Bridge and lock gates installed in Dover docks
A single leaf bascule bridge and marina lock gates have been installed at the Dover Western Docks Revival (DWDR) development.
The bridge, designed and manufactured by Qualter Hall, has been installed by Qualter Hall on behalf of VSBW, a joint venture of VolkerStevin and Boskalis Westminster, which has a £115m contract to deliver the marine structures and bridge contract for the Port of Dover project.
The bascule bridge has been designed to maintain vehicle and pedestrian access along the Esplanade. It spans the new navigation channel connecting the existing Wellington Dock with the new marina that is being built in in the outer harbour.
The bridge deck is attached by tie bars to a pivoting arm that sits on a pair of masts, designed to represent ship masts. The deck is lifted by hydraulic cylinders that are attached to the pivoting frame. The lifting mechanism is assisted by a steel-filled counterweight section at the end of the balance arm.
The deck is 16 metres long and 15.1 metres wide. It weighs 96 tonnes. It has a mast height of 16 metres and was brought in by a sea-going barge from the fabricator, Victor Buyck, in Belgium. It was lifted into place by a 1,250-tonne rated Liebherr mobile crane.
