    More Possibilities of Layher Products and Services
    Layher's products and services help customers achieve long-term success and profitability. Layher Allround and SpeedyScaf Scaffolding offers unsurpassed versatility in construction sites, chemical industries, power plants, aircrafts, shipyards, theatres and arenas, etc.

    Layher 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.

    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 scaffolding put up around new offices/apartment complexes using SpeedyScaf equipment from Layher has been "roundly" praised.

    Application of Layher Scaffold for High-Rise building in Turkey
    Construction of Façade Scaffold about 90 metres high, was a big challenge in construction of this Residential Building that rose into the sky. During construction, the biggest challenge was posed by the recessed balconies on every second side of the building. Providing scaffolding around these drew on all the experience of the scaffolding erectors and flexibility of systems. But this problem was quickly overcome with special structures by attaching the necessary anchoring continually as scaffolding assembly progressed.

    Before starting construction of the scaffolding, one needs to confirm the surface load-bearing capacity and layout, and suitable load-distributing base. These bases must extend over both uprights. When positioning, stay within the maximum clearance from the wall, otherwise, there is risk of falling. The need to follow design is sometime difficult due to site condition, and one has to stiffen the scaffolding with vertical diagonal brace.

    By bracing the scaffolding vertically with SpeedyScaf lattice beams, even the increased wind loads could be transferred without putting unnecessary strain on the structure.

    With Layher SpeedyScaf Systems, the Scaffolder had the ideal equipment for economical provision of scaffolding around the Façade of 90 metres. Easy assembly and the use of a hoist meant that the assembly time took just five weeks. Thanks to the outstanding quality of Layher products, the lower assembly frames and the spindles can withstand enormous loads. Load bearing capacity of individual spindles (base plate) are subjected to a weight of upto 5 tons.

    Especially on irregular designs due to different sizes of corner, the Allround / Speedyscaf Scaffolding impresses with its flexibility and the safe and easy handling. With its advantages like screw-less quick and self-explanatory assembly, form-fitting and solid connection, dimensional stability and rigidity, scaffolders quickly create safe workspaces for the following assembly sections. Even in the highest altitudes and under high loads. After all, heavy stones have to be stored temporarily on the scaffold during the construction/renovation.

    Layher's extensive range of parts make even round scaffolding quick to build. To do so, the scaffolding experts chose short bay lengths to comply with the permitted wall clearances, individually positioning every bay at the appropriate angle – connected to a coupler on the inner standard. This allows even structures with widely varying radii to be enclosed with scaffolding.

    Layher has a suitable solution for all access to fulfil the need in any construction site. Access Landing type stairway towers (external access)Robust Access deck with ladder (internal access) for a broad spectrum of applications and requirements are created at the site for hoisting of concrete buckets, passenger hoist, and to accommodate safe Modular Stairway/Access. Modular, accesses that always fit and match the system, can be constructed (replacement of traditional scaffolding). Huge quantities of scaffolding pipes and clamps are possible by using Allround Scaffold Systems.

    The load classes regulate the live load and dead load (theoretical load) on scaffolding must match the type of work to be performed. All live load effects must be considered in design separately and effects must be superimposed.

    The system-based advantages of Layher Scaffolding have proven to be more economical in all fields of scaffolding use (industrial construction, power station, shipbuilding, facade work, construction sites, stair tower, suspended scaffolding structures, aircraft maintenance, sub structure for podiums and stands, theatre scenery and tradefares, as well as for strong shoring and support structures).
