Characteristics: the synchronised movement of the two jacks occurs by means of the hexagonal synchronisation and transmission shaft. Permanent setting is assured by a brake that prevents any loss of position caused by external factors (e.g. vibrations).


in order to protect the internal transmission devices, if you use the knob for movement, the brake will not fully lock the position.

Maintenance: not required.

Nominal torque transmissible 12 Nm (4.5 Nm version on request).

Rack's travel per turn: 1 knob turn = 8 mm of rack travel.

Reduction ratio i=16 (16 knob turns -worm screw- are equivalent to 1 turn of the worm gear with hexagonal seat).

STEP-BY-STEP (NO Continuous operation).

On/off ratio=1/30

Maximum uninterrupted operation: 1 minute at 60 rpm, which correspond to a complete rack travel of 470mm;
