A movable crane arrangement comprising:
- a main girder for a trolley;
- end girders with running wheels to be supported on both ends of the main girder;
- running platforms for the running wheels of the end girders;
- and
- one elongated transport container, inside which at least part of the crane arrangement can be placed, in a disassembled or folded state for transport,
- wherein one of said running platforms is arranged to be implemented on a roof of the container at a selected height, and another one of said running platforms is arranged to be implemented on an erection platform of the crane arrangement, and
- wherein auxiliary erecting means comprise erecting columns supported to the container, and lifting devices fastened to the erecting columns, and at least part of the auxiliary erecting are fitted into the same container.
A method for erecting a movable crane arrangement that comprises a main girder for a trolley;
- end girders with running wheels to be supported on both ends of the main girder;
- and running platforms for the running wheels of the end girders, said method comprising the steps of:
- providing one elongated container;
- providing auxiliary erecting means for the crane arrangement that comprise erecting columns and lifting devices, wherein the erecting columns are supported and fastened to the container and the lifting devices are fastened to the erecting columns;
- providing one of said running platforms on a roof of the container at a selected height;
- providing another of said running platforms on an erection platform of the crane arrangement;
- and
- lifting with the lifting devices the main girder and the end girder up by means of the auxiliary erecting means, and lowering the end girders on the running platforms.
