System for determining the load mass of a load carried by a hoist cable of a crane

摘要

Abstract The present invention relates to a system for determining the load mass of a load 5 carried by a hoist cable of a crane, said system comprising a measurement arrangement for measuring the cable load in the hoist cable and a calculation unit for determining the load mass on the basis of the cable force, wherein the calculation unit has a compensation unit which describes and at least partly compensates the effect of the indirect determining of the load mass via the cable force in a model.
