- If a bracket we made is wrong and does not fit your machine, we replace it.
How is the attachment mounted on this machine?
Tell us what is on the machine now. It narrows the sizes we show and goes with your enquiry. It does not confirm fit: we check the bracket before we send the quote.
These machines weigh more than 80 t, the limit of what we build to order. Send us the machine details and we tell you what we can build.
Before you order: check the interface
The weight class of the Komatsu PC750LC-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.
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.
- 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.

What the PC750LC-7 figures mean for its attachments
- The main pump delivers up to 988 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 2,945 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.
- Komatsu lists bucket capacities from 3.6 to 6 m³.
- Bucket breakout force is 362.8 kN and arm crowd force 298.1 kN. That is the force a bucket or ripper works with at the tooth.
- For transport it measures 13,030 x 4,210 x 4,615 mm (length, width, height).
- Engine power is 338 kW.
