ACRA MACHINERY -Durma Hydraulic 4 Roll Plate Roll

The high torque drive system of Durma’s HRB-4 Roll Bending Machines allows them to achieve shorter cycle times whilst user friendly control units make it possible to be less dependent on operator competence.


4-Roll Plate Rolls are more precise, productive, versatile, faster safer AND easier to operator than 3-Roll machines & ideal for bending plate up to 200mm thick. Like the 3-roll variation, the HRB-4 also consists of a robust machine body to ensure long life repeatability and low maintenance.
