Completed Projects

Design, manufacturing, operation and maintenance of hydraulic drives of electro-hydraulic remote-controlled control systems of Baikonur, Vostochny and Kourou launch sites

The Project goals are as follows:

  • Replacement of outdated electronics for up-to-date digital and microprocessor-based equipment to improve the quality of information displaying, to ensure more accurate diagnostics, to provide automated control of units and synchronous work of support trusses.
  • Replacement of outdated sensors for up-to-date digital ones to improve measuring accuracy and to simplify mechanical transmissions.
  • Use of advanced hydraulic components with built-in diagnostics and more flexible hydraulic systems to reduce installation and check-out time, and also to improve personnel safety.
  • Ergonomics improvement due to the enhanced automation of synchronization of support trusses and installation of pivoting platform.
  • Use of the pieces of equipment of the same type and modular design of electrohydraulic remote control system to ensure interchangeability and maintainability, design simplification and workability improvement.
