DLR / DHD - Underfloor Wheel Lathe

Underfloor wheel lathe for railway industry

The DANOBAT underfloor wheel lathe has been specifically designed for reprofiling railway wheels and brake discs. It can perform without the need to dismount the train axle and it is equipped with the most up-to-date technology.

A complete solution consisting of underfloor wheel lathe + software for optimisation of wheelsets + wheel profile measuring equipment.
Single or Tandem architecture and variable gauge optional or maximum adaptability.
Robust and reliable, providing a fully automatic machining process for rail wheels & brake discs.
Automatic hold-down device for inboard axle boxes.
High precision continuous contact measuring system.
Ease of use:

Simple and intuitive human-machine interface fully customised for the reprofiling for railway wheels and brake discs.
Smart Machining algorithms reduce cycle time, increase process reliability and safety and extend wheel life throughout the fleet.

Ease of installation: simple foundations, compact machine and fast installation.
Ease of maintenance
Offers multiple configuration possibilities for increased machining capabilities, such as machining of coupled wheelsets, reprofiling of individual wheelset & bogies, etc.

Complete solution machine + software + measurement

Range adapted to type of vehicle
