Screw/Nut system
The SEFAC screw/nut principle is inherently irreversible as the angle of inclination of the screw pitch does not allow the fork to go down without the operation of the motor gearbox.
Technologies
Ball screw
With the ball screw system there is no energy loss from friction and your SEFAC columns can achieve an efficiency of over 90%, reducing your electricity consumption.
Wireless
SEFAC has developed its wireless technology to optimize the operation of their column lifts and simplify their use.
