For residential areas and industrial premises, you need a machine that can manoeuvre and swing within a compact radius, allowing easier operation adjacent to fixed objects and walls. The SK12SR is designed to do just that, with smooth, powerful control and excellent stability, this machine offers full-scale performance in a compact size. With a 180° working radius of 1.7 m, SK12SR only needs minimal space to dig, swing, and load continuously. The boom swing angles of 45 degrees to the left and 85 degrees to the right for optimized performance when digging pipeline ditches and side walls.
The pilot operated joystick controls provide precise and comfortable control of the machine, just like a larger excavator, for relaxed all-day operation.
Crawlers can be easily extended and retracted by operating a simple lever. Capable of passing through spaces as narrow as 830 mm wide, the SK12SR can be used on a wide variety of urban and industrial jobsites. The hydraulic retractable side frames are durable and self-cleaning.
The cast steel upper frame with integrated counterweight is designed to withstand impact to front corners during swing operation. The backfill dozer blade has wear-resistant cutting edge for long service life, while providing further lateral stability.
Boosted swing power and a top-class swing speed deliver shorter cycle times.
Max. Arm Crowding and Bucket Digging Force: 6.6kN | 13.7kN
Swing and Travel Speed: 10.0 rpm | 4.0/2.1 km/h
Like all Kobelco mini excavators, the SK12SR comes with a standard 4 year/4,000 hour Full Machine Warranty.
