Overview & Heavy-Duty 3-Roll Mechanical Principles

The W11 Series Hydraulic 3-Roller Plate Bending Machine with Motorized Top Roll Lifting is an industrial mechanical and hydraulic plate rolling solution engineered for medium to extra-thick sheet metal and heavy plate curving. Widely utilized across boiler manufacturing, pressure vessel fabrication, shipbuilding, mining machinery, and steel structures, it handles plate thicknesses ranging from 4 mm up to 25 mm with processing widths reaching 3200 mm.

Featuring high-torque mechanical drive rotation and motorized vertical elevation for the central top roller, the machine ensures continuous, slip-free feeding. The upper roller can be electrically lifted and disengaged at the drop end, allowing operators to rapidly extract fully closed cylindrical shells with zero structural hindrance.

Precision Structural Features & Power Transmission

• Motorized Upper Roll Lifting: Separate auxiliary motor and screw lifting system allow rapid, symmetric vertical positioning of the top roller, significantly reducing setup time between passes.
• High-Module Synchronous Spur Gears: Heavy-duty open side gears and enclosed worm reducers distribute immense rolling torque directly to the two bottom drive rolls, preventing heavy plate slippage under maximum load.
• Drop-End Unloading Mechanism: The manual or hydraulic drop yoke releases smoothly, allowing the upper roller to be balanced for quick extraction of finished cylindrical cylinders.
• Angle & Profile Bending Capability: The roller shafts can be extended on the machine side to accommodate custom profile dies for rolling angle steel, flat bars, round tubes, and channels.
