Kobelco SK Excavators: What the Letters SR, LC and NLC Mean, the Generation Number, and Track Tension as a Used-Buy Check Point
Kobelco marks its crawler excavators with the SK prefix. The "Kobelco Hydraulic Excavator" bucket holds 52 models, from compact machines up to the 850 class (SK850LC), spanning 62 to 380 kW.

LC denotes a wider, elongated undercarriage (more ground contact on soft terrain), while NLC ("Narrow Long Crawler") is the narrower counterpart for tight jobsites — both appear on models such as the SK350LC or SK480LC. SR ("Short Radius") is Kobelco's own design for minimal rear overhang: on SR models like the "115SR" or "135SR LC", the tail extends only about 185 mm past the tracks, which suits confined urban sites.
A separate ED line, such as the ED150 or ED190, combines an excavator with a 6-way dozer blade in one machine.
The digit after the hyphen (e.g. SK200-8) marks the generation — Kobelco has now reached generation 10 and 11, each bringing revised engine and emissions technology. When buying used, the generation number is worth checking: parts and control software aren't always compatible across generations.
On the track undercarriage itself, a used-buy check should also cover track tension: tracks that are too loose come off the rollers more easily on rough ground and speed up wear on the track links and rollers, while tracks pulled too tight increase load on the drive sprocket and idler wheel.
Cylinder count (3 to 6) and displacement (952 to 15,241 cm³) further indicate the size class.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Check the weights in the papers against the figures here — attachments change them.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
