How buying works
- 01Inquire. Choose your machine and send us a message or give us a call. We'll get back to you as soon as we can.
- 02Confirmation. We check the digger's availability against your requirements, including any customisation you've asked for, and confirm how long it will take to get it to you.
- 0310% deposit. A holding deposit of 10% secures the machine before we ship it. Total time is typically 6 to 8 weeks from deposit to arrival at your door, confirmed with you in person and in writing.
- 04Balance on delivery. Pay the remaining 90% when we hand the machine over.
Frequently asked questions
What's the difference between a Cat 312 and a Cat 313 excavator?
The 312 is an 11 to 12 tonne digger; the 313 is 13 to 14 tonnes, digs deeper and carries a larger bucket. A Cat 312GC weighs about 11.6 tonnes and digs to 5.08 metres, compared with roughly 13.8 tonnes and 6.04 metres for a 313GC.
How do the Cat 320 and 323 compare?
Both weigh around 21 to 22 tonnes. The 323 makes up to 124 kW against 109 kW for the 320 and has a larger maximum bucket capacity.
How many hours is too many on a used Cat excavator?
We cap listed machines at 6,000 hours; most have 2,000 to 5,000. Undercarriage and hydraulic condition tell you more than the hour meter.
What should I check before buying a used Cat excavator?
Hours, undercarriage wear and hydraulics matter more than age. We clean and inspect every machine before import, then a qualified engineer inspects and signs it off before shipping.
How long does delivery take once I buy?
About 6 to 8 weeks from a 10% deposit to the machine arriving at your door, with the balance due on delivery.
