The safe lifting load of any crane that has been properly installed and maintained is determined by the engineering spec. a Crane is designed from the beginning to lift a load by transferring that load through the supporting structure to the ground or/ to the floating vessels structure in the case of a floating crane. All cranes are required to be marked for max capacity, and if it is not marked, get the serial number and contact the manufacture. If no information is available a certified PE must calculate the load limit.
