Equipment Overview
The Kobelco SK55SRX is a 5.51-tonne mini excavator that packs more digging power and practical performance features into a small package while maintaining a short tail swing, suited to urban and residential jobsites needing a smaller working footprint. A larger boom and arm come as standard for a wide working range, and the Integrated Flow Pump System lets operators harness extra output from the third pump, normally used for swing and dozer functions, directing it to the arm and boom for faster, smoother raising even with heavy loads.
Power comes from a 37 hp Yanmar diesel meeting Tier 4 Final emissions standards. The redesigned hydraulic system shortens digging cycle time by up to 7% and increases travel speed by up to 12%, with hill-climbing speed up 10% over the previous generation. Kobelco’s proprietary iNDr cooling system keeps operation quiet and protects against dust, and the KOBELCO Performance X Design concept brings the same quality, feel and comfort as Kobelco’s larger excavator models to this compact machine.
