Installation unit of shock absorbing devices (IUSAD)

       IUSAD unit is designed for installation of shock absorbing devices of cars, locomotives and other rolling stocks. It performs works related with dismantling and installation of shock absorbing devices of all types. 
             Important features of this series:
  • Unit innovation design based on pantograph approach has significantly reduced unit weight and excluded the impact of side forces on lifting cylinder rod. Due to this design operational life of hydraulic cylinder drive seals has been significantly increased.
  • High-strength seals of composite material are used in the drive. Quality assurance is seals of leading global manufacturers.
