At mining sites, which require high productivity, long production stops due to machinery failure are unacceptable.
Furthermore, the roads used for transporting minerals are unpaved and frequented by service vehicles as well.
Advanced technology ensuring safety, durability, productivity and more is required of machinery operating in the harsh environment of a mine.
The biggest strength in Hitachi Construction Machinery’s mining business is that all development and production are concentrated in Japan. The keyword is “One Hitachi.” Sonosuke Ishii, president of Mining Group says the following.
“Our company marshals the comprehensive strength of the Hitachi Group to develop and manufacture products for mining. By concentrating our hubs in Japan, we can collaborate with the research and development divisions of all the companies within the Hitachi Group and make maximum use of the various products and technologies that the Group possesses.”
For example, the group jointly developed the technology featured in its dump trucks for transporting loads stably and safely (see page 9 about High-Performance Stability Control Technologies), applying automobile technology owned by Hitachi, Ltd. The dump trucks’ Autonomous Haulage System (AHS), too, uses Hitachi, Ltd. technology, such as the railway traffic control system it has developed over many years.
“Different mining sites have different priorities: at some the performance of dump trucks on inclines is taken very seriously, whereas others require braking power for going down slopes with loads of ore. To accomplish all this, Hitachi Construction Machinery doesn’t just buy from another manufacturer to install key parts of dump trucks like the AC drive system, but develops them with Hitachi Group technology. Being able to adjust to specifications required by our customers’ sites because of this is a big strength of ours,” explains Ishii. The benefits of “One Hitachi” are truly maximized this way.
