Comacchio 901a

Using the GEO 900 as a base design, the GEO 901 is a midsize hydraulic drilling rig capable of performing a wide range of applications, such as water well drilling, geotechnical investigations (using either destructive and non-destructive coring techniques), environmental studies, monitoring and mining exploration (using wire-line coring). The machine is equipped with a mast using a hydraulic cylinder feed system which provides up to 30,000 daN of pull. Depending on the specific applications, the GEO 901 can be equipped with different types of rotary heads, which can be suitable both for direct circulation drilling (with or without the use of a down-the-hole hammer) and reverse mud circulation drilling. The GEO 901 is also extremely versatile due to the large number of accessories available, such as double or triple clamps, various models of winches, foam pumps, duplex and triplex pumps etc.
