A straddle carrier crane is a mobile lifting equipment specifically designed for moving and stacking containers. Users utilize it in port terminals, container yards, manufacturing industries, and large logistics centers. The straddle carrier crane is designed with a “gantry” structure, which allows it to straddle materials directly and lift, transport, and stack goods from the ground to a designated location using a spreader.
The machine is equipped with four to eight large tires, enabling it to maneuver with ease in paved yards, at the dockhead, and within the confined spaces of ship holds. Its effective internal clear width ranges from 3,100 mm to 3,750 mm, which is sufficient to span standard 20-foot or 40-foot containers while leaving ample safety clearance on both sides.
