Lifting of the invert arch formwork with a drive-over bridge, tunnel clearance Belchen

The whole drive-over bridge was set down with maximum precision. It was lifted with a 400 tonne heavy crawler crane over the space-consuming conveyor system and placed at its place of destination in front of the tunnel entrance. The carefully planned and well executed manoeuvre made it possible to move the bridge with the exceptional measures of a length of 35m, a lane width of 3.7m, an outer width of 10m and a total weight of 130 tonnes without any further troubles.
