The design of the CH 150 is based on the use of an excavator base carrier (in the 8-10 tons weight class) equipped with a modular drilling mast and a multipurpose rotary head. The extended reach of the boom combined with the mast rotation movement, ensures that the CH 150 can be used to perform a wide variety of positions covering a large work area. The stability of the machine even at its maximum reach is granted by the variable-width undercarriage. The machine features two powerful winches and a muiltipurpose rotary head providing up to 43.7 nominal kNm torque. The modular mast design allows the use of kelly bars of up to 9 elements and 3.5 m in length to achieve depths of over 25 m. In CFA configuration, the CH 150 can reach 11.9 m pile depth, thanks to the use of a special extension. In addition to the kelly and CFA set-up, the machine can be configured for micropiles installation. The cabin and the controls of the CH 150 are optimized to operate in confined spaces with the goal to guarantee great ease of use and manoeuvrability in any site condition, with a view to achieve maximum comfort and safety for the operator.
