mechanism is responsive to the container returning to its pretilted position while at the predetermined raised position to unlock the support member and to permit return of the container to its original lowered position.
