While equipment built to accommodate urban environments, by generating less noise, vibrations and emission, became more common, super sized equipment that could withstand harsh working conditions in places like giant mines were also developed.
Komatsu America had developed and produced Dump trucks of the "Hallpack" brand, the former merger partner. 930E, an electric driven dump, was one of them and it was the world's largest at that time.
Diameter of tire: 3.7m, load capacity: 320,000kg
The history of the dump truck as a transporting vehicle is also the history of increasing the amount of loading to improve productivity at construction sites. At mines especially, new technology is being introduced consistently even today. Enlarging the size by mechanical and electrical formulas, and adding the GPS control system are some of the examples.
