Since their introduction in 1970, the type B70 sleeper is the mostly used prestressed concrete sleeper in the rail network of Deutsche Bahn. The sleeper can be used flexibly, has a load-bearing capacity of 25 tons, and allows for a maximum speed of 250 km/h. All this with just weighing 280 kilograms. Rail.One is also manufacturing the B70 sleeper at the Coswig factory near Dresden using a large circulation system.
B70 the most common prestressed concrete sleeper
The concrete railway sleeper of type B70 was developed by the central Bundesbahn office are manufactured and constantly improved by Rail.One. The company is part of the Indian PCM Group of Industries. The PCM Rail.One Group has been manufacturing concrete sleepers and track systems for more than 60 years now and operates eleven production sites all over the world.
In Germany, the B70 concrete track sleepers have been manufactured by Rail.One GmbH at the Coswig facility near Dresden since 1992. Owing to the surge in demand, the responsible managers at Rail.One decided to increase the production capacity for B70 at the Coswig factory considerably.
Capacity expansion without production downtime
The traction drives and the quadruple hoisting winch require a highly dynamic drive technology which runs very precisely. The plant control system of Weckenmann with integrated visualization controls all processes of the plant reliably and is linked with the existing circulation control system.
Being the general contractor, Weckenmann has also built the 54 m long factory hall – a steel structure with insulating panels for roof and walls. The capacity expansion in Coswig took place without requiring any downtime of the ongoing production. This would not have been possible without solid project planning and close collaboration of the project teams at Rail.one in Coswig and Weckenmann on a partnership basis.
