The new SK225SR-7 and SK235SR-7

Kobelco launches the new SK225SR-7 and SK235SR-7 short radius excavators with Tier 3 engines

Short Radius machines are ideal for operators working on urban and residential jobsites and are increasingly popular due to ongoing requirements for roadworks and utility maintenance. With this in mind, Kobelco Construction Machinery Australia is pleased to announce the addition of two new Tier 3 models to its extensive SR range. The new SK225SR-7 and SK235SR-7 follow Kobelco’s Performance x Design concept and offer powerful performance and productivity, precise controllability and excellent stability and lifting with the benefits of a Tier 3 engine.

Kobelco first introduced the Short Radius (SR) concept in 1996 and now has the largest SR range on the market covering machines from 1 tonne (SK008) to 38 tonnes (SK380SRLC). SR machines benefit from a smaller working footprint, which means that they can access tighter working areas and can even operate on one lane of highways, so as not to disturb traffic when working on roads or when lifting utility trench boxes.

The new SK225SR-7 and SK235SR-7 are equipped with a powerful 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.

Weighing in at 23.3 tonnes (SK225SR-7) and 25 tonnes (SK235SR-7), the new machines provide extremely precise operation through excellent controllability and smooth hydraulics. The optional heavy counterweights and balanced chassis layout delivers exceptional lifting capacity, which is ideal for heavier tools and attachments.

The new SR Series-7 machines 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 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 hands-free telephone. In addition, the jog dial controls multiple functions on the 10-inch colour 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.

Commenting on the introduction of the new Kobelco SK225SR-7 and SK235SR-7, Kobelco Australia’s General Manager of Product & Distribution, Mark Johnson, said: “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”.
