Layher Allround: The Ideal Bridging System
Layher Scaffolding Systems Pvt. Ltd.
The Allround bridging systems is the ideal complements to Layher Allround equipment with just few additional components, the load-bearing capacity of the proven Allround systems can be increased enough to create special structures like, wide- span footbridges or support structure for heavy loads.
The Allround Bridging system is a modular truss system that can be adapted to the respective application. The posts of the Allround Bridging Systems have wedge heads welded to the side, to which standards of the Allround equipment can be fastened. As a result, the Allround Bridging Systems can be combined with Allround equipment, offering a wide range of possible uses. A complete integration into an Allround Scaffolding structure (e.g. to transfer high loads or for bridging of wide spans) is also possible. The individual components of the Layher Allround Bridging System are connected in a time-saving way using bolts of diameter 30 mm. The connection to the Allround equipment is made using the proven Allround wedge head connection.
Innovative supplementary component: even unsupported bridging structures with a span of up to 30 meters can be completed, or high loads can be supported due to the modular All-round bridging system from Layher.
A standard Layher bridge structure mainly comprises two loads transferring Allround Bridging Systems which are arranged parallel to one another at a defined distance, depending on the required bridge width. A stable bridge supporting structure is obtained with an internal Allround scaffolding structure fastened between the two Allround Bridging Systems, The stiffening in the transverse direction and hence the stabilization of the Allround Bridging Systems is achieved with horizontally arranged bracing in the Allround structure. The bridge decking and the guard rails are fastened to the internal Allround scaffolding structure. The entire bridge structure – both bridging units in combination with internal Allround Scaffolding – is finally supported at the bridge ends. The support can for example be on individual Layher heavy-duty supports integrated into a separate stairway access. In some cases, it is also possible to support the end posts of the bridge directly on existing foundations, beams or walls.
With the new development "Allround bridging system," Layher offers the optimal solution for the construction of a more than hundred metres long pedestrian crossing with free spanned bridge elements of 31 metres.

Layher Allround Bridging System as temporary pedestrian bridge at Seedorf
As a replacement for the closed bridge, the Federal Office for Streets in Bern (ASTRA) ordered the construction of a temporary pedestrian crossing which was to cross the motorway and the river parallel to the existing bridge. Tasks of this nature generally require project-oriented and therefore expensive special constructions. With the innovation from Layher, scaffolders can now offer this service much more efficiently with only a few additional components to the Allround system. After a successful appearance in Davos at the World Economic Forum, the use of the Allround bridging system for this project with supporting spans of up to 31 metres was also the optimal solution.
