Low-maintenance locking devices for moveable frogs

Within the scope of the new development of the integrative locking device EVZ for the Deutsche Bahn AG, also the new locking device for moveable frogs has been designed.

This is especially concerted to fit the particular and high requirements of moveable frogs and simultaneously provides all advantages of the low maintenance locking device EVZ.

The EVH does not only fit to the portfolio of DB-standard turnouts, but also enables CDP to provide tailor made solutions for entire turnout systems.

All advantages at a glance:

  • Reduces maintenance costs
  • Minimum lubrication
  • Adjustable clamp position
  • Temperature conditioned movement +/- 35 mm
  • Highest stability and reliability by using die forged components
