Rotary Drilling Rig

Features of Rotary Drilling Rig
1. Equipped with Cummins series turbocharged engine, our rotary drilling rig features high quality and stable performance.
2. With an extensible and flexible chassis, the rotary drilling rig improves its stability.
3. Our rotary drilling rig is compatible with short auger bits, common drill bits or core bits.
4. With the leveling system from Shanghai PalFin Co., Ltd, SD series rotary drilling equipment operates well.
5. Our rotary drilling adopts hydraulic transmission control system, which can control the power load in time.
6. The tower is composed of three section foldable backstay. Its height can be adjusted during transportation.
7. Friction Kelly bar and interlocking Kelly bar are available. You can get either of them installed in this engineering machinery.

Applications of Rotary Drilling Rig
Our rotary drilling rig is a mobile drilling rig, which is proved to drilling in many strata such as clay, unconsolidated soil, sand soil, silt stratum, backfilled earth, the stratum of gravel, weathered rock and frozen ground, etc.
