The large, specialised machines in this programme have one task: to move mountains. In the Fabero coal mine, northern Spain, you can see a 520-tonne Hitachi EX5500 hydraulic excavator making light work of overburden. This beast feeds 200-tonne capacity Cat 789C trucks in just three or four passes. Nearby, a Komatsu D475A dozer – the biggest in Europe – is ripping through rock. In footage from mines associated with Fabero you will see other immense hydraulic excavators at work: Komatsu PC3000 and Hitachi EX3600. Among the many supporting machines on view are Komatsu WA800 and WA600 wheeled loaders.
