HEAVY DUTY WIDE SPAN
CNC Heavy Gantry Plasma and Flame Cutting Machine
Engineered for high-tonnage fabrication yards, bridge builders, yellow goods manufacturing, and shipbuilding dry docks. The CNC Heavy Gantry series features a box-welded, stress-relieved gantry crossbeam spanning up to 6000mm. Dual-side synchronized AC servo motor drives paired with high-precision planetary reducers ensure zero-backlash precision while running multiple heavy flame and high-definition plasma torches simultaneously across thick steel plates.

Cutting Capacity Across Material Grades
Engineered to slice through massive structural plates with strict perpendicularity and minimum thermal warpage.
Why Heavy Industries Rely On Our Gantry
Built for continuous round-the-clock structural profiling in high-demand industrial environments.
Stress-Relieved Box Girder
Manufactured from thick steel plate box-welded beams annealed at high temperatures to prevent thermal deflection across 6-meter spans.
Dual-Side AC Servo Sync
Bilateral high-torque Yaskawa/Panasonic servos synchronize both master and slave trucks with zero mechanical backlash along 30-meter rails.
Multi-Torch Simultaneous Cut
Equip multiple oxy-fuel strip torches alongside an HD plasma torch to slice parallel structural flanges and web plates simultaneously.
Advanced Beveling Option
Supports optional automatic 3-torch V, Y, and K beveling heads for instant weld-edge prep on heavy pressure vessels and ship hulls.
