How a stonehenge-type challenge (i.e. the transportation of weighty components) is dealt with in 1949, using floating cranes and a special 24-wheeled British Railways wagon. Stonehenge rocks weigh, on average, 25-30 tonnes. The two roll housing assemblies seen here, for use in a strip mill in The Steel Company of Wales' new Abbey Works, weigh 115 tonnes each.
