Industrial screw jacks are used to lift, position (push, pull, tilt, roll, etc.) and support all kinds of loads. Some applications where our screw jacks have been used include plastics machinery, beverage bottling systems, aircraft assembly and paper production.
Duff-Norton’s collection of screw jacks range from mini screw jacks supporting up to 1,000 pounds to acme screw jacks with a capacity up to 350 tons and everything in between. Learn about our machine and ball screw jacks.
Kern Steel was asked for an aircraft maintenance system that could accommodate various aircraft models. This system required a combination of walk ways, stairs and working platforms along with the ability to adjust the height of each platform in order to reach standard maintenance areas from cockpit to tail.
Since 1883, Duff-Norton has earned a reputation for reliable, high-quality products that meet the industrial lifting, positioning and transfer needs of our worldwide customers.
Both our standard and custom-designed products are subjected to the same rigorous testing throughout the design process to assure maximum performance and quality. We have been ISO 9001 registered since 1994, and practice and conduct lean initiatives regularly.
