Bridge build for Sennebogen

Russian construction company BaltMostStroy used its Sennebogen 7700 crawler crane to help build an 800 metre bridge in Russia.

The bridge forms part of the new A121 motorway between St Petersburg and Priosersk-Sortavala. The 300 tonne capacity crawler crane was used to lift prefabricated steel parts weighing up to 100 tonnes onto the concrete foundations.

The 7700 was configured with a 41 m boom and auxiliary jib. It has an 8 m wide crawler undercarriage and 135 tonnes of ballast. A 313 kW Caterpillar diesel engine powers the two 220 kN winches.

Challenges during the bridge build included hilly terrain and extreme inclines, a spokesperson said. Around 10 more bridges will be built along the route.

Russian sales and service partner, LLC Lonmadi Saint Petersburg, delivered the new Sennebogen 7700 to BaltMostStroy in October 2013.
