Abstract
The present invention relates to a crane control apparatus for a crane where a load is suspended on a crane cable from a cable suspension point of the crane, comprising an observer for estimating at least the position and/or velocity of the load from at least one sensor input of a first sensor by using a physical model of the load suspended on the crane cable, whereby the physical model of the observer uses the load position and/or the load velocity as a state variable.
