DLR/DHD
UNDERFLOOR WHEEL LATHE FOR PASSENGER TRAINS
Specifically designed and manufactured to reprofile wheelsets mounted on a train or bogie, as well as single wheelsets.
-
DLR (single and tandem version | max. axle load: 18000 kg) for: metro, tram, commuter, high-speed
-
DHD (single and tandem version | max. axle load: 30000 kg) for: commuter, locomotive, high-speed
Technology
When it comes to quality, every detail matters

Full cast iron machine structure
- Better long-term stability than fabricated steel
- Vibration damping
- Handles temperature variations
Cross slide assemblies
Incorporates tool holders and measuring devices. Accurate and reliable linear guideways.
Measuring system
Specialised system for measuring wheel diameter and wheel profile geometry. Compact design integrated in a single measuring head. Retractable to protect against chips during machining.
Wheel drive system
- Four wheel drive rollers with hydraulic lift
- Continuous contact between the roller and the wheel
- Vibration absorption
Axial guiding system
- Two guide rollers to maintain the axial position of the wheelset
- Hardened steel rollers
- Automatically controlled position
- Automatically lubricated
