Continuous flight auger (CFA) drilling rig CH 36

geotechnicalpilingdeep

Description
The CH 36 is the largest-size model in the Comacchio multifunction piling rigs range, engineered to combine strong performance and operational flexibility. Indicative operating weight: approx. 97 tonnes. High-torque / high-speed rotary head capable of delivering up to 360 kNm of torque, supporting piling and ground-improvement methods such as Kelly piles, CFA (Continuous Flight Auger), displacement piles (DP) and soil mixing (SM). The machine is offered in multiple configurations to ease transport (demountable components: crawler side frames, modular ballast and other structural elements to adapt to logistics).

Key features

• Max nominal torque: 360 kNm (265,500 lbf-ft)
• Rotary head speed: 60 rpm
• Engine power: 345 - 405 kW (463 - 543 HP)
• Winch System (WS) pull/push: 486 kN (109,250 lbs)
• Main winch pull: 300 kN (67,440 lbs)
• Auxiliary winch pull: 133 kN (29,900 lbs)
• Operating weight range: 95.5 - 102.5 t (210,540 - 225,970 lbs)
