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 model met with the emission regulation of Japan/US/Europe. It was loaded with "STARE II-HST", the evolved version of Komatsu's original electric controlling system HST*, which provided variable pulling power depending on the road condition. The working conditions on snow was particularly improved using a setting of S mode (snow mode) for snow removal. The maintenance was made easy by adopting the hydraulic driven fan with the auto reverse function that reduced clogging of the radiator core.
ROPS/FOPS cab was a part of standard specs, securing safety of operators under emergency. The double sided pillar-less glass with fall preventing function was used for the front glass of the cab, which offered wider visibility.
* HST: Hydro-Static Transmission (hydraulic driven transmission)
Bucket capacity: 3.0m3
It was 1949 when the first wheel loader was manufactured in Japan, however, it was not until mid 1960's when Komatsu entered the wheel loader market aligning with International Harvester. From JH series in the beginning, to the 500 series, to Komatsu's original WA series, our wheel loaders have met the needs of construction sites by scaling up, coping with the environment and adopting advanced technology such as mechatronics and IT.
