Manufacturer: Roccia (Italy)

Model: HR4W-3016 (3000mm x 16mm)

Year of Manufacture: 2021

Bending Length: 10 Feet (3,100 mm / 120 Inches)

Maximum Rolling Capacity: 5/8 Inch (16 mm)

Maximum Pre-Bending Capacity: 1/2 Inch (12.5 mm)

Configuration: 4-Roll Double-Pinch Hydraulic Plate Roll with Vertical Overhead Sheet Support

Overview

Up for sale is a late-model, high-precision 2021 Roccia HR4W-3016 4-Roll Hydraulic Plate Bending Machine. Manufactured in Italy by Roccia—a world leader in heavy plate rolling technology—this 4-roll double-pinch plate roller offers a 10-foot (120") bending length with a 5/8" rolling capacity and 1/2" pre-bending capacity.

As seen in the provided image, this machine is equipped with a tall hydraulic overhead vertical sheet support (designed to prevent top-roll sag and diameter deflection when rolling large-diameter thin-gauge tanks or cylinders). Featuring induction-hardened rolls, hydraulic drop-end for easy cylinder removal, and modern CNC graphic controls, this unit provides maximum accuracy and high repeatability for tank, pressure vessel, and heavy structural fabrication.

Features & Machine Highlights

• 4-Roll Double-Pinch Advantage: The bottom pinch roll clamps the plate securely against the top roll, providing precise pre-bending on both leading and trailing edges without requiring sheet flip.
• Vertical Overhead Support Structure: The integrated heavy-duty vertical support beam (orange tower) holds large-diameter thin-wall cylinders erect during rolling, eliminating shell distortion and the need for overhead plant cranes.
• Induction Hardened Rolls: High-surface-hardness rolls allow the machine to process tough materials including stainless steel and high-tensile carbon plate without roll scarring.
• Hydraulic Drop End: Front housing drops hydraulically with a single control command to allow fast, axial removal of fully closed cylinders.
• Late-Model 2021 Condition: Clean, modern European machinery with low operational age and minimal mechanical/hydraulic wear.
