Continuous flight auger (CFA) drilling rig CHF 50

pilingdeepdiesel engine

Overview
The CHF 50 is a compact piling rig dedicated to Continuous Flight Auger (CFA) applications, combining reduced operating weight with extended drilling capability for deep CFA piles.

Summary
Its compact footprint and optimized structure enable operations on sites with limited access or bearing capacity while allowing CFA piles up to 27 m deep using 21 m augers and pile diameters up to 1,000 mm. The machine is configured specifically for CFA technology to provide consistent pile quality and efficient cycle times.

Main features

• Dedicated to Continuous Flight Auger (CFA) piling technology
• Compact design for constrained or limited-access sites
• High drilling capability with comparatively low operating weight
• Single-technology focus for steady pile quality and productivity
