Pneumatic Roof Bolter
This tool is called the Pneumatic Roof Bolter. It is a key device for coal mine tunnel support. It works well in tunnels with rock hardness f≤10. It is perfect for coal mine roof bolting. This machine can drill roof bolt holes and anchor cable holes. It mixes and installs resin anchor bolts and cables. It tightens the bolt nut in one step. The bolter uses compressed air. It is safe and explosion-proof.
A Key Tool For Mine Roof Support
The MQT-130/4.0 features higher power output than the MQT-130/3.2, with a rated power of 4.0 kW. It achieves a faster drilling speed and is particularly ideal for roadways with hard rock strata. The unit weighs between 51 kg and 55 kg, marginally heavier than the 3.2 model, yet this extra weight translates to superior working efficiency. Three height specifications (A, B, C) are offered for selection based on actual roadway heights.
Our company started in 2007. We have 20 patents. We serve large clients like China Energy.
Light and Safe with a Fiberglass Leg
The air leg is made of fiberglass. This material does not make sparks. It is safe and light. It resists wear. The maximum thrust is 8.2 KN. The Pneumatic Roof Bolter has a dual exhaust path. The leg retracts fast. After drilling one hole, you move to the next quickly. This improves work efficiency. Air consumption is 4.2 m³/min at 0.5 MPa. Most mine air systems can supply this. Flushing water pressure is 0.6-1.2 MPa. Our factory is 6,000 m². We have 50+ workers. We follow ISO9001. The tool has a 12-month warranty. We have a 24/7 after-sales team.
