The present disclosure relates to a method for determining the admissible load capacity of a crane, in which the load capacity is determined in dependence on at least one first and one second parameter and which comprises a first step, in which the load capacity for the value of the first parameter with different values of the second parameter is determined by calculation or by interpolation or extrapolation on the basis of known values of the load capacity with specific values of the first parameter, and which comprises a second step, in which the determination of the load capacity for the second parameter is performed on the basis of the values of the load capacity determined in the first step for different values of the second parameter by calculation or by interpolation or extrapolation.

Method for determining the load capacity of cranes

The present invention relates to an angle-related method of monitoring crane safety during the setup procedure of a crane, wherein the crane has a sensor system and a crane control and the crane control receives one or more measured values from the sensor system during the setup procedure and compares the measured value or values received with at least one corresponding limit value and triggers a measure on an exceeding and/or falling below of the limit value or values.

Method of monitoring crane safety during the setup procedure, as well as crane and crane control

The present disclosure relates to a method of operating a crane whose safe working load depends on one or more changeable parameters, with the change of at least one of the parameters being made such that the speed of the parameter change is reduced continuously or step-wise before a parameter value is reached at which the safe working load corresponds to the actual working load.
