A hydraulically controlled device, powered by the output lines of the excavator or the aggregate. It performs drilling with diameters from 159mm to 355mm up to ~ 30m in length depending on ground conditions. It is perfect for drilling for various types of installations, including: water supply, sanitary, heating, as well as electric networks. Drilling may only be performed with augers or augers in steel pipes. The device uses a drilling system, the so-called “”Boxer””, based on a set of two additional actuators, allowing slight movements of the augers themselves along the axis of the casing pipe. This system is used when encountering an obstacle or when drilling in very hard ground. In addition, the drilling rig has the option of a quick return stroke of the actuators, the purpose of which is faster installation of the next pipe. At the customer’s request, we make beds of the following lengths: 1m; 1.5m; 3m. Guarantee period: 12 months.
