■ Machine combined design, for working with vertical and horizontal axis.

 

■ N° 3 driving rolls (all).

 

■ Fully hydraulic drive:

     Rolls driven by low speed hydraulic motor + planetary reduction gear.

 

■ Hydraulic adjustment of the two lower rolls independent of each other

    (double prebending).

 

■ Hydraulic unit with pilot operated check valves to maintain constant the lower rolls position during bending-phase.

 

■ All welded steel frame, monobloc type for added strength and rigidity, stress relieved after welding.

 

■ Shaft in alloyed high-strength chrome-nickel forged steel (heat treated), mounted on long life grease lubricated self-alignment spherical roller bearings.

 

■ Bending rolls in High Tensile alloyed Forged Steel, heat treated.

 

■ N° 2 Lateral guiding rolls, each one adjustable in four directions.

 

■ Total protection from overloads by hydraulic pressure relief valves.

 

■ Electric and Hydraulic equipment by first class European manufacturers.

 

■ Centralized control panel with low voltage control designed for "easy-service", portable

    to permit optimum location for operator convenience and safety.

 

■ Control panel with push button controls for all functions.

 

 

 

 

 

■ Device for spiralling or coiling of pipes and tubes with tooling for calibration of pitch and coils diameter .

 

■ CNC controls: FAST or STRADIVARI.

 

■ Rolls for pipes.

 

■ Rolls for square and rectangular tubes.

 

■ Rolls for rolling sections to diameters smaller than attainable with standard rolls.

 

■ Rolls for special shape sections.

 

■ Calibrating devices for repetitive works, accurate spiralling and coiling.

 

■ Elongated shafts for rolling wider sections.

 

■ Hydraulic pushing roll device to keep angle leg-in and leg-out (and other sections) firmly against the top roll.

 

■ High rolling speed for rolls rotation (turbo speed).

 

■ Special operating voltage or special electrics.
