MINI EXCAVATORS

KOBELCO minis prove that great things can come in small packages. These machines pack full-size performance into a highly portable frame. A minimal rear swing radius with zero tail overhang allows for excellent handling in confined spaces while a simple design makes routine maintenance easy.

SK55SRX-6

  • Engine Power - 28.3 kW (37.9 hp)
  • Operating Weight - 5,020 kg (11,068 lbs)

Now KOBELCO has taken the next evolutionary step by packaging even more digging power and practical performance features into the SK55SRX-6 while maintaining a short tail swing.

The Energy Conservation Mode saves even more fuel, and KOBELCO's proprietary iNDr Cooling System ensures quiet operation, protection from dust, and easy maintenance.

For greater operator comfort and safety, the spacious cab design offers plenty of room and an unobstructed view. It all adds up to enhanced full-size performance, short-radius agility and a low-noise environment, with exceptional performance features and a full range of value-added functions.
