Rail Milling Machine
Drive System
Secondary controlled drive of two milling wagons Synchronisation of 4 chassis with 8 secondary controlled units Traction control over 66 m train length with 300 t total weight At 0,3 – 2 km/h from 0,3 up to 10 mm milling depth
Absolute constant speed is neccessary for the planing of the rail profile. According to the rail condition normally 0,3..0,6 mm will be removed by milling. Service life of the 500 milling plates 1..6 km. Change time of the milling plates of the milling wheel 10 min.
Milling Wheel Diameter 1,4 m

Cranes With Secondary Controlled Drive Systems
Bosch Rexroth: More than 70 secondary controlled AHC cranes of TTS, Odim, Kenz and DMC in the market.
Operation fields e.g.: Laying of pipelines Milling of trenches on the seabed Installation of underwater manifolds
assemblies Support of submersible vehicles and
divers Huisman and SMST use also RAHC
systems with secondary control in their cranes. Up to now are ca. 250 secondary controlled units in use (2010).
