What the SK75SR-7 Offset Boom figures mean for its attachments
- It digs down to 4,600 mm. That is the deepest trench it can open.
- Its maximum reach is 6,620 mm.
- It dumps at up to 5,660 mm, so a truck or skip side has to sit below that height.
- Kobelco offers arms from 1,760 to 2,060 mm. A longer arm reaches further, a shorter one handles a heavier bucket.
- Kobelco lists buckets from 400 to 870 mm wide for this machine. Compare that with the bucket widths in the table above.Our sizes in that range: GP - general purpose digging bucket (GP-95); GPO - GP bucket with perforated bottom (GPO-95); GPL - general purpose digging bucket (GPL-95); GPLO - GPL bucket with perforated bottom (GPLO-95); BDP mini - clay digging bucket for mini-excavator (BDP-90); PDP mini - skeleton BDP stone bucket (PDP-90); DS mini - Scandinavian deep digging bucket for mini-excavator (DS-90); KS mini - cable bucket for mini-excavator (KS-100); KSV mini - Scandinavian profile cable V bucket for mini-excavator (KSV-100); CB mini - hydraulic clamp bucket for mini-excavator (CBR-90)
- Kobelco lists bucket capacities from 0.11 to 0.35 m³.
- Bucket breakout force is 60.1 kN and arm crowd force 35.8 kN. That is the force a bucket or ripper works with at the tooth.
- Kobelco gives a lifting capacity of 2,790 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
- Its tail swing radius is 1,380 mm, which matters beside a wall or in a live traffic lane.
- For transport it measures 6,190 x 2,300 x 2,570 mm (length, width, height).
- Engine power is 52.3 kW.

Before you order: check the interface
The weight class of the Kobelco SK75SR-7 Offset Boom sizes the attachment. It does not tell you the pin diameter, the pin spacing or the stick width, and those decide whether an attachment fits. Measure them on the machine, or send us the measurements of the bucket it runs today.
A midi excavator is often the main machine on a site, trenching, loading and grading in the same day. Buyers usually start with a general purpose bucket, a grading bucket and a quick coupler, then add other tools when the work calls for them.
