Additional Information
The Kobelco SK12SR stands out in the sub-2 tonne class due to its pilot-controlled joystick levers, which provide smooth, precise operation comparable to much larger excavators. The hydraulic retractable undercarriage can shrink to just 850mm to pass through narrow doorways, then expand to 1,000mm for enhanced stability during operation. Additionally, the boom swing function allows for efficient digging parallel to walls, while the rear-mounted engine and swing-open bonnet ensure simplified daily maintenance access for Australian operators.
