Method for monitoring safety of crane, involves monitoring multiple safety criteria during crane operation, and computing and monitoring permissible specific threshold value for each criterion during crane operation based on parameter

摘要

The method involves monitoring multiple safety criteria e.g. component strength, component load and crane stability, during crane operation. A permissible specific threshold value i.e. permissible specific load, is computed and monitored for each safety criterion during the crane operation based on a parameter e.g. crane configuration and/or crane movement. The criteria are divided into linear dependant and linear independent computation types for computation of a permissible total load that is computed from the specific threshold value of the criteria. Independent claims are also included for the following: (1) a crane (2) a crane control device (3) a data carrier comprising a set of instructions for executing a method for monitoring safety of a crane.
