Abstract

A movable crane arrangement includes 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 container, inside which at least part of the crane arrangement is placed in a disassembled or folded state for transport, if desired. One running platform is arranged to be implemented on the roof of the container at a selected height, and the other running platform is arranged to be implemented on the erecting platform of the crane arrangement. A method for erecting such a crane arrangement is also disclosed.

First claim

1 . 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, if desired, in a disassembled or folded state for transport, wherein one running platform is arranged to be implemented on the roof of the container at a selected height, and the other running platform is arranged to be implemented on the erection platform of the crane arrangement.

2 . The movable crane arrangement as claimed in claim 1 , wherein auxiliary erecting means are arranged that comprise erecting columns supported to the container, and lifting devices fastened to the erecting columns, and at least part of the auxiliary erecting means may be fitted into the same container, if desired.

3 . The movable crane arrangement as claimed in claim 2 , wherein the lifting devices are selected from a group that consists of at least a winch, tackle, and a chain hoist.

4 . The movable crane arrangement as claimed in claim 1 , wherein the long side of the container opens.

5 . The movable crane arrangement as claimed in claim 1 , wherein the fastening points of the erecting columns are at the opposite end corners of the container, and the erecting columns extend to a selected height above the container.

6 . 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 running platform on the roof of the container at a selected height; providing another running platform on the erection platform of the crane arrangement; and lifting with the lifting devices the main girder to the end girder and together with possible vertical legs between the main girder and end girders up by means of the auxiliary erecting means, and lowering the end girders on the running platforms.

7 . The method as claimed in claim 6 , further comprising the step of arranging the long side of the container to open.

8 . The method as claimed in claim 6 , further comprising the step of arranging at least part of the crane arrangement inside said container in a disassembled or folded state for transport, when the crane arrangement is brought to the erecting site or taken away from the erecting site.

9 . The method as claimed in claim 6 , further comprising the step of arranging at least part of the auxiliary erecting means inside said container, when the crane arrangement is brought to the erecting site or taken away from the erecting site.

10 . The method as claimed in claim 6 , further comprising the step of fastening the erecting columns to the opposite end corners of the container in such a manner that erecting columns extend to a selected height above the container.

11 . The method as claimed in claim 6 , wherein the lifting devices are selected from a group that consists of at least a winch, tackle, and a chain hoist.

12 . The method as claimed in claim 6 , wherein the main girder with its end girders and possible vertical legs between the main girder and end girders are first lifted up to be parallel to the container, and next the main girder is turned so that the end girder on the container side enters an approximately 90° angle in relation to the main girder.

13 . The method as claimed in claim 12 , wherein the main girder is turned when the end girder on the container side is already on its running platform.

14 . The method as claimed in claim 12 , wherein the end girder on the container side is lowered on its running platform only after the main girder has been turned.

15 . The method as claimed in claim 6 , wherein one running platform is arranged right on top of the roof of the container.

16 . The method as claimed in claim 6 , wherein one running platform is arranged on a support structure on the roof of the container, and said auxiliary erecting means of the crane arrangement are used in erecting the support structure.

17 . The method as claimed in claim 7 , further comprising the step of arranging at least part of the crane arrangement inside said container in a disassembled or folded state for transport, when the crane arrangement is brought to the erecting site or taken away from the erecting site.
