Start here

The attachments buyers in your market ask for first, sized for the PC240LC-7SLF.

Which coupler is on your machine?

Pick the system on your machine and we put it in your enquiry. We check the bracket before we send the quote.

How to measure your coupler

Not sure which system it is? Three measurements tell us which bracket you need.

Measure the diameter of both pins.
Measure the distance between the pin centres.
Measure the width between the inside faces of the ears.

If the coupler has a make or type printed on it, send that too.

Send me the spec sheet for my machine

What the PC240LC-7SLF figures mean for its attachments

Its auxiliary circuit works at 186 bar. Check that any hydraulic tool you add is rated for that pressure.
The main pump delivers up to 440 l/min at 373 bar. That is the pump output of the whole machine, not the flow an attachment gets.
It digs down to 14,580 mm. That is the deepest trench it can open.
Its maximum reach is 18,250 mm.
It dumps at up to 12,860 mm, so a truck or skip side has to sit below that height.
Komatsu lists buckets from 750 to 950 mm wide for this machine. Compare that with the bucket widths in the table above.Our sizes in that range: DB - heavy duty digging bucket (DB-300); DBF - flat-top digging bucket for quick coupler (DBF-300); DSX - Nordic heavy duty digging bucket (DS-HD-300)
Komatsu lists bucket capacities from 0.47 to 0.68 m³.
Komatsu gives a lifting capacity of 1,500 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
For transport it measures 14,400 x 3,180 x 3,230 mm (length, width, height).
Engine power is 125 kW.

Before you order: check the interface

The weight class of the Komatsu PC240LC-7SLF 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 Komatsu PC240LC-7SLF at its weight are built with these brackets. Each code opens the models that list it.

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