Before you order: check the interface

The weight class of the Kobelco SK140SRD-7 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.

At this weight the choice is mostly about the material. A general purpose bucket suits soil and gravel, a reinforced bucket with thicker wear parts suits mixed ground and broken rock, and the quick coupler on the machine sets the bracket every attachment needs.

Quick coupler brackets at this weight

In our model tables, the attachments listed for the Kobelco SK140SRD-7 at its weight are built with these brackets. Each code opens the models that list it.

Brackets we build attachments with in this weight range. Not a confirmed fit.

  1. Measure the diameter of both bucket pins.
  2. Measure the distance between the pin centres.
  3. Measure the inside width between the stick ears.
  4. If the machine runs a quick coupler, note its make and type.

What the SK140SRD-7 figures mean for its attachments

  • Its auxiliary circuit works at 245 bar. Check that any hydraulic tool you add is rated for that pressure.
  • The main pump delivers up to 260 l/min at 343 bar. That is the pump output of the whole machine, not the flow an attachment gets.
  • Its tail swing radius is 1,600 mm, which matters beside a wall or in a live traffic lane.
  • Engine power is 71.3 kW.
