Construction Machinery - Machines that used to make building, digging surfaces and sweeping rubbish are called "Construction Machinery"
Heavy Equipment - Heavy equipment refers to heavy-duty vehicles, specially designed for executing construction tasks, most frequently ones involving earthwork operations. They are also known as, heavy machines, heavy trucks, construction equipment, engineering equipment, heavy vehicles, or heavy hydraulics. They usually comprise five equipment systems: implement, traction, structure, power train, control and information. Heavy equipment functions through the mechanical advantage of a simple machine, the ratio between input force applied and force exerted is multiplied. Currently most equipment use hydraulic drives as a primary source of motion.
1940s - The history of Japan's construction equipment started after World War II.
For the restoration of land, mechanization was implemented for construction work concerning electric power and land development for forest conservation and flood control, etc.
In 1948, the Ministry of Construction budgeted the construction equipment maintenance expense and brought about the full scale development of construction equipment.
1950s - The Japanese economy entered the high growth period and the government executed public works focusing on the national life and the development and maintenance of industrial foundation.
Construction equipment has contributed to the development and maintenance of the social infrastructure such as traffic networks including roads, ports and railroads, forest conservation and flood control including dams and sand control dams as well as water resource development, agriculture land development, land improvement work, etc.
Private enterprises also made sizeable equipment investments for the improvement of industrial sites, construction of plants and maintenance of industrial waterworks, in which many construction machines were used.
1960s-The economy shifted from the high growth period to the stable growth period. In order to realize richer living standards, maintenance of living environment such as water and sewerage, parks, etc., was carried out.
Construction equipment played an important role to realize a rich living environment.
Development for compact machines such as the mini excavator suitable for use in small city environments increased.
1970s - Development for compact machines such as the mini excavator suitable for use in small city environments increased.
For the creation of a better city environment, new construction equipment such as special attachments for the demolition of decrepit buildings in need of redevelopment, propulsion machines that lay sewerage pipes without having to excavate roads, etc., were developed.
By use of electronic control and utilization of new materials and technologies, performance was greatly improved and development of equipment also superior in design was started.
1980s - Under the new concept the "City harmony and user-friendly machines," full-scale development of equipment superior in design, comfort and controllability was launched.
Stronger correspondence to the earth environment is being made including such issues as emission regulation, complete banning of specific halon, CFC and trichloroethane, etc.
Towards the Future - The industry has carried on research and development on intelligent machines, like robots, in its effort to develop unattended or remote controlled systems utilizing artificial satellites in the near future.
Construction machinery mainly includes excavator, loader, dozer, paver and crane. Today’s construction machines are more reliable, easy to port and easy to operate; but the operators are required to have proper training. Some of the world famous construction machinery Japanese brands : Komatsu, Hitachi, Kobelco, Kato, Sumitomo, Mitsubishi, Aichi, Caterpillar, Furukawa, Hanta, IHI, Isuzu, Sakai, Tadano, Takeuchi, Toyota, TCM, Yanmar etc.
