Abstract
A straddle type mobile crane has a pair of hydraulic motor driven front wheels which may be pivoted about a vertical axis for steering. Each motor is supplied by an individual source of pressurized fluid which may be interconnected by a pair of adjustable control valves. A turning crank at each wheel engages a cam coupled to a respective one of the valves so that the hydraulic motors are coupled when the wheels are pivoted through predetermined angles.
