In combination with zentrak - Intelligent Diagnostic Platform, our intelligent turnout is an extremely effective tool for your maintenance team.

Worldwide under various environmental and operational conditions, the UNISTAR HR family proves market leading quality and reliability. All family members offer watertight and dust-tight boxes certified according to IP67. The unique and SIL4 certified design of UNISTAR HR is proving excellent reliability and highest availability in daily operation.

Technical description:

  • Motor unit and DLD (drive, locking, detection) unit are split into two individual IP67 certified boxes. This allows versatile installation.
  • The motor unit with hydraulic drive is capable of operating up to four DLD units installed in a turnout.
  • In case of distributed drives in a turnout, identical DLD units are applied.
  • The throw of each adjustment level can be individually adjusted

The connecting rods compensate for thermal expansion and contraction of the switch points without affecting the end position adjustments. Integrated pressure heads positively close the switch points against the stock rail.

Benefits:

  • Prepared for zentrak – Intelligent Diagnostic Platform
  • Equipped with Remote Vital Inspection (RVI) to extend inspection intervals
  • Low Life-Cycle Costs
  • Operation of turnouts with and without stretcher bars (track rods)
  • One drive serves up to four setting levels
  • Operation of swing nose crossings (movable point frogs)
  • Reduced track downtime
  • Short and sturdy connecting rods with thermal expansion compensation
  • Low weight of components, no lifting gear required for installation
