1970
Since this era, the focus of domestic demand gradually started shifting from bulldozers to hydraulic shovels. Additional considerations, such as ease of operation, also became an important aspect of design.
In order to improve quality of the previous model 15H, 15HT was developed with major remodeling. The biggest remodel was that it was equipped with the same tracks as a bulldozer. (T in HT stands for tractor's feet) This improved durability, mobility, and workability in damp and soft areas drastically.

Hydraulic excavator
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.
