| Mining Operation, Africa | Doosan DX420LC-5 | Rock excavation | Enhanced material handling and minimized delays due to rough terrain. |
| Building Construction, UAE | Doosan DX225LC-5 | Lifting and transporting materials | Faster project turnaround and improved safety standards. |
These examples demonstrate the importance of a Doosan Crawler Excavator in the construction project. They are working in tough places and doing the hard tasks people don’t want to do.
Case Study 1: Highway Expansion, USA
In the U.S., there’s a project working to expand a highway. They are doing massive earthwork including excavation and cut and fill grading work across a dragline-type job on rough terrain. What did they turn to to solve this production problem? A Doosan DX300LC-5. With its maneuverability and power, the DX300LC-5 is a great machine for this dragline type job in uneven terrain. The hydraulic power and engine horsepower of this 75,000-pound machine pushed more dirt in less time in this cut and fill job. Plus, the hydraulic control system, the engine system, and the computerized GPS design helped the operator manage his fuel usage to this day.
Outcome:
- Increased work efficiency by 20%.
- Reduced project time by a significant margin, saving the contractor money on labor and equipment rental costs.
- Enhanced safety due to the machine’s stability and robust undercarriage.
Case Study 2: Mining Operation, Africa
In Africa, over in a desert, rocky environment, they were using a Doosan DX420LC-5 on a mining project. Most people equate mining with hauling, but there is significant excavation and site preparation that happens before they can load material. Most bucket excavators really struggle out there in that tough terrain. However, with the larger bucket capacity, more powerful hydraulics, and super high hydraulic flow on a DX420LC-5, they were able to pull that rock faster, smoother, and handle more material than any other machine they had on site. This thing was eating rocks all day long until they loaded the truck with it, so that made everyone look good and made the mining operation more efficient.
Outcome:
- Enhanced material handling capabilities, allowing for higher productivity with fewer delays.
- Reduced downtime due to the machine’s durable components designed to endure harsh environments.
- The long-lasting durability of the excavator minimized the need for frequent repairs and maintenance, leading to reduced overall operational costs.
Case Study 3: Building Construction, UAE
In Dubai, they are building high rises. To do that, they need somebody with a good looking design on their hard hat to lift and carry a lot of heavy stuff to put up a high-rise hotel or a bridge or whatever you can think of in their construction marketplace. Doosan DX225LC-5 lifts and carries material all day long. How do they do that? They lift by the hydraulic efficiency system, by lifting so quickly to maintain the schedule without ever wrecking a load or somebody getting hurt. That’s how they move tons of material every hour of the day, all the way through the safety tram acts and all the guidelines all those countries are requiring they operate under.
Outcome:
- Faster project turnaround due to the DX225LC-5’s ability to work long hours efficiently.
- Improved safety standards as the excavator’s stable and balanced design reduced the likelihood of accidents during material transport.
- The low operating costs of the DX225LC-5 made it a cost-effective choice for the construction company, providing a strong return on investment.
These examples are proof points of how Doosan Crawlers work every day. They are working on a highway job in the USA that has a lot of excavation on it. They are working in Africa where it looks like a war zone with the amount of material that’s been moved using those big rock trucks. They are working in Dubai where tens of thousands of people from Bangladesh and India build high-rises in one of the most rugged job sites in the world. What are they using to do those jobs? Doosan Excavators.
Doosan Crawler Excavators vs. Competitors: Which Is Best for Heavy-Duty Work?
When you compare Doosan Crawler Excavators to other machines in the industry such as CAT, Komatsu, and Hitachi, two possibilities emerge. Either people will look at the same variables we’ve been talking about—do you have enough power, fuel efficiency, lowest cost to maintain, and the value of getting around the job and getting the work done—allowing the Doosan to win the fight in the construction company’s mind. Or, they’re comparing apples to oranges, and they have other drives, commitments, or incentives to do it some other way.
Here’s a detailed breakdown of the features of Doosan Crawler Excavators compared to other top brands:
| Feature | Doosan Crawler Excavators | CAT Crawler Excavators | Komatsu Crawler Excavators | Hitachi Crawler Excavators |
|---|---|---|---|---|
| Engine Power (HP) | 173-276 | 160-350 | 160-330 | 170-350 |
| Hydraulic Flow (L/min) | 570-720 | 500-700 | 530-730 | 510-700 |
| Bucket Capacity (m³) | 1.2-2.0 | 1.0-2.5 | 1.1-2.3 | 1.0-2.4 |
| Fuel Efficiency | High efficiency, lower costs | High performance, but higher cost | Reliable, but costly in the long run | Cost-effective with good ROI |
| Maintenance Cost | Lower maintenance costs | Higher maintenance costs | Similar to Doosan, slightly higher | Similar to Doosan, but pricier |
Key Takeaways from the Comparison:
Engine Power:
Doosan Excavators tend to have higher power at the big end, but don’t be overly concerned about that because most people actually buy the middle of those sizes. Most people don’t buy the big or the small, what they buy is the machine in the middle. Don’t ever let somebody persuade you what you don’t need. If someone says, “I recommend you need this bigger machine,” and you want the big machine, that’s different. But if they say you need a bigger machine to get a sale, run as fast as you can and get away from them. Don’t be pushed into buying a machine you didn’t already have a need for.
Hydraulic Flow:
Doosan Crawlers have equal or more hydraulic flow. They have an average of 600 liters per minute across their pumping system, meaning it can lift, twist, and move 570-720 liters per minute. So, it will lift and lower that much fluid, carry material, or fill a bucket with it. If I want to dig a hole in the ground, it will dig and discharge that fluid when you get rid of it. That’s what we call cycle time. So, you will move a similar or larger volume with these machines than you will with the Komatsu, or the Hitachi, or the Volvo.
Bucket Capacity:
Doosan Excavators average around 1.5 cubic meter buckets from the small 220 to the big 420. By the time you get over that, the buckets start getting huge. But the whole idea is Doosans are going to handle enough to do what they need to do. Again, CAT is a big piece of iron who has big diesel fuel and bigger motors the hydrate that motor burn through fuel and create heat and hydraulic pumps that have to move that oil are expensive. So, CAT makes a big bucket machine to move more dirt, but it will cost more upfront and be more expensive to operate.
Fuel Efficiency:
The people who design and sell Crawler Excavators generally have higher horsepower, higher gallons per hour fuel consumption, and higher price tags upfront. Once you own the machines for a long time, they ALL cost about the same to maintain. Once you own a half a million dollar crawler over five years, they’re all going to be about the same to maintain. When you start comparing, what is my fuel cost? What is my horsepower? That’s where CAT and Hitachi are on the heavy iron that burn a lot of fuel.
Maintenance Costs:
Doosans are as cheap as anything with what we call the wear parts. So, all repair parts are all pretty well priced across the board. Here’s where that pays off: CATs are always going to be a little more expensive for parts. HITACHIs are always going to be a little more expensive for parts.
Conclusion
In summary, Doosan Crawler Excavators are powered, durable, versatile machines capable of delivering the real reliability you need to complete a serious heavy construction project. Combine that with the price, and add in parts and maintenance costs over the life of the machine, and Doosan consistently wins. For people needing a reliable, cost-effective solution to do heavy construction, Doosan Crawler Excavators will provide the horsepower you need. Doosans will provide the reliability you know you need to finish the job. And Doosans will provide the efficiency to keep you from going broke doing so, no matter what it is you are doing.
