Frequently asked questions
What does a 12 to 15 tonne excavator weigh?
Operating weight runs from about 11.6 to 13.8 tonnes, depending on model and configuration. A Cat 312GC weighs 11.6 tonnes, a Hitachi ZX130-5A 12.7 tonnes and a Cat 313GC 13.8 tonnes.
Is a Cat 312GC a 12 tonne excavator?
The 312GC spec sheet gives 11.6 tonnes, just under 12 tonnes. It's sold in the 12 tonne class, so we list it alongside 13 to 15 tonne machines.
What can a 12 to 15 tonne excavator dig?
Dig depth is about 5 to 6 metres, with bucket capacity from 0.5 to 0.7 cubic metres, enough for foundations, drainage runs and general civil work beyond a compact machine's reach.
What's the difference between a Cat 313GC and a Hitachi ZX130-5A?
The Cat 313GC digs deeper at 6.04 metres against 5.54 metres for the ZX130-5A. The ZX130-5A has more engine power at 69 kW against 54 kW.
How many hours is too many on a used excavator in this class?
Every machine we list is under 6,000 hours, most between 2,000 and 5,000. We clean and inspect each before import, with a qualified engineer signing it off before shipping. Undercarriage wear says more about remaining life than the hour meter.
Why is the 12 to 15 tonne excavator size so popular in New Zealand?
Terra Cat, New Zealand's Caterpillar dealer, says 13 to 15 tonnes is the most popular size sold here, at up to 40% of sales in the 13 to 50 tonne range (source: terracat.co.nz). Contractors choose it once a compact machine is too small.
