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 7 - Crowd system by means of 6,5 m stroke hydraulic cylinder or 16,5 m stroke winch (2nd line pull) 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
