1. The drilling rig adopts engineering crawler and hydraulic walking chassis. It is convenient to move. It is more suitable for plains, plateaus and hills. The chassis has 4 legs, and the drilling machine has small vibration and good stability during drilling.

   2. The reverse circulation drilling rig is multi-functional, all key components are cost-effective products, and the system is equipped with pressure protection and alarm devices.

   3. The handles and instruments of all the actuators of the reverse circulation drilling rig are on the operation table, and the operation and control are convenient and reliable.

   4. The reverse circulation drilling rig adopts a unique drill frame and drill. The process is large, the torsion resistance is large, the structure is simple, the maintenance is convenient, the relocation is convenient, the operation of the orifice is convenient, and the drilling of the large top angle can be constructed.
