Description

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:

  1. 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.

  2. Operator-Friendly Layout: Balanced chassis and articulated four-wheel drive provide good visibility, flexible, fast, and safe operation in narrow tunnels.

  3. High-Frequency Impact Drill: The stepped piston enables high-frequency impact for rock drilling, improving transmission efficiency, increasing drilling speed, and reducing tool consumption.

  4. Wide Operating Space & Automation: Considerable space and automatic functions allow the operator to focus on safe, fast, and accurate drilling.

  5. Maintenance Friendly: All components are well-protected and easily accessible for maintenance, ensuring long-term reliability.

Applications:
