With an operating weight of 25,000 kg, the SK235SR-7 is robust enough to handle heavy-duty digging while remaining agile in confined spaces. 

Its short tail-swing radius (1,720 mm) ensures stability and safety when working near obstacles—ideal for urban construction or tight infrastructure projects.

The machine’s 6,650 mm dig depth and 9,680 mm reach at ground level provide impressive flexibility, whether trenching, loading trucks, or shaping embankments. 

For those working to precise grade requirements, the 6,470 mm dig depth to cut a 2,440 mm level bottom ensures accuracy in foundation work.

At the heart of the SK235SR-7 is a Yanmar 4TN107TT turbocharged engine, compliant with Tier 3 emissions standards and capable of running on B5 biodiesel. There is also a T4f-compliant version available. 

Delivering 127 kW (170 hp) at 2,000 rpm, this 4.5-litre, four-cylinder powerhouse ensures strong performance while keeping fuel consumption in check.

Hydraulic efficiency is another key strength, with axial piston, gear, and pilot pumps working in harmony to deliver smooth, responsive operation. 

The system’s 343-bar relief valve pressure and dual 220 L/min main pumps (plus a 41 L/min auxiliary flow) provide the muscle needed for demanding attachments, from breakers to grapples.

Kobelco’s commitment to operator comfort is evident in the SK235SR-7’s spacious, ergonomic cab. 

Low noise levels, intuitive controls, and excellent visibility reduce fatigue during long shifts. 

The excavator’s 5.2 km/h travel speed and 70% gradeability ensure quick repositioning on steep or uneven terrain.

With a standard 0.8 m³ bucket capacity (1,160 mm width), the SK235SR-7 is optimised for bulk material handling. 

Its 14,581 kgf bucket breakout force and 10,401 kgf arm breakout force make light work of tough digging conditions. 

The inclusion of a spare spool for attachments adds further versatility, allowing quick adaptation to specialised tasks.

Transporting the SK235SR-7 is straightforward, with a transport length of 9,730 mm, width of 2,990 mm, and height of 3,180 mm. 

The 600 mm track pads distribute weight evenly, minimising ground pressure—critical when working on soft or sensitive surfaces.
