HR-3 Series

Planetary Type Hydraulic Three Rolls

HR-3 Series 3 Roll Bending Machine

Our HR-3 series hydraulic 3 roll plate bending machines usually ideal for obtaining large diameters. Large diameter cylindrical bends used in silos, oil and water tanks, feed and grain bins can be made easily on these machines. The symmetrical 3-roll arrangement allows pre-bending to both ends of the plate if required. Although the bending process is slower than 4 roll machines but all kinds of profiles can be bend on these machines as well as plates due to the greater pass through.
