Used Caterpillar Dump Trucks: Dumpers & Spare Parts

Purchasing a used Cat dump truck is a significant investment — which is why transparency about the machine’s condition and the general sales terms is essential. At Codimatra, every machine is described in detail to help you compare offers with confidence.

Caterpillar dump trucks stand out for their exceptional lifespan, often exceeding that of their direct competitors. A well-maintained 740 articulated model can remain fully operational for several decades, making the used market especially attractive.

To extend the service life of your equipment, the availability of genuine Cat spare parts plays a decisive role. Engine, transmission, dump body or hydraulic system: every critical component must be quickly replaceable to minimize downtime on your job sites.

Used Cat Dump Trucks: Available Models

• The Cat range includes two main categories: articulated dump trucks for rough terrains and rigid trucks for long hauls.
• Articulated models like the 730 or 745 offer capacities from 28 to 45 tons of payload.
• The 740 is especially favored on quarry sites due to its versatility and off-road handling.
• On the rigid side, the 777 carries up to 100 tons, while the 797F reaches 363 tons in mining configuration.
• Each model available at Codimatra comes with detailed technical data: engine hours, year, and maintenance history.
• The model choice mainly depends on the volume to be transported, terrain type, and access dimensions on site.

Articulated Dump Trucks: 730, 735, 740, 745

The Cat articulated series consists of four complementary models, each sized for different volumes and operating conditions. The 730 is the most compact in the range, designed for job sites with restricted access where maneuverability is prioritized over raw tonnage.

The 735 offers a higher dump body capacity, while the 740 features a six-speed automatic transmission that significantly reduces operator fatigue during long shifts. The 745, the top-tier articulated model, can achieve impressive unloading speeds thanks to its optional dump ejector system.

These four models share an oscillating articulated chassis design, allowing all six wheels to remain in contact with the ground even on uneven slopes—a key advantage in open-pit mining or earthworks embankments.

Rigid Dump Trucks: 777, 785C, 797F and Payload

• The 777 is powered by a Cat C32 engine delivering close to 1,000 horsepower for intensive hauling tasks.
• The 785C is mid-range with around 150 tons capacity, suitable for medium-sized mines.
• The 797F is driven by a Cat C175-20 engine with 4,000 horsepower, making it one of the most powerful dump trucks worldwide.
• The 785C’s seven-speed automatic transmission optimizes fuel consumption over long hauling cycles.
• The 797F requires reinforced road infrastructure on site, with specially designed tracks to support its full loaded weight.
• The rigid chassis of these models allows higher transport speeds on prepared roads, unlike articulated trucks.
• On the used market, the 785C is frequently sought after for its balance between transport capacity and controlled operating costs.

Does Caterpillar Manufacture Dump Trucks?

The answer requires a clear distinction. Caterpillar does not produce on-road dump trucks in the traditional sense—vehicles registered to operate on public roads. Cat’s specialty lies in off-road site dump trucks, designed exclusively for mining, quarries, and major earthmoving projects.

However, there are two notable exceptions: the CT660 and CT681, on-road truck tractors developed by Cat, which were sold mainly in the North American market. These models, now reproduced as 1/50 scale miniatures by Diecast Masters, mark the brand’s occasional foray into the road segment.

For over 50 years, Caterpillar has built its global reputation on off-road dump trucks, with machines operating under extreme conditions across all continents.

Spare Parts for Cat Dump Trucks: Quarry & Construction Trucks

• Oil filters, belts, and dump body seals are among the consumables most frequently replaced on Cat dump trucks.
• Every Cat part is identifiable by its OEM reference number, ensuring exact compatibility with the specific model.
• Wear parts like dump body floor plates are heavily used on high-tonnage quarry sites.
• Having critical spare parts stocked onsite reduces machine downtime from days to just a few hours.
• Hydraulic components—tilt cylinders and hoses—require systematic checks every 500 operating hours.
• Some parts, such as bucket teeth or track pads, are common across several Cat models, simplifying inventory management.
• Choosing certified Cat parts over generic equivalents preserves manufacturer warranties and resale value.
