Description

Vertical Plate Bender / Vertical Press Roll
Manufacturer: Hugh Smith Machines (Qualter Hall & Co. Ltd.)
Application: Heavy-duty metal bending, shaping, and pressing especially for shipbuilding, pressure vessels, and large-scale fabrication.

Key Specifications (Typical for 3000-ton class machines)

Pressing Force: Up to 3000 ton
Maximum Plate Width: 4 meters
Maximum Plate Thickness:

At full width: ~75½100 mm (depending on material and radius)
At reduced widths: up to 145 mm

Roll Configuration: Vertical press roll with 3-roll system
Roll Diameter: Typically around 23 inches (varies by model)
Beam Structure: Heavy-duty top and bottom beams with variable camber gear to offset deflection under load
