Contractor Mostovik used Doka self-climbing formwork to construct the world's tallest A-shaped tower - part of a 1.1 km suspension bridge linking Russky Island with Vladivostok on the Russian mainland.

At 320 m, construction of the World's tallest A-shaped tower has been completed - part of a 1.1 km suspension bridge that will link Russky Island in the Golden Horn Bay, Russia, with Vladivostok on the Russian mainland.

The four-lane motorway bridge is being built as part of the preparations for the Asia-Pacific Economic Forum (APEC) meeting in September this year.

Contractor Mostovik used Doka self-climbing formwork with 650 m² of made-to-measure Top 50 beam formwork to construct the tower.

The extremes of the geographic location, with frequent stormy weather and bitter cold in the winter months, had a major influencing factor on the build.

Doka's adaptable SKE50 automatic climbing formwork was used inside the tower legs, where space was at a premium, and SKE100 with its high load-carrying capability was used to climb the outside walls.

Rated at 10 tonnes lifting capacity per bracket, it allows for craneless lifting of the beam formwork assemblies and seven different platform levels.

The climbing falsework was anchored to the structure at all times, so craneless, safe lifting of formwork and platforms could proceed in virtually any weather, according to Doka.
