Based on different stratum, we can adjust torque and rotary speed of drilling rig to increase drilling rig’s adaptability. At the same time, we can adjust torque and rotary speed according to client's request.
With the crawler, it has the following technical features: fast mobility, accurate location, time saving, good reliability and stability. It can also reduce labor intensity and increase efficiency after equipping the clamping and breaking device.
Our R&D department also develops relative drilling tools to meet the following construction technology:
