HF-20 man portable hydraulic drilling rig for geotechnical exploration

HF-20 portable hydraulic drilling rig

HF-20 is a kind of multi-function portable hydraulic drilling rig optimized constantly by us, it use gasoline engine (or diesel engine or electric motor) as power , to achieve the large load change need rely on hydraulic driven gyrator and cylinder pressure adding, reliable running. Choose the diamond alloy or calyx bit based on the actual geological situation. Practice rod as non-stop, high efficiency.

Features:

1. Central handles, simple operation, easy to learn and understand, reliable and practical.

2. Compact structure, small valume, light, easy to disassemble and move, fit in flat and mountain areas.

3. Reliable function, complete coring, flexible operation, fit for field work, improve the efficiency, cut sampling cost, it reaches global advanced level.

Widely used in geological survey sampling and mapping, seis hole construction, geochemical rock sampling, road foundation exploration and geotechnical engineering etc.
