Crane drilling rig CH 450

rotary

The CH 450 is the first Comacchio drilling rig for large diameter drilling. The CH 450 is the ideal solution for job sites that require fast operating times. The machine is totally self-erecting, and can be transported in one piece with the kelly mounted. Once in place, the machine is easily downloaded from the truck and set up without the need for crane service. Lifting of the mast takes a few minutes and can be performed in complete safety. The CH 450 is designed to cover a wide range of processes that include bored piles, continuous flight auger (CFA piles), micropiles, displacement piles and soil mixing. The machine can be supplied in the CPD (cylinder pulldown) and WPD (winch pulldown) versions and can be equipped with kelly bars with a maximum length of 13.0 to 13.5 m (CPD-WPD) and with different outer diameters, including HD (heavy duty) and XHD (extra heavy duty) bars.
