The Janson Bridging supply programme includes a range of bridge systems. All Janson Bridging products are designed and developed in house. The temporary modular bridge systems consist of plate girder bridge systems that can be coupled longitudinally or laterally, beam bridge systems with low-profile coupling, customized construction bridge systems, and adapted and hybrid panel bridge systems. All bridge solutions can be supplied and installed in line with the measurements specified by our customers, from lightweight cycle and pedestrian bridges to heavyweight traffic bridges in large spans of up to over 100 metres. All products are delivered with the accompanying technical drawings, latest Eurocode calculations, and CE certification.
Janson’s Beam Bridge sections (code JSK) are designed for temporary and permanent use in situations wherever short-span bridges up to a maximum length of 21 metres are required for general traffic. The special coupling system and integrated lifting lugs mean that the pre-assembled Janson Beam Bridges can be installed quickly, saving time and money. The low profile of the bridges reduces the need for long approach ramps. The Janson Beam Bridge is the ideal system for spanning over roads or waterways as soon as the capacity of an existing bridge is temporarily insufficient. The Janson Beam Bridge complies with the Eurocode.
Janson's Plate Girder Bridges (code JSB) are designed for temporary or permanent use, particularly in areas of heavy traffic where free spans of up to 40 metres are required. Janson's Plate Girder Bridges are designed and manufactured for rapid and simple construction. The bridge sections are transported to the building site, lifted into position and bolted to create a complete bridge in minimal construction time. The sections can be connected longitudinally or laterally and offer a vast range of spans and road widths.
Janson Paneel Bridge system (code JPB) is designed for temporary and permanent use wherever bridges with a span of up to 80 metres (262 ft) for general traffic are required. The system is based on the original Bailey Bridge concept and uses trusses assembled from modular panels. The individual components are designed to be constructed using light tools, thereby enabling the panel bridge to be installed on sites that are inaccessible to heavy vehicles and heavy cranes.
Janson's Truss Bridge system (code PSB) is a bridge intended for permanent use and was particularly developed for rural areas where infrastructure and transport facilities are limited, for emergencies (floods, earthquakes) and for peacekeeping operations. The external appearance, combined with the high quality structure, makes this bridge system an increasingly popular option for permanent solutions in developing countries.
Janson’s Modular Pedestrian Bridge range consists of two systems: the Janson Pedestrian Panel Bridge system and the Janson Pedestrian Truss Bridge system.
Janson's Pedestrian Panel Bridge system (Code JPB-Ped) is designed for temporary and permanent use wherever light traffic bridges with a span of up to 61 metres are required. On sites that are inaccessible to telecranes, the bridges can be erected using the standard cantilever launch method.
Janson’s Pedestrian Truss Bridge system (Code PSB-Ped) was designed for permanent use wherever pedestrian bridges with a span of up to 48 metres are required. The Pedestrian Truss Bridge is a modular system with longitudinal trusses is built up using standard interchangeable components in modular lengths of 4.0 metres. All components are bolted together using standard fasteners.
