1. What are the primary applications of the MQT series Pneumatic Rotary Roofbolters?
The MQT-130/3.0 and other MQT series machines are designed for anchor bolt drilling and rotary roofbolting in underground mining and tunneling projects. They are highly efficient for drilling rock, coal, and semi-coal lanes.
2. How is the product quality guaranteed before shipment?
Quality is strictly maintained through a standard procedure of producing pre-production samples before mass manufacturing, followed by a final inspection of all mechanical, transmission, and pneumatic components before dispatch.
3. What are the key advantages of your mechanical and pneumatic systems?
With 20 years of research and design experience in mechanical, hydraulic, transmission, and pneumatic control systems, the products deliver optimal starting torque, reliable load capacity, and robust durability under high pressure.
4. What type of other machinery and parts do you specialize in?
Aside from rock drilling and mining roofbolters, the core capability includes robot chassis, Ackerman chassis, tracked chassis, wheeled drive chassis, and wall-climbing robots.
5. What air pressure range is optimal for operating these drilling rigs?
The recommended stress range is between 0.4 and 0.63 Mpa, with a rated pressure of 0.5 Mpa to achieve maximum torque and speed safely.
6. How does the gas consumption differ between the MQT models?
The load gas consumption ranges from ≤3.8 m³/min for the MQT110, ≤4.2 m³/min for the MQT120, up to ≤4.4 m³/min for the MQT130, ensuring high power output proportional to consumption.
