ST50 series are the simple rigs suitable for borehole drilling in geo-construction and geo-technical exploration drilling, and mountain area drilling in projects like civil building, railway construction, hydropower, highway, bridge and dam etc. Mainly used for:SPT working / Diamond Core drilling / Soil sampling with auger drilling (SPT) / Micro piling / Water well drilling by carbide and rotary drilling
Specially recommended
1, Drilling depth can reach 50m.
2, Steels quality is good, torque is large.
3, Easy operation, free-maintaining.
4, For various complex strutam, such as pebble bed, aggregate bed.
5, Saving money, compact construction, easy moving.
6, For geological exploration, exploration of high building construction, riversconstruction, civil water well.
7, It can do standard penetration test, use auger drilling and sampling with solid stem and the triple rod jet grouting.
Small hydraulic drilling machine Mini geological exploration drilling rig advantages
1. Used for general investigation, geophysical exploration, high-way and building construction, and blast-hole drilling etc.
2. With hydro-automatic feeding device, and high drilling efficiency.
3. Designed with hydro-chucking unit instead of slips to ensure drilling from stop when changing pipes.
4. Close levers, convenient to operate, safe and reliable operations.
5. Compact in structure. All the drill, water pump and diesel engine installed on one base frame result in space-saving.
6. Light in weight, easy disassembling for transportation and applicable to working conditions in plain and mountain areas.
