Abstract:
A top hinged gate assembly for selectively opening and closing a discharge opening of a dump body, comprising a gate for closing the discharge opening of the dump body when said gate is in a generally vertical position, at least one hinge arm mounted to said gate, a first pivot structure located above and forward of said gate, said hinge arm being pivotally mounted to said first pivot structure, a gravity release lever pivotally mounted to said first pivot structure, a variable length power actuator mounted to said gate, a second pivot structure displaced from said first pivot structure, said second pivot structure being mounted to said gravity release lever, said actuator being pivotally mounted to said second pivot structure, an increase in the length of said actuator causing said gate to rotate from a closed position to an open position which is generally perpendicular to said closed position to be generally parallel to the body floor, and said gravity release lever permitting said gate to rotate beyond said open position in response to an object contacting said gate.
