Core Technical Highlights
• Heavy-Duty Structural Design:
The main frame is welded using Q345B/Q355D high-strength structural steel, providing exceptional impact resistance and torsion rigidity for heavy infrastructure tasks.
• Induction-Hardened Wear System:
All critical components, including track rollers, idlers, and track shoes, undergo deep induction hardening (HRC 48-54). This ensures maximum service life when operating on abrasive rocky debris.
• Precision Maneuverability:
The compact footprint is specifically optimized for
confined tunnel spaces, allowing for a smaller turning radius without sacrificing stability or load capacity.
• Modular Customization:
As a direct manufacturer, we offer customizable track lengths, chassis widths, and hydraulic motor brands (such as Eton or Thalemus) to match your specific machinery requirements.
