PR-G Ground Rail Fiber Laser Cutter
The PR-G is a massive ground rail gantry laser cutting system. Equipped with an ultra-long processing stroke, it handles the most demanding ultra-long and ultra-thick metal plates. With its low-profile, no-top-frame design, overhead cranes can easily load heavy sheets without obstruction. Ideal for shipbuilding, bridges, and heavy steel structures.
Key Engineering Advantages
- Ultra-Long Stroke: Ground rail moving structure processes 10m+ long plates in one setup, eliminating re-clamping.
- No Top Frame: Low-profile design allows overhead cranes to hoist massive plates directly onto the table safely.
- Massive Load Capacity: Ground rail foundation ensures extreme rigidity and zero deformation even under heavy loads.
- Multi-Station Operation: Supports simultaneous loading on one side and cutting on the other, maximizing uptime.
- 60kW Ready: Compatible with ultra-high power sources for stable thick plate piercing and clean cuts.
- Global Standard: Supports OEM, neutral packing, and CE kits for heavy-industry overseas buyers.
Built for Extreme Large-Scale Fabrication
🏗️ Ground Rail Foundation
Unlike standard gantries, the rails are mounted directly on the factory floor. This provides superior load-bearing capacity for massive steel plates.
🚧 No Top Frame Design
The absence of a cross-beam on top allows overhead cranes to easily drop heavy, oversized plates onto the cutting bed from above, saving time and increasing safety.
🔄 Multi-Station Setup
You can divide the long ground rail into multiple working zones. While the machine cuts in Zone A, the crane can safely load materials in Zone B.

Frequently Asked Questions
How does the lack of a top frame help?
Without a top frame, the machine allows overhead cranes to easily load massive, ultra-heavy metal plates directly onto the cutting bed from above, greatly improving safety and efficiency.
What is the maximum length it can cut?
The ground rail structure allows for ultra-long strokes. Standard options go up to 16 meters, and we can customize even longer rails based on your specific factory layout.
Does the ground rail require a special foundation?
Yes. Because of the massive weight of the gantry and the plates, we will provide a detailed civil engineering drawing. The factory floor needs to be reinforced with concrete foundations for the rails.
