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.
This was a fully changed model of D375A that had been used for large engineering works, crushing stones, and in mines.
It is outfitted with a new engine that had an increased rate of output compared to previous models. The newly shaped blade and the end bit with superb digging ability achieved higher productivity. Also the automatic gear changing power line with auto lock up controller system that had an excellent power transmission rate achieved groundbreaking low fuel consumption.
It had a new monitor panel with a more complete trouble shooting function. An operator was immediately notified about any emergency, showing how to manage the problem with four-step codes that would prevent serious troubles in advance of failure.
Since its first emergence in 1951, it took only 50 years for the hydraulic shovel to establish its primary position on construction sites worldwide. Its size ranges from mini to super size depending on the scale of construction, and during the half century, it kept evolving by achieving a minimum rear-swing radius and adapting styles that would work with characteristics of each site. Mirroring the movement of a human hand, a hydraulic shovel will continue to evolve during the 21st century.
