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
213

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

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

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

What the PC750LC-6 figures mean for its attachments

  • The main pump delivers up to 1,008 l/min at 313.8 bar. That is the pump output of the whole machine, not the flow an attachment gets.
  • It digs down to 8,450 mm. That is the deepest trench it can open.
  • Its maximum reach is 13,400 mm.
  • It dumps at up to 8,235 mm, so a truck or skip side has to sit below that height.
  • Komatsu offers arms from 2,900 to 3,600 mm. A longer arm reaches further, a shorter one handles a heavier bucket.
  • Komatsu lists buckets from 1,750 to 2,920 mm wide for this machine. Compare that with the bucket widths in the table above.
  • Komatsu lists bucket capacities from 3.6 to 6 m³.
  • For transport it measures 13,820 x 4,110 x 4,785 mm (length, width, height).
  • Engine power is 331 kW.

Before you order: check the interface

The weight class of the Komatsu PC750LC-6 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.

Heavy excavators dig rock, load trucks and work in quarries, so wear decides the bucket as much as capacity does. Rock and reinforced buckets carry thicker wear steel, teeth and side cutters, and the bucket is sized to the trucks it loads and to the density of the material.

  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.
