The invention relates to a method for calibrating a first movable crane part of a crane. In a first step a first crane part is positioned above a calibration point at a first predetermined co-ordinate in a reference system. Subsequently a first distance is measured 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. Then an orientation of the first transmitter/receiver element of the first distance measuring device in the reference system is ascertained in accordance with the first predetermined co-ordinate, the measured first distance and a first item of information concerning the surroundings. Next a transformation is performed in the reference system in accordance with the ascertained orientation of the first transmitter/receiver element of the first distance measuring device for a transformation of a distance measured during operation of the crane by means of the first and second transmitter/receiver elements of the first distance measuring device measured for determination of 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. This results in simple installation. Moreover only one calibration point has to be approached in order to calibrate the crane. The invention further relates to a method for operating a crane and to a crane.
