Layher Scaffolding Systems Pvt Ltd

The Layher (the name of German Company) has been producing high-quality scaffolding systems in Germany for more than 60 years. Layher is present worldwide with more than 30 sales subsidiaries. The products are used for building and construction, in all kinds of industries like chemical plants or power plants, at shipyards and offshore. Due to innovative products, superior technical solutions and Layher’s absolute customer-orientated service package, Layher has become the standard in scaffolding systems worldwide.

More Possibilities. Layher Products And Services

Customers can see for themselves the capabilities of Layher Allround Scaffolding Systems every day with its corporate philosophy of “More possibilities. The Scaffolding System.” Layher presents product characteristics and services that help customers achieve long-term success and increase their companies’ profitability. Continually optimizing all its scaffolding systems and making their application more effective gives Layher’s customers a crucial advantage in their practical operations.

The Layher Allround Scaffolding has been established as a synonym for modular scaffolds on the market. With its unique, bolt-less connection technique, the patented Allround joint replaced the conventional scaffold technique. The Allround Scaffolding offers unsurpassed versatility in use: on construction sites, in industry, in the chemical industry, in power plants, in the aircraft sector and shipyards, in the event sector, in theatres and arenas, Allround Scaffolding does full justice to its reputation as an “Allrounder”.

Requirements for working, protection, a facade, or support scaffolding with the most challenging structures and architecture, including the engineering construction sector, were supremely fulfilled with Allround Scaffolding. This system’s focus is the Allround joint permitting up to 8 connections in one plane with automatic right angling and flexible angle selection with self-locking wedge head couplers.

Application In Construction Of Power Station [NDCT Ring Beam]

All thermal power stations need cooling towers, and it can be natural draft cooling towers or inductions draft cooling tower. A cooling tower houses a large network of RCC columns and beams to create the support for the cooling fills. The cooling tower construction is challenging due to heavy load coming on inclined columns and ring beams. The selection of support systems (scaffolding or temporary structure) to construct NDCT ring beam and inclined circular columns is very important to complete the project. Layher Allround Scaffolding systems provide a unique, bolt-less connection technique. The patented Allround joint has replaced the conventional scaffold technique, especially in the construction of the cooling tower. Allround Scaffolding can accommodate all types of high loads and is ideal for all kinds of support scaffolding. It has an efficient solution to deal with all challenges, regardless of whether they involve falsework at great height or round inner scaffolding.

A ring beam over the inclined columns constitutes the first lift of the cooling tower shell. It needs to be built in a modular scaffolding system to construct a ring beam and inclined column. This lift acts as a starter for further laying lifts of the cooling tower shell by using very special support systems that are best possible by using Layher Allround Scaffolding Systems. For the construction of the first lift, Allround Scaffolding is used to support the inclined shell and NDCT (natural draft cooling tower) ring beam. Layher Allround Scaffolding gives outstanding performance against true curvature of the shell support (replacing traditional support systems) and effectively transferring stresses.

Layher Allround Scaffolding makes an ideal propping system, especially during pouring of concrete and to resist concrete pressure, friction hoists to lift the buckets full of concrete to the working platform, concrete mixers, and needle vibrators, to optical instruments to check the alignment and curvature of the ring beam buckets and trolleys for concrete transportation.

Evenly distributed and radially arranged supporting towers made of Allround equipment provide the crucial bracing needed by the circular scaffolding. Thanks to Allround equipment, these supporting structures are ideally matched to the circular scaffolding requiring the bracing effect, and thus absorb a substantial proportion of the horizontal load components from the Allround Scaffold structure.

Layher Allround has a suitable solution for all access need on the construction site. Access stairway towers for a broad spectrum of applications and requirements are created at the site for hoisting of concrete buckets, passenger hoist and to accommodate Modular Stairway, accesses that always fit and that match the system can be constructed (replacement of huge quantities of scaffolding pipes and clamps) are possible by using Allround Scaffold Systems.

Permissible load can be increased considerably by using Layher Special Reinforced base plate, Head Jack (U-Head), and diagonals suitable for veavy load and horizontal.

The structures stand out as living testimonies to man’s victory over nature. These are the structures conceived and built by minds in constant search of new methods, ideas, applications, and solutions.
