Ammunition loading vehicle and method
First Claim
1. A vehicle operable in multiple steering modes comprisinga front wheel steering system and a rear wheel steering system,a switch adapted to select the steering mode,a sensor adapted to sense the front wheel steering system reaching a straight position, anda computer control responsive to setting of the switch to a mode and the sensor sensing straight position of the front steering system adapted to change the steering mode of the vehicle,wherein with the switch set to a work mode for the vehicle and the sensor sensing the front wheel steering system being in a straight position, the computer control automatically adjusts the front and rear steering systems to combine together into one unit for relatively accurate steering and relatively small turning radius for the vehicle.

Abstract
A motorized hydraulically-operated and driven aircraft loading vehicle is particularly suited for the loading of bombs, which are raised by a pair of hydraulically-operated arms. Vehicle has two selectable operation modes. A first, working mode provides four-wheel hydraulic steering and enables vehicle to be driven at a small turning radius, and at a speed of up to 10 km/h. A second, traveling mode automatically locks the rear wheel steering system allowing vehicle to be driven at a speed of up to 20 km/h, all being computer controlled.
Safety devices include an emergency stop switch and a no-driver no-actuation switch, and devices preventing accidents if hydraulic power is lost.

17. A vehicle operable in multiple steering modes comprising,
a front wheel steering system and a rear wheel steering system, a switch adapted to select the steering mode, a sensor adapted to sense the front wheel steering system reaching a straight position, and a computer control responsive to setting of the switch to a mode and the sensor sensing straight position of the front steering system adapted to change the steering mode of the vehicle, wherein the computer control is adapted to increase the fluid output capability from the adjustable pump to increase vehicle speed when the steering mode is two wheel steering and to reduce the fluid output capability from the adjustable pump to decrease vehicle speed when the steering mode is four wheel steering mode.
