CH 650

The CH 650 is a multipurpose drilling rig mounted on a dedicated excavator carrier with an operating weight of 70 tons. The rig is self-erecting and can be transported with minor disassembly of the machine, thus allowing for easy and fast rig-up. The CH 650 is designed to cover a wide range of drilling technologies that include bored piles, continuous flight augers (CFA piles), displacement piles and soil mixing. The machine can be supplied in the CPD (cylinder pull down) and WPD (winch pull down) versions and can be equipped with different kelly bars, reaching a max. pile depth of 69 m.
