<p>The core sample trailer chassis (3) is towed by a tractor (2) and has an enclosed driver's seat (6). On each side of the trailer four hydraulically driven core sampling consoles (11) are suspended by arms (51, 52) and operated by hydraulic pistons (8) which move them from a parked position to a semi-elliptical operating mode. Eight core samples are taken simultaneously, then automatically removed, mixed and bagged for analysis</p> |
