The hydraulic tensioning system is the only one able to guarantee the same tensioning on the whole diamond blade pack, optimizing the yield.

 The PTM’s voltage system is generated with two operations:

  1. the pre-tensioning of the special screws mounted on the tie rods with the help of the torque wrench;
  2. the final tensioning thanks by means of an oleodynamic pump.

This method guarantees the same tension on all the blades, moreover it is a faster and safer system, which does not require the continuous intervention of specialized technicians for manual tensioning.

The working tension is indicated by a single pressure gauge that shows the pressure in tons and bars. Furthermore, in the open frames, a compensation cylinder is installed to guarantee constant tension in all the working positions of the blade holder.

Our tensioners are divided into two lines:

  • CLASSIC LINE: characterized by a superior strength with cut starting from 15 mm;
  • KAMALEONT LINE: which allows, through the easy replacement of the joining side plates, a cut starting from 9 mm.

PTM’S TENSIONERS ARE TESTED AND DESIGNED TO OBTAIN THE MAXIMUM PERFORMANCE IN COUPLE WITH OUR TIE RODS.
