Product Overview
The AT-4000L Raise Boring Machine was developed to meet the evolving requirements of modern underground mining operations. Based on optimized rock-drilling parameters and an integrated system design, the machine features a more compact configuration and reduced overall height. Its integrated crawler travel system enables convenient relocation and improves maneuverability in confined underground tunnel environments.

Key Features

1.Fully Automatic Drill Rod Handling
The fully automatic drill rod loading and unloading system reduces manual handling requirements and improves drilling efficiency.
2. Automatic Hole-Guidance and Deviation Control
The automatic hole-guidance and deviation-control system helps compensate for drilling deviation caused by geological conditions and improper operating practices.
3. Dual Control Modes
The machine supports both wireless remote and wired control. Programmable control reduces manual intervention, simplifies operation, and allows operators to become familiar with the system after basic training.
4. Self-Propelled Crawler Travel
The self-propelled crawler travel system facilitates convenient and efficient machine relocation between working areas.
5. High Drilling Performance
The machine delivers high drilling efficiency with ample torque and pullback force. Its high-capacity configuration provides sufficient performance for raise construction.
6. High-Quality Hydraulic and Electrical Components
The machine uses high-quality imported electrical and hydraulic components. The hydraulic system adopts a German Linde closed-loop hydraulic system, providing efficient and reliable hydraulic power transmission.
7. Multiple Drilling Parameter Settings
Different gear settings allow the machine to match drilling parameters to different hole sizes and operating requirements.
8. Modular Integrated Design
The modular integrated design simplifies inspection, maintenance, and servicing while keeping the overall machine configuration compact. Its reduced dimensions improve maneuverability in confined underground roadways and working areas.
