The IT revolution had a tremendous influence on the technology of construction equipment as well. The satellite operation management system was developed during the 90's as a method to supervise and manage equipment from a remote distance, and became an industry standard during this era.
Komatsu newly added 860E to the series of electric driven super sized Dump trucks.
Komatsu had been jointly developing a new electric driven system with Siemens of Germany, and 860E was the first model that was fitted with the Siemens electric component. The jointly developed device which consists of a generator, AC motor, inverter, reduction gear, etc. The combination of the advanced technology of the Siemens electric component and Komatsu's mechanical component, such as the reduction gear, realized high quality and reliability.
860E also came with an option of a trolley system. With a trolley system, a Dump truck gains high climbing ability using an AC motor for tapping into electricity from overhead lines above tracks at mines. This system also stretches the life of an engine and reduces fuel consumption by using self-generated electricity at mines rather than electricity generated by the engine.
860E was developed at Komatsu America and produced at its factory in Peoria, Illinois.
Load capacity: 254,000kg
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.
