Spillway dam of the Dnieper Hydroelectric Station. Installation of the water lock manufactured by PJSC “UKRSTAL CONSTRUCTION” for the Customer PJSC “UKRHYDROENERGO”.

Transportation of the 62-ton water lock to the spillway over the dam using a special gantry crane with a lifting capacity of 2x100 / 50 + 15t, followed by installation in the design position, lifting the repair lock and applying the full working load on our main water lock.

Technical parameters: water lock mass 62 t, dimensions 14130 x 2370 x 11200 (h) mm, design load on the lock 724 tons, design lifting force 116 t, design water head 10.25 m, travel wheel diameter 820 mm (8 pieces), maximum wheel load 136 t, three-layer anti-corrosion system by Welesgard (zinc-filled primer and polyurethane coating with a total thickness of 230 microns with a 15-year guarantee).

The water lock was completely made by us at the facilities of "Structural Steel Fabrication Plant UKRSTAL Dnipro": starting from welded structures to completeness with seals and the whole set of attached equipment (including our own manufacture of balancing trolleys - running wheels, axles, upper balancers, balancer supports, etc.). Our own technology applied for the assembly of individual segments of shutter with control assembly on leveling plates in the factory conditions, with the pre-installation of balancing trolleys and seals, with geodesic survey and control of the general and detailed geometry of the structure.
