A method for calibrating a first movable part of a crane. Position a first crane part above a calibration point at a first predetermined co-ordinate in a reference system. Measure a first distance between a first transmitter/receiver element of a first distance measuring device mounted on the first movable crane part and a second transmitter/receiver element of the first distance measuring device disposed in a stationary manner in the reference system. Measure an orientation of the first transmitter/receiver element in accordance with the first predetermined co-ordinate, the measured first distance and a first item of information concerning the surroundings. Perform a transformation in the reference system in accordance with the ascertained orientation of the first transmitter/receiver element for transforming distance measured during operating of the crane by means of the first and second transmitter/receiver elements to determine a position of the first movable crane part. Because the method makes use of information concerning the surroundings, an installation position of the first transmitter/receiver element on the first movable crane part does not have to be known precisely. Moreover only one calibration point has to be approached in order to calibrate the crane.
