Frequently asked questions

Why are Duff-Norton screw jacks commonly used in industrial lifting systems?
Screw jacks provide precise load positioning, high load capacities, and reliable mechanical lifting without hydraulic systems.
What is the difference between translating and rotating screw jacks?
Translating designs move the lifting screw vertically, while rotating designs rotate the screw while the lifting nut travels.
What factors should be considered when sizing a screw jack system?
Load weight, travel distance, operating speed, duty cycle, and mounting configuration should all be evaluated.
