TECHNICAL FEATURES
Shortest Flat End & Safer Operations
Achieve ultimate plate grip and safety through ideal torque transmission and precise roll synchronization.
All-Rolls-Drive Technology: Motorized top and side rolls guarantee optimum torque transmission and even power distribution between hydraulic motors.
Brakeless & Synced System: Eliminates mechanical brakes. Roll speeds are automatically and hydraulically synchronized for smooth operation.
Shortest Flat End: Precise positioning at the tangent point delivers the industry’s shortest possible flat ends on the final product.
Anti-Slipping Safety: Prevents any slipping or falling of the plate during the pre-bending phase, ensuring maximum workshop safety.
High-Accuracy Pre-Bending: Motorized rolls allow the top and pinching side rolls to almost overlap, granting the highest accuracy.
Superior Re-rolling Performance
The market’s sturdiest and most compact frame acts as the robust backbone, transmitting all forming stresses efficiently to the foundations.
Heavy-Duty Compact Frame: Offers maximum rigidity and stability, allowing the machine to withstand heavy-duty plate forming with ease.
Increased Side Rolls Stroke: The robust structural design maximizes the side roll stroke and interaxis distance for wider application ranges.
Shallower Pit Construction: Built-in reinforcement beams (intra-frame design) eliminate bulky base platforms, significantly reducing foundation pit costs.
Superior Cone Bending Capacity
Guarantees unparalleled performance and speed in continuous cone rolling operations.
Fully Tilting Rolls: Three fully tilting rolls make complex cone bending operations exceptionally accurate, smooth, and swift.
Stress-Free Tilting: Pendular shaft-mounted gearboxes allow stress-free roll tilting up to 100 mm per 3 meters of roll length.
Maximum Precision
Engineered to deliver ultimate forming accuracy and maximum equipment durability under any production environment.
Frame-Mounted Cylinder Cans: Cylinders rest on thick frame plates instead of weak bolts, maximizing available force to roll tight cans.
Full Hydraulic Symmetry: Achieves perfect rolling accuracy without constant electronic adjustments, vastly increasing component durability.
Even Load Distribution: Equal “push-push” or “pull-pull” cylinder forces at both ends guarantee a perfectly uniform load along the forming plate.
