There is a widespread push to replace hydraulic systems with electro-mechanical screw jack systems and for a number of good reasons. The trend has already been under way in Europe for some years and now it is moving to North America. Engineers are being tasked to “design out” hydraulic systems and “design in” screw jack systems for their pushing, pulling, lifting and holding application needs.

Screw Jack Advantages over Hydraulic Systems

The main reasons for moving away from hydraulic systems is to be environmentally friendly and for safety. This is accomplished by eliminating hydraulic fluid spills, costly clean-up, dangerous working conditions, contamination to the working environment and to the products being manufactured or processed. Every hydraulic fluid connection is viewed as a possible leak with unexpected, costly shut downs, ultimately delaying production. Engineers are also realizing that screw jack systems are generally easier to design and install. Screw jacks are more accurate, offering greater repeatability when compared to hydraulic systems. Finally, screw jacks ease the speed and positioning of the controlled systems.

• environmentally friendly
• safety and low maintenance (higher up-keep)
• ultimate precision and accuracy (repeatable results)
• cleaner solution, less clean-ups
• easier to design and install (fast setup)
