Cat 330D vs Doosan DH300 for mining — which?
Cat 330D/336D2 costs USD 45,000–95,000 with unmatched parts support; Doosan DH300/DX340 delivers similar tonnage at USD 38,000–75,000. For remote African sites, Cat's parts availability usually wins.
Price vs tonnage
| Model | USD range (FOB Shanghai) |
|---|---|
| Caterpillar 330D / 336D2 | 45,000 – 95,000 |
| Komatsu PC300-8 / PC360 | 48,000 – 92,000 |
| Doosan DH300 / DX340 | 38,000 – 75,000 |
| Sany SY305 / SY335 (Chinese) | 32,000 – 58,000 |
The trade-off
Doosan moves similar tonnage to Cat for meaningfully less money, and Doosan parts are strong in Korea-linked markets. The differentiator is parts support at your site: for a remote mine in Africa, Cat's 175-dealer network is often the difference between a machine back to work in days versus weeks.
Our guidance
If uptime is the priority and the site is remote, pay the Cat premium. If you're in a market with solid Doosan/Komatsu support and want to save capital, the Korean machines are excellent value.
Is Doosan reliable for mining duty?
Yes — DH300/DX340 units are proven in quarrying and heavy earthwork. The main variable is local parts and service depth, not the machine itself.
What about a Chinese 30-ton (Sany SY305)?
A Sany SY305 at USD 32,000–58,000 is the cheapest entry, but expect weaker resale and parts outside major Chinese-equipment markets.
Which 30-ton holds resale best?
Caterpillar, consistent with its dealer network. Doosan holds less, which is part of why it is cheaper to buy.
