The main advantages of electric worm gear screw jack are:
· Accurate and smooth delivery of force.
· Increased range of actuation as the stroke position is easily and quickly varied.
· Electro-mechanical solutions are more resistant to temperature variations.
· Complete control of the entire motion profile using standard control methods.
· Repeatable and accurate positioning.
· The electro-mechanical screw jack is generally cheaper when compared to a hydraulic system when the required ancillary hydraulic equipment is included.
· Machinery requires less maintenance as no hydraulic oil to maintain, no leaks to repair.
· Less manual intervention on machinery to set up processes as electro-mechanical solutions can be controlled over the complete motion profile.
· Reduced downtime caused by hazardous fluid leaks.
· Electro-mechanical solutions only use power when moving the load. In comparison hydraulic systems generally have to maintain pressure levels to either maintain position when holding a load or to ensure that the system can respond when required.
· In the event of power loss, screw jacks can be self-locking.
· No high pressure oil leaks.
