Hydraulics from Rexroth have been utilised in the construction of the Deriner Dam on the Coruh River in north-eastern Turkey. The drives have been used in an underground hydroelectric power plant comprising four turbines that will generate 2,100GWh.

Two large tilting gates, which feature Rexroth drives, provide flood discharge capability. The gates divert surplus water into the basin at the foot of the dam via two artificial diversion tunnels. Eight central outlet gates have been integrated into the main damn structure to cope with ‘flood of the century’ conditions.

As a project partner of ERG Trade and Industry, Bosch Rexroth was responsible for the drive and control system for the central outlet gates and the two tilting gates. The local branch office supported the conceptualisation, assembly and installation.

The opening drives for the central outlet gates represented a big challenge for the design of the hydraulic drives, as each gate measures 2.8 x 5.6m and weighs 24 tonnes. Despite this weight, the corresponding drives must work in parallel with a high degree of precision to ensure the gates always open and close in sync.

The answer was to mount the drive cylinders of the central outlet gates vertically in the drives.

Key benefits of product application

  • ERG Trade and Industry benefited from having just one partner for all flood discharge issues.
  • The drive cylinders are made of lightweight special steel.
