The invention relates to a crane, in particular a revolving tower crane or boom crane, having a hoisting cable which extends from a crane boom and carries a load hook, wherein a sling having a load fixed thereto is rigged to the load hook, which load hangs down, spaced apart from the load hook by the sling, and having a determination device for determining the position and/or excursion of the load, and an electronic control apparatus for controlling drive devices for moving crane elements and relocating the load hook according to the detected position and/or excursion of the load, wherein the determination device has first determining means for determining a position and/or excursion of the load hook and furthermore an inertial measurement unit which is attached to the sling and/or the load and which has acceleration and rotation rate sensor means for providing acceleration and rotation rate signals and second determination means for determining and/or estimating an excursion and/or position of the load from the acceleration and rotation rate signals of the inertial measurement unit, which is attached to the sling and/or to the load, and from the signals of the indicated first determination means which characterize the position and/or excursion of the load hook.
