Abstract
The invention relates to a method for monitoring the crane safety of a crane with a variable support base and with a monitoring unit, wherein several safety criteria are monitored during crane operation, in that, for each criterion which is dependent on at least one parameter relating to the crane configuration and/or crane movement during crane operation, an admissible specific limit value is calculated during crane operation, and monitored for compliance. In addition, the invention relates to a method for operating a crane with a monitoring unit which calculates an admissible bearing load dependent on one or more modifiable parameters, during the operation of the crane, and a sensor system which detects the current modifiable parameters during crane operation, and makes them available to the monitoring unit, wherein one or more sensor values are modified before the calculation of the admissible bearing load, in order to determine the admissible bearing load for one or more future parameters.
