GSD series drill is mechanical drill head type well drilling machine, which is independently researched&developed and manufactured by our company. It can be applied for different geological situation, with these characteristics as portability, high efficiency and multi-function.

1. Drilling geothermal pump wells
2. Drilling wells for urban and rural life
3. Drilling wells for agricultural irrigation and industries
4. Drilling for geotechnical survey
5. Drilling construction engineering holes

1. It can be moved through the tractor or automobile and equipped with the device of hydraulic up-down tower, efficient and convenient;
2. Diesel engine driven; it can also be equipped with three-phase ac generators according to customer’s demands;
3. It can adopt both mud drilling and air drilling technology, and suitable for clay layer, sand layer and rock;
4. Power head with large torque and lifting force, easy operation, low cost and high yield.
