Abstract

Die Erfindung betrifft ein Verfahren zur Ermittlung der zulässigen Traglast eines Krans, bei dem die Traglast in Abhängigkeit von wenigstens einem ersten und zweiten Parameter bestimmt wird und das einen ersten Schritt umfaßt, bei dem die Traglast für den Wert des ersten Parameters bei unterschiedlichen Werten des zweiten Parameters durch Berechnung oder durch Interpolation oder Extrapolation auf der Grundlage bekannter Werte der Traglast bei bestimmten Werten des ersten Parameters bestimmt wird, und das einen zweiten Schritt umfaßt, bei dem die Traglast für den zweiten Parameter auf der Grundlage der in dem ersten Schritt für unterschiedliche Werte des zweiten Parameters ermittelten Werte der Traglast durch Berechnung oder durch Interpolation oder Extrapolation durchgeführt wird.The invention relates to a method for determining the permissible load of a crane, wherein the load is determined in dependence on at least a first and second parameters and comprising a first step, wherein the load for the value of the first parameter at different values of the second Parameter is determined by calculation or by interpolation or extrapolation on the basis of known values of the load at certain values of the first parameter, and comprising a second step, wherein the load for the second parameter based on the in the first step for different values of the second parameter is determined by calculation or by interpolation or extrapolation.
