The CH 850 is a multipurpose large diameter piling machine with an operating weight of approximately 90 tonnes. Delivering up to 360 kNm torque, the machine stands out for its exceptional torque/weight ratio. The CH 850 is equipped with an extendable carriage with removable side frames, which allow for reduced transport dimensions and weight. The latest generation engine, combined with an innovative hydraulic system, makes the CH 850 a highly efficient machine, with consequent advantages in terms of consumption and emissions. The CH 850 is designed to cover a wide range of operations including Kelly piles, continuous flight auger piles (CFA piles), displacement piles and soil mixing. The machine is currently available in the WPD (winch pull down) configuration and can be equipped with kelly bars up to 445 mm, reaching a maximum depth of 90 m. The CH 850 can be converted for CFA drilling, using augers up to 1200 mm in diameter and reaching a max. depth of 28 m.
