Abstract
A hydraulic steering synchronization system for use with straddle-type mobile cranes wherein upon actuation of the system and movement of the steering wheels through a normal side-to-side cycle, the movement of the steering wheels provides a signal to effect a balancing flow of hydraulic fluid to the hydraulic cylinders which control the movement of the steering wheels to effect resynchronization of their position, and to correct any misalignment therebetween.
