Abstract
An end gate is provided for a truck box which may be selectively automatically pivotally moved to an open position as the truck box is pivotally moved to its dumping position. A cable interconnecting the end gate and dump box is threaded through a series of pulleys to cause the end gate to pivot outwardly in response to upwardly movement of the dump box.
