Live’s Modular Bridges are the ideal access solution for a variety of situations and terrains, quick to install and incredibly strong.
- Technical Information
Comprised of separate components - base plate, parapets and width units - Modular Bridges can be connected together transverely to create different lengths and widths. The base plates can be pinned into the ground and also prevent separation of the units.
The bridges are available in multiples of 3.2 metre spans but the width is unlimited in multiples of 2.4m giving greater flexibility when working out carriage requirements. Speeds are restricted to 30mph when using the bridges but, if greater speeds are required this will be discussed on a site specific basis. Modular Bridges are installed using an appropriate sized crane, which will depend on the site and is decided prior to the installation. All of the spans have special lifting points to ensure a safe and controlled lift.
The units have been designed to Eurocode LM1 and LM2 load models to EN1991- 2:2003, Traffic loads on bridges.
LM1 is intended to cover flowing, congested or traffic jam situations with a high percentage of heavy lorries. In general, it covers the effects of a special vehicle of 60t axle load (2 axles spaced at 1.2m centres).
LM2 is a single axle load of 40t – used for the design of the decks. In short, the bridges can be used by any vehicle which can go on public roads without requiring notification of the local authorities. Notifiable loads (very heavy cranes etc.) can also go over the bridge units but this would be checked by Live prior to use.

How much are the Modular Bridges to rent?
POA – subject to site visit and dependent on the size required and the duration of hire.
What type of footings can the Modular Bridges be placed on?
The modular bridges are installed on their own base plates that interlock the modular components. The base plates can be placed a bank, timber, steel, concrete or hard-core. Our engineers can provide advice if required. However, as stated earlier, the design and construction of substructure is the responsibility of the client.
Can metal tracked vehicles run on the Modular Bridges?
Yes, if a protective material is placed on the surface or a PVC covering. Live can provide you with this product if required.
Does Live have Modular Bridges with shorter spans?
Live has trench crossings that span 4.0 metres & 6.0 metres that have been designed to Eurocode Load Model 3.
How far away does the Modular Bridge need to be from the edge of the bank?
The ground bearing capacity is the customer’s responsibility.
Can modular bridges be used on SSSi sites?
All units are thoroughly cleaned and inspected before they transported to site.
Can anything be connected to the parapet rails on the Modular Bridges?
Mesh panels or solid panels could be fixed to the parapet rail. Other items such as services could be placed on a cantilever bracket fixed to the outside of the bridge.
What type of surface does the Modular Bridge have?
Factory applied anti-skid surfacing suitable for all wheeled machines. In the case of tracked machines the surface needs to be protected.
Are the materials that the Modular Bridges are made of from sustainable sources?
Yes. The bridges are an all steel construction with polyurethane resin anti-skid surfacing, which are all from sustainable sources.
Is any training required for the use of the Modular Bridges?
Please see the reverse of this sheet, this states the dimensions, weights, lifting devices required and further general information.
How are the Modular Bridges tested and maintained?
They have been manufactured to the current Eurocodes, BSEN1090-2 – Execution of steel structures, plus they have been inspected for full compliance after fabrication and before dispatch to site.
The units are cleaned and inspected for any sign of damage after they are returned to the depot.
What are the weights of the Modular Bridges?
9.6 by 2.4m weighs (including parapet on 1 side) – 7976 kg
12.8 by 2.4m weighs (including parapet on 1 side) – 11584 kg
How are the Modular Bridges transported?
The modular bridges have been designed to on a flatbed artic, there is no need for a wide or extended load. Depending on the configuration, multiple units may fit on one artic.
Will the Modular Bridges rust when they come in contact with water?
The units are hot dip galvanised to provide a rust free, long and maintenance free life.
How can the Modular Bridges be lifted?
Live will install the modular bridges using an appropriate sized crane, this will depend on the site and will be decided prior to the installation. All of the spans have special lifting points to ensure a safe and controlled lift.
What type of terrain can the Modular Bridges be used in?
They can be used on any terrain, plus if there are access difficulties to get the bridge into place then Live can provide an access solution to suit the terrain.
Are the Bridges modular?
Yes, the base plate, parapets, and width units are separate components. All components are interchangeable and modular.
What speed do the parapets allow traffic to travel at?
The speed is restricted to 30 mph, if greater speeds are required this is possible and will be discussed on a site specific basis. Live’s modular bridge is the only system currently available with a complying parapet system.
Are the Modular Bridges CE marked?
All units have been manufactured by fabricators in the UK who are accredited for CE marking. All manufacturing has been carried out to the latest standards. Currently there is no harmonized standard for temporary bridges in Europe.
