300M Geotechnical Drilling Rig Machine for Core Drilling and Soil Sampling
ST-300 Geotechnical Drilling Rig Machine is multifunctional, mainly applied in constuction, highway, bridge, water conservancy, hydroelectricity, mine, tunnel and so on. It is widely used in engineering hole construction, such as foundation investigation hole, deep foundation pile anchor hole, road or dam foundation reinforcement holes, drain hole, open pit blast holes, water wells and foundation piles.
Features:
1. Decent gearing speed with large rotary range
2. Low speed drilling with large torque is suitable for piling work and drilling sampling.
3. Equipped with Hydraulic cylinders for traveling on frames, hence the rig is able to move freely at 300mm, which greatly facilitate lowering and lifting drill toolings.
4. Hydraulic feeding, easy operation, high drilling efficiency, less human efforts.
5. Compressed structure, small dimension, light weight
6. The rig has upper, lower chuck for reliable drilling rods tightening, able to adapt to different drill rods, drive pipe is not necessarily
required; lower chuck is arc shaped with strong clamping ability.
