Kobelco Adds Two Tier 3 Models to Its Short Radius Range

Kobelco has added two Tier 3 models to its Short Radius (SR) excavator range: the SK225SR-7 and SK235SR-7, weighing in at 23.3 tonnes and 25 tonnes respectively.

The SK225SR-7 and SK235SR-7 are equipped with a Tier 3 engine without the need for a DPF or AdBlue, which provides 127 kW output and 22% higher torque than previous models for a more efficient performance. No DPF or AdBlue results in lower owning and operational costs and less downtime for maintenance.

The new machines provide precise operation through controllability and smooth hydraulics. The optional heavy counterweights and balanced chassis layout deliver enhanced lifting capacity, which is ideal for heavier tools and attachments.

The new SR Series-7 machine arm and bucket cylinders have been reinforced, providing more digging power and durability. The plate thickness of the arm has been increased by 25% (1.25 times stronger than the previous generation model). The bucket cylinder has been reinforced by enlarging the flange and increasing the rod side pin diameter from 80 to 85 mm.

As part of Kobelco’s Performance x Design concept, the SK225SR-7 and SK235SR-7 also benefit from enhanced cabin design, ergonomics and safety features. The Kobelco-branded Grammer air suspension seat moves together with the armrests and hydraulic controls for the reduction of operator fatigue and provides excellent shock absorption and superior ride comfort.

The spacious cabin is also equipped with a DAB+ radio, Bluetooth and hand-free telephone. In addition, the jog dial controls multiple functions on the 10-inch color screen, including operating history, maintenance cycle, fuel and water temperature gauges as well as hydraulic oil-flow adjustment. To improve visibility on the jobsite, particularly when operating during the darker winter months, the new SK225SR-7 and SK235SR-7 have also been equipped with two bright LED work lights.

“Increased requirements for urban infrastructure, utilities and roadbuilding means an increased demand for compact machinery. The new SK225SR-7 and SK235SR-7 provide the same powerful performance and lifting capacity as our mid-weight conventional machines but with a smaller working footprint of just 4.05m (SK225SR-7) and 3.68m (SK235SR-7). The two new SR-7 models build on the legacy of the legendary -2 series machines with upgraded performance, productivity and comfort while maintaining the Tier 3 engine without DPF or AdBlue meaning lower operational and maintenance costs.”

said Kobelco Australia’s General Manager of Product & Distribution, Mark Johnson.
