The WSM-80 “”mini geolog A”” drilling rig is used for drilling vertical holes with the use of “”dry”” screw augers in order to collect soil samples. It is a mobile machine equipped with its own free-running wheel drive, powered by a drilling rig, which is used to drive the drilling rig at short distances to the drilling site in difficult terrain – where access by car is difficult. The drive has two gears: slow gear – for precise setting of the machine over the drilled hole, and fast gear – for driving. The drilling rig is equipped with screw anchors screwed into the ground to a depth of 0.8 m to ensure stabilization.
