Abstract: A drilling device, comprising a chassis, two undercarriage units which are arranged laterally on the chassis and supported in a pivotable manner, two oscillating cylinders for pivoting the undercarriage units relative to the chassis, with an oscillating cylinder being assigned to each undercarriage unit, and hydraulic lines which are arranged on the oscillating cylinders for actuation of the oscillating cylinders, wherein the hydraulic lines of the two oscillating cylinders are connected to one another in order to pivot the undercarriage units in opposite directions. A safety device to be provided for line breakage safety on at least one hydraulic line for each oscillating cylinder, with each safety device having at least one remote-controlled stop valve for blocking the respective hydraulic line in the case of line breakage, and in that a remote-control device is provided for simultaneously opening the stop valves during normal operation.
