The CHF 50 is a compact CFA piling rig developed exclusively for Continuous Flight Auger applications, offering an exceptional combination of low operating weight and high drilling capability.

Its lightweight yet robust structure makes it a highly efficient solution for projects where site access, ground bearing capacity, or transport limitations are critical factors, while maintaining the stability required for deep CFA piling. It allows the installation of CFA piles up to 27 m deep, using 21 m long augers, with pile diameters reaching 1,000 mm. By focusing on a single drilling technology, the CHF 50 provides high productivity, consistent pile quality, and reduced operating costs.
