Definitions
- Crane in particular overhead crane or gantry crane, with at least one crane girder
- the invention relates to a crane, in particular bridge crane or gantry crane, with at least one horizontally extending and designed as truss with multiple struts crane carrier on which a trolley with a hoist is movable, wherein at least some of the struts are formed flat and the sheet-like struts one each have planar main surface which extends transversely to a longitudinal direction of the crane girder.
- a crane is known from German patent application DE 10 2012 102 808 A1.
- the struts are arranged in pairs saddle-roof-like and between the struts of each strut pair a vertically extending post is provided.
- the struts have stiffening folded longitudinal sides. Due to the folds of the longitudinal sides of auxiliary surfaces are formed between lower first and upper second recesses, which adjoin the main surfaces as so-called Beulsteifen, compared to the major surfaces are bent at approximately right angles and transverse to the longitudinal direction of the crane girder.
- the struts are generally considered to be those supporting elements of a truss structure which have an oblique
- the struts of a truss structure differ from the supporting elements, which run exclusively vertically and are referred to as posts.
- the sheet-like struts or surface struts preferably take forces in the direction of their longitudinal axis and thus in the plane of their flat plane
- Surface struts differ, for example, from bars or rod-shaped posts and struts in that their thickness dimensions are substantially smaller than the length and width dimensions determining the areal extent of the pane. Accordingly, sheet-like struts are also referred to as surface struts or disc struts.

- the main surface is constricted transversely to the longitudinal axis, whereby the struts in each of these areas a kind
- the longitudinal sides are formed without kinking over their entire length. As a result, the production cost can be further reduced.
- Truss structures all individually customized rod-shaped struts or sheet-like struts with complex to be produced adjacent surfaces are replaced by uniform design inventive sheet-like struts. This leads to a significant manufacturing advantage, since each sheet-like strut is made of a laser-cut sheet steel without further elaborate manufacturing steps. The structure of the struts is thus only by appropriate

- preferably circular recesses is the
- Main surface constricted transversely to the longitudinal axis, whereby the struts in each of these areas form a kind of membrane joint and cause an optimized flow of force through the strut.
