Abstract
An hydraulic tilt system and method for its use with a cab pivotally mounted on a motor vehicle frame. An hydraulic piston-cylinder assembly pivotally connects between the cab and the frame. A remote control station has an hydraulic pump, a reservoir, and a control for operating the pump to tilt the cab. Hydraulic lines connect the control station with the piston-cylinder assembly. Check valves in the hydraulic lines stop the tilting motion of the cab in case of loss of hydraulic pressure. A controlled return free-fall valve is also disposed in the hydraulic lines to selectively restrict the flow of hydraulic fluid.
