According to the US Patent & Trademark Office: “A crane installation, especially a container crane, includes at least one hoist mechanism provided with at least one motor for lifting and lowering a load suspended from the hoist mechanism. The operation of the hoist mechanism is controlled by a control unit which receives load-specific information signals from a device. The load-specific information signals are determined on the basis of load-dependent measuring signals generated by a load measuring assembly associated with the hoist mechanism.”
