Komatsu mid size hydraulic excavator HB205-2

BH205-2 is a newly launched mid size hybrid hydraulic shovel that meets the 2011 off-road engine emission standards. It is equipped with the new generation engine that meets the emission regulation in Japan, North America and Europe. In addition, it improves fuel consumption by decreasing loss of the main valve oil pressure circuit of the body, employing a large-capacity high efficiency hydraulic pump and high efficiency hydraulic fluid.

It also improves safety, preventing falls during maintenance and inspection and reducing the theft risk with newly adopted anti-fall hand rail and the ID key. The new generation 7-inch HD LCD monitor ensures safe, accurate and smooth work and its display of the eco-guidance supports the energy efficient operation.

Hydraulic excavator OPEN

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.
