Low maintanance locking device for moveable frogs - EVH

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

Roller device for moveable frogs - RVH

The low-maintenance and lubrication free roller device for moveable frogs RVH is a corollary of CDP's standing experience in the area of switch roller systems RV and is developed to achieve a significant and sustainable reduction of maintenance- and repair costs of the technically demanding frog area.

With a low construction height, the RVH is designed to suit also for turnouts with narrow space conditions and can be installed in both new and existing turnouts.

The closed frog nose rests constantly on the slide chairs. During movement, the frog nose is lifted up by the roller device. The usual lubrication of all slide chairs is not necessary.

CDP roller systems are available for every kind of rail section, fastening type and inner bracing system.

All advantages at a glance:

  • No lubrication required
  • Significant reduction of throw-force
  • Simple and fast adjustment
  • Small payback period
  • No impairment of mechanical tamping
  • Environmental friendly (No lubricants)
  • Low construction height < 40 mm
  • Suitable for solid slab track
