The works yard of Meichle + Mohr as the day is dawning. Outlines of silos and conveyor belts, great mountains of gravel and grit. As if appearing from nowhere, the glaring LED lamps of the earthmover approach the tipper. A slight shudder – the first bucket-load of gravel rattles into the semitrailer, then another, then a third. “That's almost 27 tonnes. We always have to deal with heavy loads,” says Felix Amann. Just a quick trip to the weighbridge, then out of the yard in Radolfzell, a right turn and off he goes.
He's heading for Hegau, north-west of Lake Constance. In this region, volcanoes and ice ages left their mark over the course of millions of years – so the scenery is spectacular, but the topography is tough to navigate. It's a constant up and down, left and right, and a series of roundabouts, junctions, villages and heavy traffic.
