Screw jacks generally work in high load applications. Competitive technologies at high loads tend to be hydraulic devices. However, the hydraulic system is more energy efficient than the electro-mechanical operation provided by the screw jack. Hydraulic systems waste energy as the fluid circulates at a constant pressure, regardless of the amount of work that must be done with the hydraulic positioning.
