ST50 is a simple rig 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. Typically, it is mainly used for:

• SPT working
• Diamond Core drilling
• Soil sampling with auger drilling (SPT).
• Micro piling
• Water well drilling by carbide and rotary drilling

50 Advantages of drilling rig:

Compact in size and light in weight (Total weight without power unit is less than 260kg, it can be further disassembled), and it is easy to be carried and transported in difficult mountain working sites.Movable skid base, the drilling spindle could move away from the borehole easily;With a hydraulic auxiliary winch, it could help lift the drill rod and SPT tools, convenient for working

Features:

ST50 series hydraulic drilling rig is a light weight drilling rig, widely used in general geological 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, Fed by hydraulic cylinder, the drilling efficiency is higher, and it can save labor.

2,Equipped with national patented technology-taper clutch, it could achieve strong torque transmission, easy maintenance and free maintenance.

3,Vertical spindles are fixed by four groups of bearings to ensure that the rotator has enough rigid for gravel layer and other complex geological conditions.
