Shipyard turntable — specialized transport system consists of supporting frame with the laid railtrack which are on the same grade with the ship handling lines.
Driveless shipyard turntable is intended to move block sections and ships while their building and repair. Transfer is effected from the lead track of one ship transfer area to another lead track of another ship transfer area.
While using shipyard turntables rather than slipways ship handling trolleys setout is conducted by the frame timber of the structure and ship projection and doesn’t depend from the railtrack setout on the cross-section platform.
Shipyard turntables of horizontal travel can have different load carrying capacity and length. It depends on a ship characteristics/submarines.
