The weight class of the Caterpillar 310 - Tier 4 / Stage V 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 310 - Tier 4 / Stage V at its weight are built with these brackets. Each code opens the models that list it.
Brackets we build attachments with in this weight range. Not a confirmed fit.
- 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 310 - Tier 4 / Stage V figures mean for its attachments
- Its auxiliary circuit is rated at 131 l/min and 285 bar. A breaker, auger, tilt rotator or other hydraulic tool states the oil flow it needs, so choose one whose range includes this figure.
- The main pump delivers up to 233 l/min at 285 bar. That is the pump output of the whole machine, not the flow an attachment gets.
- Caterpillar lists this quick coupler for it: Hydraulic Coupler for Cat Tools. The bracket on every attachment has to match the coupler.
- It digs down to 5,211 mm. That is the deepest trench it can open.
- Its maximum reach is 7,570 mm.
- It dumps at up to 5,829 mm, so a truck or skip side has to sit below that height.
- Its arm is 2,500 mm long.
- Bucket breakout force is 77.7 kN and arm crowd force 49.2 kN. That is the force a bucket or ripper works with at the tooth.
- Caterpillar gives a lifting capacity of 5,431 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
- For transport it measures 6,983 x 2,470 x 2,550 mm (length, width, height).
