D-HOB 4.0 – mobile rail machining for turnouts in specially monitored track quality
The specially designed D-HOB 4.0 for point treatment combines a rotational planer and block grinder for the first time. The machining of up to 1.5 mm per passage is totally free of sparks and dust. The chips are sucked off immediately and bunkered in the block grinder. The rail head’s transverse and longitudinal profiles are manufactured as per EN 13231-3:2012. The machining marks run in the rail’s longitudinal direction. Once the rail machining is finished, roughness values are available at a level below the limits as per TSI+ and ISO 3095. It is not necessary to run the rail rolling surface in.
As a result, the “specially monitored track” system can be realised in turnouts for the first time too. The machine can be used on high-speed tracks up to 300 km/h, heavily used freight train routes and local railway and underground networks night and day.
High performance rail milling machine – HSM
The HSM –the new generation of milling machines
Schweerbau has extended its portfolio of machines for the mobile rail treatment by a high-performance milling machine. The HSM (High-Speed Milling machine), a milling machine of the next generation, is the result of our proven collaboration with our long-term partners Mevert Maschinenbau GmbH, Lauenhagen (work engineering) and Gleisbaumechanik Brandenburg / H. GmbH, Kirchmöser (vehicle engineering). The HSM has been approved by the German Railway Authority EBA and in April 2016 obtained its clearance by DB Netz AG.
