crawler hydraulic rotary drilling rig SR200M
Kelly system or CFA system to enlarge construction scope ……
With six years of rotary drilling rig designing and manufacturing, understands that, one drilling machine must be able to fulfill different construction requirements and keep the highest working efficiency, M series rotary drilling rig is exactly developed based on this idea.

CFA Convenient shift between Kelly drilling and CFA drilling Modular designed working equipments make the switching between Kelly drilling and CFA drilling simple and easy.
CFA drilling process
Move the rig to the located pile position. 2. 3. Drill to the planned depth. 4. Pump concrete through the hollow stem of the auger while extracting the auger. 5. Hoisting the reinforcing cage into the pile.
High Reliability Wide application range, high reliability High quality key parts Adopt world famous brands like CAT, Rexroth, Brevini and Bonfiglioli.
High-strength steel Mast strength increased by 30% Mast shock-absorbing capability increased by 35% New materials promise high mechanical capability.
Experiment & Test system Perfect Experiment & Test system guarantees that all rotary drilling rigs feature the same high quality
