THE BCR 100 bridge inspection and repair platform provides ready access to the underside of multi-track spans, avoiding the need for hanging scaffolding, or permanent rails supporting a travelling platform for inspecting each structure. The machine was designed specifically to meet a requirement set by substantial new bridges being erected under the project to convert ÖBB’s Wien - Salzburg main line into a four-track route suitable for 200 km/h.

The elevated working platform can accommodate three people and their power tools, for which supply outlets are available. The reach is remarkable, thanks to the double jib and two swivelling rings. The maximum working height above rail that can be reached is 23·7m, and this extends 10m either side of the track centre. Maximum lateral reach at lower levels is 17m.

The most remarkable feature is the ability to reach far underneath a span on which the BCR is standing. Work can be undertaken as far as 8m beyond the centre of track supporting the BCR in the direction away from the parapet over which the supporting arms must reach. At track centre, the platform can reach down almost 22m below rail.

The platform rotates through 180í, and the vehicle’s movement at 0 to 5 km/h can also be controlled from this location. An intercom links the platform with the vehicle operator.
