Diesel engine drilling rig SR-75

rotaryreverse circulationconstruction

Soilmec rigs are self-mounting, easily transportable and designed to giving the best drilling solutions. The hydraulic drilling rig SR-75 has been specially designed for suiting the following applications: - LDP cased bore piles with casing driven directly by rotary head or optionally by casing oscillator powered by the base carrier itself; - LDP deep uncased bored piles stabilized by drilling fluid or dry hole; - LHR (Low Head Room) – large diameter bored piles; - CFA (Continuous Flight Auger) piles by means of long auger string; - CAP (Cased Augered Piles) piles with double independent rotary system; - DP (Displacement Piles) / TCT (traction compacting tool); - TJ (Turbojet®) / TTJ (Twin Shaft Turbojet) - soil consolidation; - RCDS (Reverse Circulation Drilling System) on demand. The SR-75 is equipped with the DRILLING MATE SYSTEM (DMS) on 12' touch screen for monitoring and control of the rig performances and operating parameters.
