The lid of a blast furnace needed to be trasported to the city Peine. The truck could not use the exit of the highway because of the diameter of 8,50 meters.
Our 200 tons crane came to help: the lid was lifted from the truck and could use the exit fo the highway without a problem. After that, the lid of the blast furnace was placed back on the truck.
Because this mission - with a full stoppage of the highway and support of the police - happened at night, it looked like an UFO landing to the audience.
