Continuous flight auger (CFA) drilling rig CHF 90

piling

Overview
The CHF 90 is a machine dedicated to CFA (continuous flight auger) technology, developed specifically for continuous flight auger drilling where productivity, stability and reliability are essential. Fully optimised for CFA piling operations, the CHF 90 delivers high, consistent performance throughout the production cycle.

Operational features
The machine is equipped with a fourth-drum pull system, ideal for constructing CFA piles up to 32.5 m deep using 27 m augers with extension. The parallelogram articulation provides an extended working radius, allowing efficient operation across a wide area without frequent repositioning. Transport and setup on site are simple and fast thanks to a compact transport configuration and automated assembly functions, enabling quick, safe and intuitive commissioning.
