W11S Variable
Geometry Plate
Rolling Machine
The W11S series variable geometry plate rolling machine combines a vertically moving upper roll with two independently adjustable lower rolls, giving heavy fabrication shops a wider forming range for thin plate, thick plate, cones, and large shells.
Heavy Plate
Rolling Power
W11S is engineered for demanding plate rolling where operators need adjustable geometry, high forming force, accurate pre-bending, and stronger control over large workpieces.
Heavy Plate Range
Reference W11S configurations cover rolling thickness from light 4mm plate up to heavy 160mm applications for large fabrication projects.
Wide Working Width
Listed models support working widths from 2000mm to 4000mm for tanks, vessels, towers, large ducts, and heavy cylindrical shells.
Variable Lower-Roll Span
The two lower rolls move horizontally to change the support span, helping the same platform adapt to both thin plate control and thick plate forming force.
Hydraulic 3-Roll System
Hydraulic movement of the upper roll and lower rolls supports controlled pre-bending, rolling, calibration, and cone rolling workflows.
Variable Geometry Structure
W11S changes the distance between the two lower rolls to match plate thickness, material behavior, and minimum rolling diameter requirements.
The upper roll moves vertically while the two lower rolls move horizontally. A narrow lower-roll span improves thin-plate grip and reduces slipping, while a wider span supports higher bending force for thick plate rolling.
The variable geometry layout brings the forming point close to the clamping area, helping reduce straight ends during pre-bending on thick plates, shells, and vessel components.
By changing the lower-roll distance, W11S can handle different plate thicknesses more flexibly than fixed-geometry three-roll machines, making it suitable for shops with mixed heavy fabrication work.
Cone rolling packages help form tapered shells, hoppers, funnels, and transition sections by controlling plate guidance and roll positioning across the workpiece width.
The W11S platform is suited for wind tower sections, pressure vessel shells, large storage tanks, shipbuilding parts, bridge structures, and heavy industrial fabrication.
Control the Rolling Geometry
Lower-Roll Span Adjusts to the Job
Operators can set a tighter lower-roll distance for thinner plates that need grip and control, then open the span for thicker plates that need higher bending leverage and reduced forming stress.
This is the main advantage of variable geometry compared with fixed lower-roll layouts.
Programmable Hydraulic Positioning
PLC or CNC control can coordinate upper-roll and lower-roll movement, store common forming sequences, and help operators repeat large-diameter shells with more predictable results.
Useful for pressure vessels, wind towers, and multi-shift heavy fabrication.
Rounding and Calibration Control
After initial rolling, hydraulic roll positioning helps correct roundness and calibrate large shells. This reduces rework when tight fit-up is required before welding or assembly.
Important for shells that must meet downstream welding and assembly tolerances.
Configure for Heavy Fabrication
Add support, control, and forming packages to match W11S to heavy plate production, cone rolling, wind tower work, and large shell handling.
Recommended for wide, thin, or large-diameter shells.
A hydraulic top support helps hold large-diameter shells as they close, reducing sagging and improving operator control during final rolling and calibration.
Helpful for tanks, vessels, and heavy industrial cylinders.
Side supports assist feeding and shell handling when the plate is heavy, long, or difficult to balance, helping reduce manual handling during repeated passes.
Specify minimum and maximum diameters when requesting a quote.
Cone rolling equipment guides tapered parts and supports different rolling radii across the plate width for hoppers, transition sections, and conical shells.
Built around heavy plate, large diameters, and repeat shell quality.
For wind tower work, W11S can be configured with higher-duty hydraulics, CNC positioning, support devices, and workflow options for large shell production.
Final configuration should match duty cycle, site voltage, and local safety requirements.
Emergency systems, hydraulic overload protection, oil cooling, and production-duty electrical packages help maintain stable operation in demanding rolling environments.
