The orange body distinguishes the jack with torque of 4.5 Nm from the 12 Nm version (black) Part 4678.


The brake prevents any loss of position caused by external factors (e.g. vibrations); if you use the knob for movement, the brake will not fully lock the position in order to protect the internal transmission devices.

Maintenance: not required.

Standard pack: 1 piece.


Nominal torque transmissible: 4.5 Nm (the knob with torque limiter slips when reaching 4.5 Nm, protecting the reduction gear from overloads).

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 min at 60 rpm which corresponds to the complete rack travel of 470mm;

Manual drive , if motor-driven max. 60 rpm.
