IN A bid to optimise the use of its scaffolding systems, German scaffolding specialist Wilhelm Layher has developed the new Allround bridging system, which extends the areas of applications for its Allround structures while enhancing their efficiency, according to a spokesman for the company.

“The new Allround bridging system not only permits an enormous increase in the load-bearing capacity of Allround structures, but also allows Allround equipment to be used for even more applications,” he says.

The spokesman elaborates: “For bridging wide spans or for supporting heavy loads, project-related and hence expensive one-off structures are often needed. With the innovative Allround bridging system, scaffolding erectors can now offer this capability to their customers, with only a few additional parts. The advantages include quick and easy assembly, flexible and repeated use, and high load-bearing capacity.”

The new development is a modular truss system that is fully compatible with Allround equipment. The system expansion comprises only a few additional parts that further increase the load-bearing capacity of the system. Simple pin connections ensure quick and easy assembly of the individual components, including a truss post, a truss ledger and a length-adjustable diagonal rod.

“This means that supports for heavy loads or wide-span pedestrian bridges of up to around 30 m freely spanned can now be constructed,” he continues. “Cladding using our Protect System and roof covering for the bridges are also possible. Thanks to the modular design, the bridging system can be individually adapted to a variety of situations and is hence extremely economical, unlike one-off products.”

The Protect System is designed for use with both Allround and SpeedyScaf equipment from Layher. The system provides a proven means of containing noise and dust – with added aesthetic benefits, according to the spokesman.
Featuring a lightweight aluminium frame that is in-filled with either sheet steel or plastic webbing to create a complete ‘skin’ around a structure, the system affords both internal and external protection. Additionally, sound absorbent matting can be fitted to minimise noise pollution.

The new Allround bridging system was developed as part of Layher’s constant efforts to develop new applications for its scaffolding systems.

The possible uses of the new product are wide-ranging, for example, to build wide-span temporary roofs or bridging structures. Another use is for supporting scaffolding, podiums or roof structures. To do so, the bridging system is connected to the structures above it using the integrated Allround standards. This apart, it is even possible to link up downward-suspended scaffolding or several lattice beams next to one another for a further increase in the load-bearing capacity, the spokesman says.

When building a pedestrian bridge, it is also possible to pre-assemble it on the ground and then place it with a crane, which is a particular advantage when roads have to be bridged, he points out.

Available in the dimensions 2.07 m and 2.57 m, the Allround bridging system is, thanks to its high load-bearing capacity, an ideal supplement to Allround equipment and opens up new fields of business to Layher customers.

“Layher Allround scaffolding has become established on the market as a synonym for modular scaffolding,” says the spokesman. “At the heart of the original Layher Allround scaffolding system is the Allround connector. Its design features a ‘rosette’ welded onto the upright component, which can safely and securely accommodate eight individual connections.

“Developed for one-man assembly, irrespective of height, scaffolds can then be constructed in all three dimensions from each rosette. The design allows ledgers or transoms to be connected at right angles with additional components then fixed at variable angles with each stage automatically centred and correctly located for safe assembly.

“With its superior technology, the Allround connector has superseded conventional scaffolding connection techniques.”
The original offers a diverse variety of uses: at construction sites, in industry, chemical plants, power stations, shipyards and for events. As scaffolding for working, protection, facades or for support, as internal or birdcage scaffolding or rolling towers, Allround equipment offers flexible options for all requirements, even with very difficult layouts and architectural styles and with heightened safety requirements.

Up to eight connections can be made in the Allround connector on one level and at various angles. The four small punched-out openings in the rosette automatically centre the ledger at right angles –  the four large openings allow the angle of alignment to be selected.

The basic components are based on the unique connection technology which provides verified high load-bearing capacity and reduces the required material to a minimum, according to the spokesman.

A few basic components form the basis for the huge variety of uses. These include decks (planks), which are made of hot-dip galvanised steel, aluminium or an aluminium frame with plywood board.

Wilhelm Layher is considered to be the largest manufacturer of system scaffolding in Europe and has been producing exclusively in Germany since it was founded in 1945. The company now employs more than 1,100 people internationally.
