Logistic Support Bridging (LSB)

Logistic Support Bridging (LSB) is usually constructed with the aid of a crane, it provides a greater load carrying capacity than  Close Support Bridging (CSB) or General Support Bridging (GSB). One standard set contains all the components required to construct, launch and recover a bridge.

The modular design of the equipment means it can be constructed in a large number of different configurations, allowing the system to be used for a wide range of load and spans. The LSB can be deployed on Lines of Communication to provide new bridges, replace damaged bridges or to upgrade routes for heavier traffic.

The LSB overcomes limitations in width, span, capacity and fatigue life associated with many other systems. The LSB can be built by hand, but where cranes and other mechanical handling equipment are available, the total number of man-hours to build the bridge is substantially reduced.

Bridge components can be transported using DROPS flat racks and ISO containers.

The bridge can be constructed by a Royal Engineer Field Section. Once constructed a LSB tends to remain in situ for far longer periods than either a CSB or a GSB.

The bridge has a roadway width of 4.2m and can be built with sloping or level ramps depending on the site.

Logistic Support Bridge (LSB) Fixed Pier

The pier consists of 2 towers that are constructed from standard panels with the addition of some key components. The 2 piers are built independently, the pier caps are then craned into position to form a platform on which rollers are secured to allow the bridge to be boomed.
