MOTORIZED OPERATION
Aleph series can be handled by any kind of motors. Nowadays it’s possible a direct motorization for some IEC flanges thanks to an innovative molding process able to shroud bolts in the carter. It’s possible to connect 4, 6 or 8 poles motors, while it’s not suggested to assemble 2 poles motors for not overpass 1500/1800 rpm input rotational speed. Power curves show, in case of unitary service factors and for single jack unit, the input power in function of the size, ratio, dynamic load and linear speed.

MANUAL OPERATION
The Aleph series can be manually operated.

ROTATION DIRECTIONS
The rotation directions and the respective linear movements are showed in the drawings below. In standard conditions, UNIMEC supplies screw jacks equipped with right-handed worm screw, to which the movements illustrated in drawings 1 and 2 correspond. Upon request it is possible to have a left-handed worm screw, to which the movements illustrated in drawings 3 and 4 correspond. The combinations between threaded spindles and left-handed or right-handed worm screw, lead to the four combinations listed in the table below.
