Abstract: A straddle carrier consisting of an inverted U-shaped frame, having a pair of vertically extending legs that define an elongated container carrying bay with each leg supported by a plurality of wheels is disclosed herein. First and second engines are respectively supported on the legs and each engine drives a plurality of pumps which supply pressurized fluid for driving and steering the vehicle, as well as pumps for supplying fluid to a plurality of other functions. The hydraulic circuit for performing the plurality of other functions as well as the steering function is designed so that all of the functions may be operated from the pumps driven by one of the engines in case of power failure in the other engine.
