Description

The Hugh Smith Vertical Plate Bending Machine is designed for forming cylinders of various diameters, making it ideal for producing pressure vessels, boilers, nuclear plant components, and legs or piles for oil platforms and modular structures.
 

• • 3,000 Ton, handling plate width 13′ and thicknesses up to 7.87″ cold.
  • Designed to require minimal crane involvement while occupying a small footprint. Once the plate is loaded, no further crane attendance is needed.
  • Complete cylinders can be formed in 20 minutes or less, depending on diameter.
  • Plate edge pre-setting is easily achieved using the machine’s direct-acting hydraulic force.
  • Adjustable bending centers provide optimal conditions for processing a wide range of plate sizes and thicknesses.
  • Re-rounding and weld seam correction can be performed with ease.
  • Capable of forming cones, straightening plate, and—when equipped with a nose bar—performing heavy-duty flanging, including closed box sections.
