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
Features
1 - Undercarriage with expandable tracks from 2980 to 4480 mm by means of hydraulic cylinders
2 - Turret c/w DEUTZ TCD 2015 V06 diesel engine and sound proofed canopy, mounted on a 360° slew ring
3 - Winch assembly fixed by 2 pins each winch, for easy removal
4 - New design parallelogram system, especially shaped to fit crowd winch in transport condition. Allowing working radius adjustment always maintaining the mast in vertical position. C/w electronic device for automatic stop
5 - Self-erecting mast composed by an intermediate element 13,5 m long and a top element with 1,5 m extension. The max torque can be applied all over the mast length. Multipurpose design for cylinder and winch crowd system
6 - Sheave cathead with lateral mounted service rope pulley

8 - Rotary head with variable displacement motors and one high spin off speed. Two speed gear available (optional)
9 - Telescopic kelly bar with guide to mast, available with friction or mechanical locking type
10 -Self mounting type counterweight by means of hydraulic cylinders. It can be easily and quickly removed for transport purpose
11 -New design cabin with more ergonomic operato’s place
