1. A crane, in particular a crawler crane or mobile crane having at least one monitoring and simulation means (10) by which a state of the crane can be both monitored and simulated, wherein
the monitoring and simulation means (10) has least one input means (12) and at least one output means (14), said monitoring, means (10) monitoring at least one of actual state and actual state development of the crane and actual state and actual state development of a boom of the crane, wherein the actual state and the actual state development of the crane includes movement of the crane or the boom of the crane simulation means (10) representing and simulating at least one of a possible state and possible state development of the crane during crane operation, the simulating including a displayed virtual movement of at least a portion of the crane, and the actual and simulated states are both displayed by at least one monitor (10) forming part of the monitoring and simulation means (10) during the crane operation, wherein during crane operation the crane moves in response to a demand of a crane operator and the monitor displays the actual state of the crane, wherein the actual state of the crane switches to the simulated state of the crane after the crane moves and on demand by the crane operator, and when the switching to the simulated state occurs on demand by the crane operator the monitor displays a current state of the crane from the monitoring means, wherein the simulated state includes the displayed virtual movement of the at least the portion of the crane by the crane operator. |
