Rail Sleeper Bolt Anchor Extraction Drilling Machine
Product Overview
The rail sleeper bolt anchor extraction drilling machine is designed for precision drilling during railway sleeper maintenance and re-anchoring tasks. Certified by CRCC, this tool ensures reliable performance and safety compliance across various railway maintenance projects.
The machine uses a diamond-tipped hollow drill bit that creates smooth, vibration-free tapered holes (3:20 slope), providing strong pull-out resistance for reinstalled anchors. With a 1.2KW engine and 1000rpm output speed, it achieves high drilling accuracy even on dense concrete sleepers.
Weighing just 43kg, the equipment is ideal for tunnel works or narrow track areas where space is limited. The quick-clamping system and ergonomic handles help operators set up within minutes, improving efficiency during limited maintenance windows.
This railway drilling machine is widely used by maintenance teams in China Railway and overseas projects, ensuring consistent anchor strength and operational safety.
Key Features
- Tunnel-Optimized Design: Compact frame allows safe operation in confined and low-clearance spaces such as tunnels and bridges.
- Diamond Hollow Drill Bit: Ensures clean and precise drilling with minimal vibration, extending drill bit lifespan.
- Quick Positioning System: Adjustable clamps and guide rails allow setup within minutes, reducing track downtime.
