Unimec TP, Assembly Instructions Manual

Page: 13 / 64

Translation of the original instructions edited according
to annex I - 1.7.4.1
The jack is a mechanical transmission composed of a worm screw that
engages a worm gear coupled to a trapezoidal spindle. In TP models
the trapezoidal spindle translates; in TPR models it rotates and the
translation is made by an external nut. In both cases it is necessary to
provide an anti-rotation system.
