We are a reliable and competent partner supplying our customers with bridge building equipment of all types. Our extremely flexible modular systems form the basis for our many movable scaffolding systems, conventional scaffolding, towers and scaffolding supports. Working with our customers, we use our special know-how to develop project-specific, individual solutions to ensure technically and economically efficient operations on site.

From concept to construction, structural design to delivery and assembly of loadbearing scaffolds on site – LGB can satisfy your every need from our own resources.

Special bridges need special services: In addition to our main areas of work, we also provide a wide range of special constructions and customised solutions.

Conventional scaffolding

The most common type of scaffolding is the conventional stationary scaffold. This usually consists of support girders running in the longitudinal direction of the bridge, which are carried by trestles. The support girders normally take the form of 3D trusses, plane trusses or rolled steel sections. The modular LGB truss girders can span without intermediate supports clear across bridge spans of to 40 m. Very large or varying span lengths can be constructed using intermediate trestles. Stationary LGB scaffolding is also suitable for industrial and architectural structures for supporting heavy loads at great heights or spanning over large areas that must be kept clear.

standard scaffolding

Our conventional scaffolding is notable for its great flexibility. This allows bridges with any cross-sectional shape, longitudinal or transverse gradients and a wide range of plan geometries to be constructed.

The customer benefits from a comprehensive stock of materials and our years of experience in scaffolding.

Moveable scaffolding systems

Moveable scaffolding systems - Gänsebach

A movable scaffolding system (MMS) is a special scaffold that is mainly used to construct long bridges with more or less equal distances between their supports. In addition to short manufacturing times, this form of scaffolding has the advantage that only enough formwork to complete one segment of the superstructure needs to be provided. After concreting, the formwork and the supporting girders advance to the next segment of the superstructure.

LGB’s portfolio includes truss modules with a wide range of load capacities that can be flexibly combined to create movable scaffolding systems to suit your requirements. Whether overhead or underslung, rigid or articulating formwork crossbeams, ground-supported tower trestles at the sides of piers or supports fixed to piers, with or without the use of suspended support arrangements at coupling joints – we collaborate with our customers to develop project-specific solutions for optimum use of material and an efficient construction programme. Our movable scaffolding systems are suitable for the construction of bridges with a wide range of cross sections and spans between 20 m and 70 m.

The typical sequence of operations when using a movable scaffolding system is given below:

  • Erect the scaffolding including trestles
  • Install formwork
  • Fix reinforcement and concrete the 1st segment of superstructure
  • Lower the scaffolding including formwork
  • Advance to the next pier trestle
  • Install the suspended supports at the coupling joint
  • Raise the scaffolding including formwork to the required final height
  • Activate the suspended supports at the coupling joint
  • Fix reinforcement and concrete the 2nd segment of superstructure
  • Lower the scaffolding, etc. …

Special Constructions

In addition to our main areas of work, i.e. conventional scaffolding and movable scaffolding systems, we can also provide a broad spectrum of special constructions. Our well-coordinated team of engineers, erectors and fitters also supply creative and efficient solutions to solve the trickiest of problems.


At the request of customers, we develop special underslung formtraveller systems, which offer great advantages, including clear access to the working area from above without obstructions such as transverse girders or suspended support assemblies. Our customers gain from improved workflows and accelerated construction times.

Temporary supports for bridge demolition

Where bridges need to be demolished without damaging their valuable and sensitive surroundings, we can provide our customers with special demolition scaffolding. This allows machines to demolish bridges above a stationary conventional scaffolding platform or the superstructure of valley bridges to be demolished using movable scaffolding systems. If the customer wishes, we develop, design and implement special demolition concepts based on the use of hydraulic equipment. Our technical expertise combined with a close working relationship with structural engineers specialising in assessing the stability of partially demolished structures, we can always provide an economically efficient and structurally safe demolition solution.

Bridge lifting / bridge moving

Drawing on our skills in combining our scaffolding and hydraulic equipment, we are always pleased to offer our customers tailor-made structural solutions for raising bridges, lowering superstructures or sliding new bridges built adjacent to their final locations into position.

As well as cooperating closely with a wide range of formwork suppliers, we can provide our own special solutions for complex, clear-spanning formwork integrated into the loadbearing scaffolding structure.

Temporary bridges

Our modular system of support girders and steel components is very suitable for manufacturing temporary bridges of all types.

Bridge assessment

Working with our consulting engineer partners, our in-house, RVS-certified bridge inspectors perform assessments of bridges on local and regional roads and motorways in Austria.

Bridge assessment


Our technical department with its highly trained engineers is available to advise customers at the tendering, planning and execution stages. We develop concepts, analyse and complete structural designs for special projects. For every task, no matter how complex, we can provide a suitable solution, optimised both technically and economically.
