ABSTRACT:
A mobile crane includes an undercarriage or lower crane carrying chassis, an upper load lifting and carrying chassis pivotally mounted on the lower chassis, a cab located on the upper chassis for operating the crane, a base section that can be swivelled about a horizontal axis, and a separate boom attachable to a free or operating end of the base section. The base section has a novel, essentially one-piece construction that is designed in such a manner that with it alone especially crane operations can be performed. Attachment devices for attaching the separate boom are provided on the free end of the base section. The base section extends virtually over the entire length of the lower chassis. Thus, maximum loads and maximum lifts can be obtained with universal and versatile application.
