ELE.FANTINI S.r.l. designed a new series of LINEAR ACTUATOR for moving medium and high powers with loads up to 6 tons.
Working range is from 3.250 N to 60.000 N; speed from 3,7 to 150mm/sec.
These linear actuators are avalaible in the following versions:
ALCT type: coaxial, with epicyclical straight toothed reduction gears.
ALVT type: orthogonal, with worm screw and helical crown reducer; this model can be coupled in series with perfect synchronisation of operation.
Main feature of these lineators is the use of ball screws that, owing to their high efficiency (90-95%), give the following advantages:
- limited power demand that results in a reduction of torque at the rotating axles and corresponding specific pressures on gear teeth.
- lower heat production and, as a result, higher operating frequency (ED%)
- lower consumption of moving parts and, therefore, longer life of parts.
- smooth linear movement without vibrations.
Linear actuators ALCT – ALVT are supplied with adjustable limit switches and potenziometer for monitoring the stroke.
All machines are equipped with a self-braking motor so as to make the sistem irreversible.
