Vertical excavator drilling rigs of the WPK C series are used to make holes vertically. The drilling rig is mounted to the excavator’s arm with a quick coupler or a pin. The technology of using a through head allows the production of CFA piles by connecting the pump directly to the drilling rig. The machine is designed for excavators weighing from 29 tons.
