Crane e.g. mobile crane, has monitoring and simulation unit monitoring and/or simulating state of crane, and presenting state history of crane at any time during movement of crane and/or intersect of crane

摘要

The crane has a monitoring and simulation unit (10) monitoring and/or simulating a state of the crane, and presenting a state history i.e. limit load curve, of the crane at any time during movement of the crane and/or intersect of the crane. The simulation unit comprises an input unit (12) and an output unit (14). The simulation unit a computing unit provided for evaluating parameter describing a current state of the crane and simulating and/or computing the state history of the crane.
