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.
This is the very first mini shovel. It was also the first of the PC series born after the partnership between Komatsu and Bucyrus expired.
The biggest difference from regular sized Hydraulic excavators is adaptation of a boom slide system and boom swing system with side ditch digging. When the PC series was introduced in 1980, the model number of this mini sized unit was changed to PC20.
Weight: 2500kg, Bucket capacity: 0.05-0.13m3
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.
