Kobelco SK210LC-9 and SK260LC long reach: generations, units and lift charts

The SK210LC-9 is the shorter long-reach machine

Kobelco's North American long-reach bulletin separates the SK210LC-9's nominal 50-foot arrangement from the SK260LC-9's 60-foot front. Earlier comparison entries copied several SK260 measurements into the smaller model's column. The factory sheet instead gives the SK210 a shorter boom and arm, lower operating weight and different engine output.

A machine advertised simply as a “Kobelco long reach” needs its full model and front lengths established before selecting a transport or dredging plan.

The nominal reach label is not the measured digging radius. The bulletin distinguishes maximum reach, reach along the ground, vertical depth and the depth at which an eight-foot flat bottom is possible. Those limits describe different points in the work envelope.

A trench requiring its full bottom width at depth cannot be specified from maximum vertical depth alone.

Bucket selection changes with generation

The older Dash-9 sheet associates its lift charts with an installed bucket and named counterweight. The August 2019 Dash-10 booklet instead heads the comparable chart “Bucket: Less” and defines the lifting point at the arm bucket pin. That change matters when estimating available load: the bucket, coupler and other equipment still consume capacity.

A chart based at a bare attachment pin cannot be treated as a ready-to-use bucket-hook rating from the older document.

For the Dash-10 SK260, the bucket-selection table pairs ditch-bucket sizes with their own widths and empty weights. Its light-material condition limits the intended material density. The widest permitted bucket is therefore not automatically suitable for heavier wet spoil, and its empty mass must remain in the lift calculation.

Ask which actual bucket the seller has installed; a capacity stamped on another attachment does not establish the long-reach combination.

The Dash-10 chart lists its own counterweight, distinct from the Dash-9 chart's heavier entry. The older and newer charts consequently cannot be exchanged just because their nominal reach labels match. Neither chart grants the same capacity in every direction.

Side and front columns differ, as do capacities above and below ground level.

Read feet-and-inches as dimensions, not decimal feet

A minimum swing radius printed as 18 ft 4 in is not 18.4 inches, and 60 ft 10 in is not 60.10 decimal feet. The original manufacturer drawings state both the measurement name and its unit. The corrected comparisons preserve those pairs explicitly.

Shoe width had the same problem: the sheet's 31.5-inch track shoe is not a 31.5-foot component.

The SK260LC-10 booklet identifies the Hino J05E-UN engine and net output. “SK260LC” in the engine-model field was the excavator name, not an engine designation. Its published swing speed also differs from an earlier catalogue entry, so the document edition accompanies the correction.

The older values remain available as labelled historical entries; they are not silently substituted into a service instruction for another generation.
