Krasnoyarsk Ship Lift: Russia's Unique Engineering Marvel
Located in Divnogorsk, Russia, the Krasnoyarsk ship lift (Russian: Судоподъёмник Красноярской ГЭС) stands as a remarkable feat of Soviet-era engineering. Situated at the Krasnoyarsk hydroelectric power station on the Yenisei River, this facility serves as the only boat lift in Russia, providing a critical transit point for vessels navigating the river's powerful currents and the massive dam infrastructure.
Key Facts
- Location: Divnogorsk, Krasnoyarsk Krai, Russia.
- River: Yenisei River.
- Operational Since: 1982.
- Designers: Developed by Lenhydroproject and manufactured by Lengidrostal.
- Unique Status: The only boat lift currently operating in Russia.
Engineering and Design
The construction of the Krasnoyarsk ship lift began in 1976, with the facility becoming fully operational in 1982. The system was designed to move ships across the dam while keeping them afloat, avoiding the need for traditional lock systems which can be slower or less efficient in specific terrains.
The lift's infrastructure is composed of four primary components: the outer harbor, the bottom of the approach channel, the lift mechanism itself, and a specialized turntable. The platform operates on an inclined rack railway with a substantial track gauge of 9 meters, powered by a high-capacity electric drive.
How the Ship Lift Operates
The process of transporting a vessel across the dam is a precise sequence of mechanical movements. At the heart of the system is a caisson—a watertight chamber or container that holds the ship and a volume of water.
- Loading: The platform is partially lowered below the water level, and a gate opens. The ship floats into the caisson, after which the gate closes, sealing the vessel and water inside.
- Ascent: The electric drive propels the platform up the inclined rack railway toward the crest of the hill.
- Rotation: Upon reaching the top, the platform enters a turntable. This mechanism rotates the entire platform to align it with a second track heading down the opposite slope.
- Descent and Exit: The platform is lowered into the upper tail waters of the Krasnoyarsk dam. Once partially submerged, the gate opens, allowing the ship to exit into the Krasnoyarsk Reservoir.

Frequently Asked Questions
What is the Krasnoyarsk ship lift?
It is a specialized boat lift located at the Krasnoyarsk hydroelectric power station in Divnogorsk, Russia, used to transport ships across the dam on the Yenisei River.
How does the lift move the ships?
The lift uses a watertight caisson on a platform that travels along an inclined rack railway. It carries the ship and water together, moving them up and over the dam via a turntable system.
Who built the ship lift?
The facility was developed by Lenhydroproject and manufactured by Lengidrostal.
When did the ship lift start operating?
Construction began in 1976, and the lift officially opened for operation in 1982.
Is this a common type of infrastructure in Russia?
No, the Krasnoyarsk ship lift is the only boat lift of its kind in Russia.
