No titles. Giant earth movers.
Birmingham, West Midlands.
Various shots of an enormous tyre being lifted out of a mould and being tested at a factory. An engineer looks at the progress on a closed circuit television screen (CCTV).
A huge earth mover stands beside a mini car. The earth mover moves off slowly.
At an open-cast coal site at Widrington, Newcastle-on-Tyne we see several shots of the earth mover at work. The vehicle stops beside a man - the wheel is taller than he is. Another earth mover is seen at work. It comes towards camera and turns, having just deposited a load of earth.
