Blast hole drilling machine crawler Used machinery Soilmec sr80

Application

The hydraulic drilling rig SR-70 is mounted on SOILMEC base carrier and has been specially designed for suiting the following applications:

● Cased bore piles with casing driven directly through rotary head or optionally by casing oscillator powered by the base carrier itself;

● Very deep bored piles stabilized by drilling fluid or dry hole;

● CFA piles by means of very long auger string; 

● CSP/CAP piles with double rotary; 

● Displacement piles;

● Soil-mixing; 

● Reverse circulation; 

● It can be converted to work with an hydraulic grab for diaphragm walls. 

The SR-70 is equipped with the DRILLING MATE SYSTEM (DMS) on 12” touch screen for monitoring and control of the operating parameters
