History

    In 1994, Euclid-Hitachi Heavy Equipment Inc. was established. After the acquisition of 100% of the shares, the name was changed to Hitachi Construction Truck Manufacturing (HTM), and the production of 40-350 tons rigid dump trucks was transferred from the United States to Canada.

The company continued to grow, and in 2008 another Rinko plant with an area of 181,500 square meters was built near the city of Hitachinaka. It manufactures mining excavators EX470 - EX870 and EX1200 - EX8000, as well as dump trucks EH3500ACII - EH5000ACII.

In the same year, one of the largest dump trucks manufactured in Japan, the EN3500AC-2, was produced with a rigid frame and an AC electric drive. It was based on Hitachi Ltd.'s latest development for that year, based on inverter technology used in Shinkansen-type bullet trains.

Strengthening its position in the construction equipment market, Hitachi acquired a full stake in Kawasaki Construction Machinery in 2015. This has contributed to the expansion of the wheel loader range.

Hitachi always has a high social responsibility, follows the concept of “lean manufacturing” and strives to minimize the harmful impact on the environment. This is the driving force behind the development of machines that use less energy, last longer and are made from recyclable materials. Dump trucks and electric excavators are just a few of these developments. So, in 2011, the ZX35B mini-excavator appeared with battery power. In the same year, a new generation of ZH200 hybrid excavators was launched in Japan. Drawing on experience in the development of hydraulic excavators, battery equipment and electrical equipment, the company created the Trias-HX hybrid system. Thanks to the advantages of the hydraulic and hybrid systems, 20 percent fuel savings have been achieved.

Continuing to innovate, Hitachi follows the Japanese philosophy of "kaizen", which is based on the idea of continuous improvement. In 2012, the company began testing the first autonomous dump truck that can move around the site without operator involvement. This technology has significantly reduced operating costs in mining operations as well as improved safety.

All manufacturing processes at Hitachi are based on the Monozukuri System, a Japanese manufacturing philosophy, a comprehensive concept of ideas, principles and activities that create safe and efficient operation at the factory site. The essence of this philosophy lies in the 5S production system: shine, sort, organize, standardize, self-discipline.

The success of the electric motor fueled the desire of Namihei Odaira and his team to pursue new developments. In 1949, they produced the first U05 cable excavator, completely using Japanese technology. In 1965, the first UH03 hydraulic excavator was introduced, which, thanks to a new development with two pumps and two valves, increased the productivity of operators by simultaneously raising the boom and turning the excavator. Market counterparts did not have such a function. Many manufacturers took note of the new idea, using at that time standard European designs with one pump and one valve. Thus, Japanese technologies began to gain worldwide popularity.
