These are port (dock) cranes. There were several of them, one of them was floating. With their help ashore crushed stone and sand, cement and other materials for the liquidation of the accident at the Chernobyl nuclear power plant. With their help, a dam was built separating the dirty lake from the Pripyat River.
Now these cranes are abandoned. They have a radiation background of about 600 microR / hour. They live on birds, cormorants.
Every year you can see that the details of the cranes disappear, despite the high level of radiation. On a quiet pier on the river bank, only a few rusty old port cranes remind that there was once a new cargo port.
Inside the cabin of the driver of the port crane. It is all polluted by birds and there are many plants inside. This cargo port was intended to provide all necessary for the construction of new power units (5th and 6th reactors) and a modern city of nuclear power engineers.
After the Chernobyl disaster, the fate of this port was predetermined. All this area, all the equipment here, and all four cranes were used to receive cargo for the elimination of the consequences of the accident at the fourth reactor and the structures and materials for the construction of the first Sarcophagus.
Сейчас эти громадные металлические гиганты заброшены и забыты, а плавучий кран и вовсе исчезает под водой, и скоро лишь груды металлолома будут напоминать об их существовании.
