Method for monitoring crane safety and crane

摘要

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.

1. A method for monitoring the crane safety of a crane with a variable support base and with a monitoring unit, comprising the steps of
monitoring several modifiable safety criteria during crane operation, calculating an admissible specific limit value for each criterion which is dependent on at least one modifiable parameter relating to at least one of the crane configuration or crane movement during crane operation, during crane operation is during run-time of the crane, monitoring the thus-calculated specific limit for compliance during crane operation, stopping the crane when the admissible specific limit is reached or exceeded, and calculating a new admissible bearing load based on simulated sensor values for future crane movement and changes to the at least one modifiable parameter, for moving the crane back within the admissible specific limit value during crane operation.
