Abstract
A straddle carrier having a generally U-shaped frame with a spreader supported in the opening of the U-shaped frame is disclosed herein. The spreader is raised and lowered by two fluid rams which respectively cooperate with opposite ends thereof and hydraulic fluid is supplied to the fluid rams by a hydraulic circuit that includes an electrical circuit which automatically prevents the spreader from tilting beyond a maximum angular attitude with respect to a horizontal reference plane.
