CAT340D2L is a classic 40-ton large crawler hydraulic excavator by Caterpillar. Equipped with a mature and reliable C9 ACERT engine and an efficient hydraulic system, the entire machine features a reinforced structure and a high ground clearance. It is specially designed for harsh working conditions such as stone excavation, mining, and heavy infrastructure construction, balancing high production capacity with low operating costs.
1.Powerful and highly efficient with low fuel consumption
Equipped with the Cat C9 ACERT engine (208kW/279hp), it is paired with an optimized hydraulic system, featuring greater digging force and faster cycle; compared to the previous model, it saves approximately 7%-9% of fuel, and is more economical in heavy-load conditions.
2. Enhanced structure, mining-grade durability
Utilizing HDHW high-strength components and thickened chassis, the track gauge is wider, the ground clearance is increased by approximately 65%, providing better shock resistance and wear resistance. It has a low failure rate and long service life in rocky environments.
3. Stable overload, safe and efficient
The total weight of the machine is approximately 38.9 - 41.5 tons. The counterweight is reasonable and the ground contact area is large, ensuring good stability during heavy-load lifting and side-hanging; the movement and rotation are smooth, and it is less likely to tip over in complex terrains, making the operation safer.
4. Maintenance is simple and downtime is minimal
Key components are modularized and maintenance points are concentrated. The oil/ filter replacement cycle is long; there is an abundant supply of global spare parts and complete maintenance manuals, making daily inspections quick and minimizing downtime.
