Abstract
A safety device for a banking vehicle includes a pair of cylinders which extend to hold the superstructure in an upright position. The cylinders are hydraulically connected to an accumulator which provides a pressurized fluid reservoir. A valve controls flow from the accumulator to the cylinders. Upon detection of a failure in one of the vehicle systems the valve moves to a position in which fluid flows from the accumulator to extend the cylinders. A pilot operated check valve is positioned between the accumulator and the cylinders to hold the cylinders in the extended position until the failure is rectified.
