Abstract (en)

[origin: EP2674384A1] The method involves calculating one or more changeable parameters depending admissible load during the crane operation. The current changeable parameters are detected by a sensor (10) during the crane operation. One or more sensor values (11-13) are modified based on the current changeable parameters before calculation of the admissible load, to intend the permissible load for one or more future parameters. Independent claims are included for the following: (1) crane; (2) control unit; and (3) data storage medium storing program for implementation of method for driving crane.
