For more than 70 years now, Layher (the Name of German Company) has been the undisputed pioneer for top-class scaffolding systems “made in Germany”. With its ideas, this future-looking and highly innovative family-owned company has continually been giving vital new impulses to scaffolding construction and profoundly influenced developments. But Layher not only means high-quality scaffolding, protective and event systems, rolling towers and ladders: it is also a dependable partner of customers from scaffolding, crafts, construction, industry and the events business when it comes to outstanding services. Every day, more than 1,500 highly qualified and motivated employees are creating “more possibilities” – at the highly automated headquarters in Gueglingen-Eibensbach or at the sales subsidiaries in more than 35 countries all over the world.

More Possibilities – Layher Products and Services
Layher’s present product characteristics and services help customers achieve long-term success and increase the profitability of their companies. The Layher Allround Scaffolding has been established as a synonym for modular scaffolds on the market. The Allround Scaffolding offers unsurpassed versatility to be used in construction sites, chemical industry, power plants, aircraft, shipyards, event sector, theatres and arenas.

Allround scaffolding uses a simple, unique and bolt free connection technology. Sliding the wedge head over the rosette and inserting the wedge into the opening immediately secures the component. There is still sufficient play to secure the other end of the ledger. A hammer blow to the wedge transforms the loose connection into a superbly strong structurally rigid one. The face of the wedge head is now precisely positioned against the standard. Connections in quick to assemble and spanner less scaffolding systems make a unique combination: providing structural strength immediately on assembly and subsequent ultimate force transmission while offering a choice of automatically right – angled or splayed connections with universal safety right from the start.

To transfer pulling force, every frame is secured by locking pins or bolts to each other. In this way the tower can be assembled on the ground and placed by crane.

The Layher Allround System in steel with its highly functional components permits complex and very difficult scaffolding structures to be built.

The considerably lighter Allround scaffolding made of Aluminium combines outstanding system technology with a substantial reduction in weight.

Layher systems are versatile for a wide variety of applications, and can be combined with one another.

Application of Layher Allround Scaffold for maintenance of Refinery
The Multiple Structured with different sizes operated by Refinery is currently being refurbished, and corrosion prevention experts have to treat the entire Structure time to time. Safe access to all location of main building is assured with the use of a modular scaffolding system. By using Allround Scaffold is only possibility to complete maintenance on time as per requirement.

The advantage lies in the speed with which not only the right angle can be automatically obtained with the system, but also variable angles can be achieved if required. This is done by fitting the ledgers in rosettes each with four holes at right angles, with four further larger holes (usually used for diagonal braces) being used to facilitate variable angles. This means that the erectors can also make connections at any angle as dictated by the conditions on site. The Scaffolder can easily, thanks to the eight possible connections in every connector, make adaptions quickly and optimally for almost any application.

These advantages is ensure the optimum conditions for effectively enclosing the Circular and rectangular structure with safe and minimal time required to construct the scaffolding. Allround Scaffolding was easily adapted to follow the contour shape of the structure without difficult to access. The erectors didn’t need to create complex tube structures, saw off tubes all the time, repeat measuring of connections or constantly align the upright elements. The wedge head provides an all in one simple yet stable connection, coupled with a logical assembly sequence and integral safety. Hot-dip galvanisation and certified quality assure Allround scaffolding top-quality products are extremely long-lived.

Several work levels were required plus a lift going up 40 meters were required to be integrated into the scaffolding. The challenge set by this particular job was to follow as precisely as possible the double-curved surface of the tank. This was possible due to the extensive capability of parts Layher are able to offer.

Conventional anchoring to the tank was not possible. The scaffold erectors were only able to make connections to the all-round steel profile – the runner rail for the inspection ladders – at the tank’s “equator” using scaffold couplers. Above and below this anchoring level, the scaffolding was secured by all-round steel cables. A Layher landing-type stairway tower allowed convenient access to the scaffold at various levels.

The top lift of the scaffold at the top of the structure called for Layher’s expertise. Following the increasingly safe scaffolding with proper Access at all locations, Layher’s Technical Bureau designed a series of connected lattice girders to the topmost Allround standards which made them converge in tension-resistant form. The scaffolders then placed the structure on the highest point of the Building using Allround standards.

Application of lattice girder considered in design to construct cantilever projection on top to fulfil proper access. Construction of Scaffolding to make approach for all required location was major challenge during the shutdown, but it is easy when will consider Allround Scaffolding Systems.
