The weight class of the Komatsu PC340LC/NLC-7 Demolition 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.DBS - engineered rock bucket for excavator

What the PC340LC/NLC-7 Demolition figures mean for its attachments
- The main pump delivers up to 536 l/min at 373 bar. That is the pump output of the whole machine, not the flow an attachment gets.document from images01.equippo.com
- It digs down to 7,120 mm. That is the deepest trench it can open.document from images01.equippo.com
- Its maximum reach is 12,375 mm.document from images01.equippo.com
- It dumps at up to 10,680 mm, so a truck or skip side has to sit below that height.document from images01.equippo.com
- Komatsu offers arms from 2,600 to 3,200 mm. A longer arm reaches further, a shorter one handles a heavier bucket.document from images01.equippo.com
- Engine power is 184 kW.
