1. A mobile crane comprising:
- means for identifying a location of the crane by wireless reception of location data or by determination of location data;
means for wirelessly transmitting the location data to a receiver in communication with or connectable to the wireless reception or determination of the location data;
means for storing the location data;
means for testing a connection quality and existence of a transmission path for the wireless transmission of location data from the crane to the receiver; and
a controller configured to;
initiate storage of the location data when the connection quality is below a limit value or when the connection does not exist, andinitiate transmission of the stored location data when the connection quality exceeds a limit value or when there is a connection;
wherein if a wireless signal is not transmitted or not transmitted in a specific period of time by the wirelessly transmitting means, the operation of the crane is restricted or stopped.
