Bauer supply gear motors for crane used to construct the longest cable-stayed bridge in the world

A crane manufactured by Mostovik Crane has been specially designed to complete a huge regeneration project of Russky Island, Russia, aimed at developing the area into a large-scale, contemporary tourist resort.

The development included the construction of a cable stayed bridge that would connect the island to the mainland Muravyov-Amursky Peninsula.

The unique crane was required to operate under extreme weather conditions including high speed winds and temperatures of -30°C during the winter months. Bauer was chosen by Mostovik to deliver suitable geared motors to complete the construction of the crane.

The Bauer BF Series geared motors, with torques form 10100 – 13400NM have set new standards for dependability and efficiency and were chosen for the total flexibility they provide as they can be mounted in any required position.

Bauer’s geared motors were particularly well suited to the Russky Island bridge application guaranteeing absolute reliability as they are concealed to IP65 as standard (IP66 optional) against dust and water spray.  The geared motors also provide comprehensive corrosion protection.

The erection of the bridge’s central span, made up of a hundred and three panels and weighing a total of twenty three thousand tonnes, was one of the most challenging phases of its construction, with the last section being lifted into place on April 2.

The completed structure is the world’s longest cable stayed bridge; reaching 70m above water level, stretching 1104m at is central width and pylons 320m in height supporting stay cables 580m in length.

In September, 2012, the regenerated Russky Island site will host the 24th meeting of the Asia-Pacific Economic Cooperation (APEC) leaders.
