Screw jacks lifting system structures include miter gearboxes, screw jacks, electric motor or gear reducer, hand wheel, pillow block bearings, jaw couplings and line shaftings.
Compared to fast speed hydraulic lifting system and pneumatic lifting system, screw jacks lifting system is not only for the simple load-supporting from several kilograms to heavy duty several hundreds tons, but also have many advantages such as self-locking without brake or locking mechanism, precisely positioning, full synchronization, manual operated or electric motor driven, quiet environment, easy installation and operation, maintenance free. 

Screw jacks system efficiency 
When we choose multiple screw jack system,we should consider the efficiency.
The arrangement efficiency allows for misalignment due to slight deformation of the structure under load, for the losses in couplings and bearings, and for a normal amount of misalignment
in positioning the actuators and gear boxes. We use the following efficiencies (all standard units):
Two Worm Screw Actuator Arrangement - 95%
Three Worm Screw Actuator Arrangement - 90%
Four Worm Screw Actuator Arrangement - 85%
Six or Eight Worm Screw Actuator Arrangement - 80%
Notes: don't ignore bevel gearbox efficiency 98%
