Application and Features:
The KJ321 hydraulic tunneling drilling rig is suitable for drilling tunnels with cross-sections ranging from 12–45 m², capable of vertical, inclined, and horizontal drilling, as well as blast hole and rock bolting operations.
Key Features:
Flexible Drilling Boom: Equipped with flexible booms in two symmetric rectangular coordinates; 360° rotation and self-leveling beam make drill positioning easy. Suitable for lateral cross-cut and rock bolting drilling.
Operator-Friendly Layout: Balanced chassis and articulated four-wheel drive provide good visibility, flexible, fast, and safe operation in narrow tunnels.
High-Frequency Impact Drill: The stepped piston enables high-frequency impact for rock drilling, improving transmission efficiency, increasing drilling speed, and reducing tool consumption.
Wide Operating Space & Automation: Considerable space and automatic functions allow the operator to focus on safe, fast, and accurate drilling.
Maintenance Friendly: All components are well-protected and easily accessible for maintenance, ensuring long-term reliability.
Applications:
Underground tunnel excavation for mining, metro, highway, and railway projects.
Drilling operations in narrow or complex tunnel environments.
Rock bolting and stabilization in underground construction.
