Argomento della richiesta:

The CHF 90 is a dedicated CFA piling rig, engineered exclusively for Continuous Flight Auger drilling where productivity, stability, and reliability are critical. Thus, the CHF 90 is fully optimized for CFA operations, ensuring efficient performance across the entire piling cycle.

The machine is equipped with a four-line pull system, supporting the construction of CFA piles up to 32.5 m deep using 27 m augers with extension. The parallelogram articulation system provides an extended working radius, allowing the machine to operate effectively across a wide drilling area without repositioning. Transport and site setup are simplified thanks to a compact transport configuration and automated rig-up functions, enabling fast and straightforward commissioning once on site.
