The innovative double-beam bed structure features a horizontal design and a self-developed stopper plug-in system, providing a low center of gravity and high load-bearing capacity for stable and reliable cutting of heavy pipes. This system offers versatile pipe cutting capabilities, adapting to various conditions and handling both standard and complex shapes across different pipe types. Its ultra-long movable gantry design supports extended workpieces, accommodating pipe lengths of up to 12 meters. Additionally, the integrated follow-up support device enables real-time adjustments to lifting height, preventing pipe swinging and sagging for precise cutting accuracy. The follow-up unloading device further enhances safety and convenience, significantly boosting overall production efficiency.
