Layher the name of multinational scaffolding company produces high-quality scaffolding systems in Germany. Layher has worldwide presence with more than 40 sales subsidiaries. The products are being used by industries like construction, chemical plants, power plants, at shipyards and offshore. Now days for demanding and complex scaffolding applications – i.e. wherever conventional scaffolding technology falls short of optimal thus cost effective use, Layher Allround Scaffolding convincingly comes in with an unmatched range of advantages: unbeatably fast assembly, persuasive economic arguments and an extensive range of series-produced accessories.

The proven combination of positive and non-positive connections in a rapid and bolt-free system technology with AutoLock function facilitates connections that are automatically right-angled, obtuse-angled and acute-angled – and ensures built-in safety at the same time. Layher Allround Scaffolding has now become synonymous with modular scaffolding on the market.

Since its launch in 1974, this original system has been undergoing continuous development and offers an impressive variety of use: on any construction site, in industry, chemical plants, power stations, shipyards and for events. As scaffolding for working, protection, façade work or support, as internal or birdcage scaffolding, or as rolling towers.

Even with very difficult layouts and architecture styles and with heightened safety requirements, Allround Scaffolding is the faster, safer and more economical solution.

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.

Application of Layher Allround for Sheet Replacement of ACES Tower Lift (A Train) at 92 mtr Height
The multiple structured with different sizes operated by chemical and fertiliser 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 with full safety 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 92 metres 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.

Due to restriction of open space possibilities of access Aluminium deck with integrated ladder is only possibilities. Internal accesses can be built into the scaffolding with the access decks. These decks conform to the requirements of DIN EN 12811 and are available with a separate or an integrated access ladder for internal access.
The stability of a structure shall be checked both with and without the wind loads, as there may be reversal of the forces under wind besides a reduced factor of safety considered with the wind loads as per IS 875 (Part 3). Assembly, alteration and dismantling of the Layher Allround Scaffolding involve a risk of falls. Perform scaffolding assembly work in such a way that the risk of falls is avoided as far as possible and that the residual risk is minimised. Assembly situations where there is a risk of falls are indicated in these instructions with the following symbol inside the assembly pictures.

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 to the topmost existing structure. 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 and applicable accessories.

Construction of scaffolding to make approach for all required location was major challenge during the work due to unsymmetrical structure, but it is easy when will consider Allround Scaffolding Systems.

Layher new Lightweight scaffolding is result of a major, multi-year R&D project with as clearly defined objective: to make scaffolding easier, safe and above all more cost effective for customer.
