This Autoloc Spreader was designed for a Homeland Security application, which required the need to lift "mini containers" that contained sand. Although the "box" was small at only about 12' long, the weight was not, weighing in at 75,000 lbs. and they needed to be lifted and stacked upon one another. This spreader incorporates all of the rugged, proven components used on our Autoloc spreaders that lift standard containers. Incorporating standard ISO 1161 Corner Fittings into your "box" design will open up many opportunities to take advantage of lifting and tie down devices.
