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.
Combining intelligent controls with some of the highest-quality hardware available on the market, Columbus McKinnon presents its first smart actuator: the Duff-Norton® SPA Linear Actuator with Intelli-Motion™️ Technology. As the latest product to join our family of automation-focused solutions, this intelligent actuator offers ease of installation, quick configuration, and simple operation to ensure your system can get up and running quickly.
Smart linear actuators combine intelligent solutions with robust machinery to enable easy installation, configuration, and operation so systems can get up and running quickly and perform reliably. By incorporating these intelligent capabilities, such as those available from a variable frequency drive (VFD) or electronic programmable limit switches (EPLS), smart actuators become easier to set up, operate, adjust, troubleshoot, and monitor.
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.
The Essentials Platform Screw Jack is a robust, cost effective solution developed with safety in mind. The limited screw lengths and options make this screwe jack easy to specify and configure. Learn more and request a quote for your application!
When operating a linear actuator in a challenging environment, such as a mining operation, there are several things you’ll need to consider.
