Shearing screw

A system is provided for identifying an operator and managing access rights in connection with a crane. The crane includes a control system and a controller positioned at a distance from it. The control system maintains a plurality of operator-specific parameters that define operator rights. An identifier reader is placed in connection with the controller for reading the operator's identifier by using a first connection. A second connection is set up between the identifier reader and the control system to send the operator's identifier, or information derived from it, to the control system. The control system compares the operations requested through the controller with the operator-specific parameters, which define operator rights, and allows the operation of the crane only within the scope of rights associated with the operator's identifier.
