Layher continues to lead the scaffolding sector with its modular Allround system, offering fast, safe, and highly adaptable solutions for complex projects in construction, chemical plants, and shipyards. With over 45 global subsidiaries, Layher is a trusted partner for industrial needs worldwide.

Layher, the name of the German scaffolding company, produces high-quality scaffolding systems in Germany. Layher has a worldwide presence with more than 45 sales subsidiaries. Industries like construction, chemical plants, power plants, shipyards, and offshore are using the products. Nowadays, 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.

Layher’s present product characteristics and services help customers achieve long-term success and increase their companies’ profitability. The Layher Allround Scaffolding has been established as a synonym for modular scaffolds on the market. It offers unsurpassed versatility for construction sites, the chemical industry, power plants, aircraft, shipyards, the 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 ensure the other end of the ledger. A hammer blow to the wedge transforms the loose connection into a 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. This allows the tower to be assembled on the ground and placed by crane.

Application of Layher Allround Scaffold for maintenance of column in refinery
A distillation column is a critical equipment in refining crude oil. It acts like a still, separating the product into its different chemical components based on differences in volatility. Oil refineries use two main types of distillation columns.

The multiple structures with different sizes operated by the refinery are currently being refurbished, and corrosion prevention experts must treat the entire structure occasionally. A modular scaffolding system ensures safe access to all locations of the main building. By using Allround Scaffold, it is only possible to complete maintenance on time as per requirement.

The advantage lies in the speed with which the system can automatically obtain the right angle variable angles, which 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 the conditions on-site dictate. The Scaffolder can easily, thanks to the eight possible connections in every connector, make adaptions quickly and optimally for almost any application.

These advantages 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 being 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, logical assembly sequence and integral safety. Hot-dip galvanization and certified quality ensure that all-around scaffolding’s top-quality products are extremely long-lived.

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

Conventional anchoring to the tank was not possible. The scaffold erectors were only able to make connections to the all-around 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-around steel cables. A Layher landing-type stairway tower allowed convenient access to the scaffold at various levels.

The scaffold’s lift 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 at the highest point of the building using Allround standards.

The application of a lattice girder was considered in the design to construct a cantilever projection on top to provide proper access. Construction of Scaffolding to approach all required locations was a major challenge during the shutdown, but it is easy when considering all-around scaffolding Systems.

The stair tower is either integrated into the scaffolding or as a free-standing access structure anchored on the building. It is helpful for the transportation of materials and manpower from ground level to the top of the structure.

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