What the 313 GC figures mean for its attachments
- The main pump delivers up to 247 l/min at 350 bar. That is the pump output of the whole machine, not the flow an attachment gets.
- Caterpillar lists this quick coupler for it: Cat Pin Grabber Coupler. The bracket on every attachment has to match the coupler.
- It digs down to 6,040 mm. That is the deepest trench it can open.
- Its maximum reach is 8,660 mm.
- It dumps at up to 6,420 mm, so a truck or skip side has to sit below that height.
- Caterpillar offers arms from 2,500 to 3,000 mm. A longer arm reaches further, a shorter one handles a heavier bucket.
- Caterpillar lists buckets from 450 to 1,200 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-160); SDB - heavy duty skeleton DB bucket (SDB-160); DBF - flat-top digging bucket for quick coupler (DBF-160); RDBF - flat-top skeleton DBF bucket on rods (RDBF-160); CB - heavy duty hydraulic clamp bucket (CBR-190)
- Caterpillar lists bucket capacities from 0.2 to 0.76 m³.
- Caterpillar gives a lifting capacity of 7,250 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
- For transport it measures 7,780 x 2,490 x 3,190 mm (length, width, height).

Before you order: check the interface
The weight class of the Caterpillar 313 GC 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 Caterpillar 313 GC 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.
