Hydraulic 3-roll bending machine

RBD-3HL





These state-of-the-art hydraulic 3 roll benders use just top brand components like Siemens, Rexroth, Bosch, Parker, Atos, Telemechanique, SKF, NSK and FAG to ensure top lifelong performance. Over 50 years of experience in sheetmetal bending and thousands of reference customers will guarantee you first class support in any application or maintenance question. With our optional extras you can upgrade the level of automation, which will raise your production and flexibility. Our machines are widely used in shipbuilding, tank and truck industries. Also in the wind-power sector,food and construction sectors.

  • For medium and heavy bending tasks
  • The frame of solid welded construction
  • All rolls are mated of high-quality, heavy-duty ball bearings, which ensures minimum friction and even rotation of the bending rollers
  • Hydraulic roller is driven by independent drive motors and planetary gearboxes
  • As the planet gears are mounted directly on the rollers, the transmission of force without force or power loss
  • The simultaneous use of torsion bars and hydraulic units ensure maximum machining accuracy and production flexibility
