360° Deep Hydraulic Soil Test Drilling Machine/ Geotechnical Borehole Drilling
360° Deep Hydraulic Soil Test Drilling Machine/ Geotechnical Borehole Drilling
Product Feature:
ST-200 type soil test drilling rig machine is widely used for geological general investigation and exploration of railway, road, bridge, dam and tall building base, geological core drilling, small grouting holes, blasting holes, civil wells and earth central air conditioning wells,etc.
1. Compact structure, concentrated handle,small footprint, light weight, strong decomposition, and easy to move.
2. Feed by hydraulic cylinder, the drilling efficiency is higher and it can save labor.
3. The machine is equipped with our high technology taper clutch, it features strong torque transmission, easy operation and free maintenance.
4. Vertical spindle are fixed by four groups of bearings to ensure that the rotatory machine has enough rigid for gravel layer and other complex geological conditions.
