Abstract

A surrounding frame can be attached to a crane tower of a tower slewing crane and can connect the tower slewing crane to an object, for example a building, having a flexurally stiff connection element and a latching element. The connection element is provided in the form of an element that horizontally supports the crane tower in the anchorage plane at two outer sides. A method of assembling the surrounding frame and a use of a surrounding frame for connecting a tower slewing crane to an object are also described.

First claim

The invention claimed is:

1. A surrounding frame that can be attached to a crane tower of a tower slewing crane and that can connect the tower slewing crane to an object, comprising:
a flexurally stiff connection element,
a latching element, and
at least one auxiliary suspension section, to which an auxiliary suspension is attachable, which connects the surrounding frame to the tower slewing crane,
wherein the connection element horizontally supports the crane tower in an anchorage plane at two outer sides.

2. The surrounding frame in accordance with claim 1 , wherein the auxiliary suspension comprises a rope.

3. The surrounding frame in accordance with claim 1 , further comprising at least one support section at which the surrounding frame can be contacted by at least one support console in a horizontal position and which can be fixed by the support console.

4. The surrounding frame in accordance with claim 1 , wherein the latching element comprises two latching braces, connected to one another in an articulated manner, that are connected to the connection element in an articulated manner.

5. The surrounding frame in accordance with claim 4 , further comprising at least one fastening section provided at a bracket section and at least one anchorage brace that is fastenable to said at least one fastening section, with an anchorage brace being connectable to the object.

6. The surrounding frame in accordance with claim 5 , wherein the at least one fastening section comprises at least one opening as anchorage geometry.

7. The surrounding frame in accordance with claim 1 , further comprising at least one support section provided at the connection element and at the latching element that supports the surrounding frame against the tower slewing crane.
