ABSTRACT:
The specification discloses a device for tilting a truck box cover to an angular position thus providing improved access to the cargo area. The box cover is mounted to the side of the truck box by a hinge. The box cover is assisted in lifting to an open position and held open by an actuator which may be a single gas spring or a screw powered by an electric motor. The actuator is positioned near the front of the truck box so it causes minimum obstruction of the cargo space. The device may be used with conventional truck box covers. The box cover can be stabilized in a non-closed position by a steady strut. A restraint prevents over-opening of the box cover. A strong frame prevents excessive deflections of the box cover and enables the use of one actuator.
