Specification :

GS-20/ GS-18 Engineering Drilling Rig, Water Well Drilling Rig
Advantages
1. GS-20, GS-18 drilling rig is manufactured with large portal frame, and the frame-elevating and the main equipment transfer are both hydraulically controlled.
2. The large modulus, hyperboloid rotary table comes with large torque. This, coupled with dual-winch, ensures the reliable performance and long service life of the drilling equipment.
3. This engineering drilling rig is applicable for both directional and reverse circulation drilling methods. This makes the equipment suitable for use in different geological conditions.
4. The key components, like winch, rotary table, gearbox, and drill tower, etc. are all manufactured in-house, which ensures both reliability and timely supply.
5. Simple to use, convenient for maintenance, low cost.

Applications
With a wide range of advantages, this engineering drilling rig is commonly used in the construction of railways, bridges, ports, dams, and deep water wells, and more.
