Increase productivity in low- to mid-seam applications with an entry driver featuring an integrated bolting system, facilitating simultaneous cutting and bolting. This single-pass machine addresses the bottleneck during gate road development when the roof is weak, necessitating early roof bolt installation.
- Exceptional reliability and uptime
- Increased interval between major rebuilds (typically 3-6 years)
Product Features and benefits:
Dual Extendable Cutterheads
The mining equipment features hydraulic cutter head extensions that retract to facilitate easy withdrawals and enhance flexibility when cutting corners. The wide cutter head is capable of making cuts up to 16 feet in a single pass, providing exceptional productivity. The power at the cutter head is an impressive 656 HP/490 kW.
Faceboss Control System
Optimize your mining operation with actionable insights from the Faceboss Control System. This system provides operator assistance tools, automated sequences, advanced diagnostics, and machine performance monitoring. It is designed to enhance operational efficiency and decision-making.
Dual Roof Drills
For the quick installation of roof control, the equipment is equipped with two semi-automatic Joy AFX210 roof bolters with tilt capability. These drills are fixed at each side of the miner, ensuring efficient and effective roof bolting.
Front and Rear ATRS Cylinders
To ensure the safety of the operator, four hydraulic cylinders stabilize the roof during mining and bolting operations. Engaged with the push of a button, these cylinders constantly pulse to maintain contact with the roof during bolting. This feature enhances safety and stability during underground mining activities.
Hydraulic Optimization Package
Designed for ease of maintenance, the hydraulic optimization package enhances accessibility to components. It achieves this by minimizing hosing, simplifying hose routing, and reducing the number of components. This not only makes maintenance more straightforward but also simplifies the rebuild process, contributing to overall equipment reliability.
These features collectively contribute to the efficient and productive operation of the mining equipment while prioritizing safety and ease of maintenance.
