XXL gantry

55 metres in just six and a half minutes

In early December, the longest gantry ever to leave the Forster works at Waidhofen was set up at the A6 motorway next to the South Nuremberg interchange.

The gantry is of the truss type and was built to a span of 54.75 metres and a weight of 48.58 tons. Due to the excessive transport height the beam was delivered in two parts and assembled on site. The job was handled by a team that included QSG Verkehrstechnik GmbH and Grimm GmbH & Co KG.

Installation in record time

Grimm carried out the installation works in the night between 1 and 2 December 2016 – and they did it in record time: the A6 motorway had to be closed down in both directions for just six and a half minutes. This logistic master stroke called for the superior project competence shown by the Forster Group in its traffic engineering capacity: once a contract is accepted by Forster, all parties involved sit down together to minutely plan all project activities. They draw up the clearance documents, compute the structural analysis, plan the materials and equipment required and specify the installation procedure. Services of the Forster team also include negotiations with traffic authorities and site supervision.
