The WBG ONE-STOP SOLUTION: MODULARITY REDEFINED

The Waagner-Biro Beam Bridge Goliath WBG is a modular steel bridge system for single spans of up to 40 m, designed and developed for heavy traffic loads (Eurocode) and a high number of fatigue load cycles. The beam bridge is suitable for both temporary and permanent applications.

Arriving preassembled, this bridge is easily lifted in by crane and thus ideal for heavy traffic bridging, construction sites and disaster relief operations.

Variable deck widths

Different deck widths (single and multi-lane) can be achieved by laterally coupling the 2.50m wide beam bridge modules. Available are single lane bridges, double lane bridges and multiple lane bridges with any number of lanes. Optional cantilever footwalks are available in widths of 1.0 to 2.0m.

Clear spans of up to 40 m

Module lengths of 7.5m, 10.5m and 13.5m can be combined with each other as required.

Bridge combinations

Beam bridge modules are interconnected with one another to form any bridge span required. Bridge combinations up to 40 m are possible.

Simple and quick to build

• Beam bridge modules are equipped with integrated lifting lugs.

• The WBG is (fully or partly) pre-assembled at the factory and delivered to the site on flatbed trucks. It is lifted or launched into position and ready for immediate use. Optionally, Waagner-Biro is pleased to offer assembly and disassembly of the bridge.

• Optimal solution for temporary use: Multiple disassembly and reassembly of the bridge is easily possible.

• The WBG is ideal for over-bridging an existing bridge with low load-bearing capacity.

• The low construction height allows for the assembly of bridges without any costly ramping.

• All connections of the bridge structure are bolted.

• No welding is necessary on the construction site.

High Quality Standard

• Designed for high traffic loads and fatigue stresses according to Eurocode.

• Use of high-strength steel grades.

• CE certified design according to EN 1990-2 EXC 3.

Specifications for the Waagner-Biro Beam Bridge GOLIATH

• Type of construction: Modular construction with few individual components. The WBG consists of prefabricated modules which are interconnected longitudinally and transversely to achieve the required bridge length and width.

• Standard module lengths: 7.5 m, 10.5 m, 13.5 m

• Standard module width: 2.5 m

• Maximum clear span: 40 m

• Multi-span bridges: Designed as continuous girders on intermediate supports.

• System height incl. bearing: approx. 1.3 m

• Load standard: Eurocode

• Bridge deck and deck surface: Closed steel deck with orthotropic steel deck plate. Factory applied anti-slip surface made of epoxy resin with grit. All beam bridge modules are provided with lifting lugs.

• Guard rails and parapets: Guard rails comply with various restraint classes according to EN 1317. End pieces allow the transition to a landside guard rail. Stable curb elements on both sides of the carriageway.

• Walkway (outside the clearance gauge): Cantilevered construction; bolted to the guardrail construction by means of head plates.

• Walkway widths: 1.0 to 2.0 m.

• Railing height: up to 1.3 m.

• Bearings: Fixed and sliding bearings made of steel.

• Manufacturing: Execution according to EN 1090-2 EXC 3.

• Bolted connections: Beam bridge elements are bolted together by means of butt strap joints and pre-stressed high-strength bolted connections (HV).

• Corrosion protection: Main structure, guard rails, parapets: Hot-dip galvanised in accordance with EN ISO 1461. Bridge deck: Protected with three layers of coating on top of one another, all in accordance with current standards (C5 corrosion protection class - highest protection class).

• Assembly: Lifting with a mobile crane or by incremental launching.
