The tensioner used to tension the blades for cutting granite blocks and installed on granite gangsaws is an hydraulic modular device (patented) especially designed to distribute the same tension on all blades of the gangsaw. So, it avoids all the manual tensioning procedures with the great advantage of easily equipping and discussing the gangsaw. Hydraulic tensioners for granite are available in 8mm and 10mm minimum cut with three rains of pistons and for 15mm and 20mm minimum cut with two rows of pistons.
The hydraulic device used to tension the blades of the gang-saws for cutting marble blocks has been designed to keep constant and uniform the tension of blades in order to obtain perfect planarity of the cut.
9 tons Marble tensioner
Normally the blades of the marble tensioners are tensioned by 10 tons. Officine Marchetti produces several kind of 9 tons marble tensioner according to the thickness of the slab you want to obtain:
13 tons Hydraulic tensioner
The modern demand for the tensioning of the blades leads Officine Marchetti to design a new kind of tensioner with a load of 13 tons. The possible by this tensioner is the 15 mm.
Officine Marchetti produces different tie-rods according to the thickness of the slabs required.
