In Australia the Cat 730 is the mid-sized workhorse of Caterpillar's articulated truck line, bought mainly by civil and bulk-earthworks contractors, quarries and dam builders who need to move material where haul roads are soft, steep or unfinished. Used examples on the local market skew toward the model's earlier production run, concentrated along the eastern seaboard, and prices spread widely — condition and hour meter matter far more than build date at this age. Most trucks carry the standard dump body; tailgate-equipped units and the ejector variant surface occasionally, and later builds moved to an updated engine platform, which some buyers prefer for parts commonality. On any candidate, budget for a driveline inspection — transmission, differentials and suspension cylinders are the expensive items — and check body floor wear and centre-hitch play. Dealer parts support remains strong, which keeps tired but honest trucks saleable.
What a Cat 730 is used for
The Cat 730 is an articulated dump truck built to haul bulk material across soft and uneven ground where a rigid truck would bog.
- Muck-away and spoil haulage on civil sites
- Quarry and pit haulage
- Working soft, wet or uneven ground (articulated, all-wheel drive)
- Road, dam and bulk-earthworks haulage
What Moves the Price
Body & liner condition
A straight, lined body without cracked-out corners is the first thing valued on an articulated dump truck — body repairs are plate-steel money.
Component hours
Transmission, transfer case and diff hours matter more than the calendar. Documented mid-life rebuilds carry real value.
Mine-site disposals
Bulk mine and civil fleet disposals set the floor of the market. Machines with clean service files recover most of the gap.
Tyres
Six large earthmover tyres are a serious line item — tread remaining is quoted straight off the asking price on every ADT.
