TBM 4 Column Single or Double Marble Block Cutter

FEATURES
Load-bearing structure composed of four vertical columns
joined together by crossbeams. Bridge-trolley unit lifted by means of four screws guided by sliders with slide blocks made of anti-friction material; the entire unit is protected by a stainless steel guard. Vertical movement is performed by means of a selfbraking gearmotor driven by inverter.
Large-sized shoulders with milled surfaces and hardened steel interchangeable tracks on which the disc-carrying bridge-trolley unit slides. Sliding takes place on roller cages in oil bath protected by PVC bellows.
The overhead bridge unit with a robust electro-welded steel structure in which two V-shaped guides have been formed for the trolley to slide on. A self-braking gearmotor driven by inverter is used to drive the trolley, fitted with a braking device positioned on the opposite side to the gearmotor to guarantee its correct and stable positioning during cutting. A rack and pinion with slanting teeth and corresponding inverter-driven gearmotor are used to translate the overhead bridge unit.
Disc-carrying trolley sliding on broad cross-section cast iron prismatic slide blocks in oil bath protected by special guards.
Movement is performed by means of a rack and pinion with slanting teeth and corresponding inverter-driven gearmotor.
110 mm disc shaft, for the use of 1 1600 mm diameter discs.
To guarantee a long service life and maximum resistance to corrosion, all the surfaces have been sand-blasted, galvanised and carefully painted with dual component epoxy paints.
