Soilmec SR-90 TTJ Hydraulic Rotary Rig - Twin Turbojet for soil mixing

Following the positive global market feedback, Soilmec proposes the SR-90 in a new configuration: the TTJ Twin Turbojet. This new solution for soil mixing consists of double TJ string mounted on the same rig designed for best breaking-up and mixing of the soil and for maintaining the vertical direction of the treated panel. The second gear can range from: 126 kNm @ 16,7 rpm to 36 kNm @ 58 rpm. The depth of the rig will reach 24.5 m using two 1,600 mm diameter tools. The distance between the two drilling axis is adjustable from 1,200 mm to 2,000 mm. An important innovation introduced on this new model is the DMS monitoring system combined with an innovative GPS positioning system for drilling works. Further more, the SR-90 TTJ is provided with a system suitable for dialoguing by radio in order to operate the controls' rear-action of the high pressure Soilmec pump.
