Kobelco’s new mini excavators
By Andy Brown13 July 2021
Kobelco Europe has launched next generation mini excavators, SK50SRX-7 and SK58SRX-7, which the company says have increased performance, productivity and operator comfort.
The Japanese-based manufacturer said that the new release shows its continued commitment to developing its smaller machinery alongside its heavier equipment.
The all-new SK50/58SRX-7 machines benefit from a new hydraulic system which shortens the digging cycle time by up to 11%, and this high performance can be maintained without reducing speed, even with a heavy load or when travelling up a slope.
In addition, the replacement of the travel motor and swivel joint has increased the travel and hill climbing speeds by approximately 10%.
The new models replace the company’s SK45SRX-6E and SK55SRX-6E mini excavators.
Other benefits of the new hydraulic system include smoother operation and improved levelling performance. The Integrated Flow Pump System enables operators to harness extra output from the third pump, which otherwise powers the swing and dozer circuit.
This additional output is directed to the arm and boom for added power when digging, resulting in a fast and smooth raising operation, even with heavy loads.
Kobelco Europe product marketing technical manager, Tadayoshi Aoki, said, “Increasing demand for smaller machines means that mini excavators have become even more important to Kobelco’s overall product line-up.
“Many of the features included in our new SK50/58SRX-7 mini excavators, such as the iNDrsystem, have been tried and tested in our heavier machines first, while customer feedback also played a vital role in the development of these new mini machines. The SK50/58SRX-7 truly represent a new generation in Kobelco Performance x Design.”
