Product selling point

Roadheader (Mine-Used Crawler Tunnel Milling Excavator): Product Introduction

Also commonly referred to as a milling machine, this equipment is engineered for efficient tunneling and excavation tasks, with wide applicability across the following projects:
  • Water conservancy projects
  • Subway construction projects
  • Mine tunneling projects
  • Coal mining operations
Core Functional Features
  1. Explosive Savings
Eliminates the need for traditional explosive blasting in tunneling, reducing material costs and minimizing potential safety hazards associated with explosive storage, transportation, and use.
  1. High Work Efficiency
Adopts optimized cutting and tunneling mechanisms, enabling continuous and stable operation. It significantly shortens project cycles compared to manual excavation or low-efficiency equipment.
  1. Enhanced Safety
Reduces manual exposure to high-risk environments (e.g., unstable tunnel walls, dust pollution, and blasting-related risks). This lowers the probability of work-related accidents and improves on-site safety standards.
  1. Superior Working Surface Formation
Features precise cutting control, ensuring the excavated working surface is smooth, regular, and well-formed. This reduces the need for follow-up trimming work and enhances the overall quality of the tunnel or working space.
