Abstract
A drilling unit, with a carrier vehicle, a mast rotatably mounted on the carrier vehicle about a pivot axis, which mast can be pivoted between an erect operating position and an inclined transport position, and at least one erection cylinder for pivoting the mast between the operating position and the transport position. For pivoting the mast in addition to the at least one erection cylinder an erection cable is provided which is guided via a cable deflection pulley arranged on the mast, on the carrier vehicle or on a carriage which can be moved along the mast, and in that in order to apply a pulling force to the erection cable via the cable deflection pulley an erection force can be transferred to the mast in the direction of its operating position. The invention further relates to a method for erecting a mast of a construction work unit.
