484 DRY DOCK 2 – NEW DOCK GATE – FLAPGATE

SPECIAL FEATURES
In order to work as a dry dock, the gate and seals are compressed onto the civil works by hydrostatic head once the dock has been pumped out. In order to work as a wet dock, the gate is closed and the latching pins are engaged which hold the top of the gate in position and keep pushing the seals against the civil works by mechanical force. The hinge point at the bottom of the gate will keep the bottom part in position.
