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.


  • Railway, heavy haul, metro and light rail applications
  • Choice of electro-hydraulic or electro-mechanic drive systems
  • Up to four setting levels
  • Operation of turnouts with and without stretcher bars (track rods)
  • operation of swing nose crossings (moveable point frogs)
  • Reduced track downtime
  • Industry leading reliability and availability
  • Short and sturdy connecting rods with thermal expansion compensation
  • Low weight of components, no lifting gear required for installation
