Kobelco excavators have always been a popular consulting model in the construction machinery industry, especially after the current Kobelco has been upgraded, the performance has been significantly improved, and most of the excavators of Kobelco, which have always used Hino engines, now use Isuzu engines. Why Kobelco wants to change the engine is mainly because Isuzu engines have a very mature coverage rate in the field of excavators and use and maintenance technology. It is not that the performance of Hino engines is not good, but that the convenience of later maintenance in more countries is considered. This may also be a compromise to cater to the world's construction machinery market.
Although the new excavators use many leading technologies, for some countries, if there is a problem, the maintenance cycle may be very long. Especially in the work site far away from the city, the problem is more obvious. Here I have to say that in the market where excavators have been used, some old excavators with mature technology are loved. The old models are not eliminated. More than 80% of the world is still in use. For excavators over 5 years old, in addition to considering the purchase cost, stable technology is the choice recognized by everyone.
Kobelco second-hand excavators have launched a number of new models after 2020. which have been improved in performance, environmental protection and ease of operation. Here is a detailed introduction to some of the new Kobelco excavators and a comparison with the old models:
SK520LC-11E
- Model: SK520LC-11E
- Specific parameters: 53 tons, Isuzu engine, improved bucket and boom working force, and overall lifting performance.
- Compared with the old model: heavier than the previous generation SK500-11. providing better stability and improved working force.
SK380SRLC-7
- Model: SK380SRLC-7
- Specific parameters: 6% power increase, equipped with 210 kW Isuzu engine, DPF replacement interval extended to 8.000 hours.
- Compared with the old model: replaced the previous 380SRLC model, with increased power, extended DPF replacement interval, and improved maintenance convenience.
SK350DLC-11E
- Model: SK350DLC-11E
- Specific parameters: The engine was changed from Hino to Isuzu, which improved fuel efficiency and performance.
- Compared with the old model: the engine is replaced with Isuzu, which provides better fuel economy and performance.
SK60-10
- Model: SK60-10
- Specific parameters: the cross-section of the big arm is strengthened, the durability is increased by 34%, the Yanmar engine has a power of up to 35.5KW, meets the environmental emission standards of various countries, and the bucket digging force is increased to 40.5KN.
- Compared with the old model: compared with the SK60-8. the SK60-10 has been improved in structural strengthening, durability, operating capacity, and operating performance.
SK200 SuperX and SK210LC SuperX
- Model: SK200 SuperX, SK210LC SuperX
- Specific parameters: improved operating efficiency, low fuel consumption, high durability, and humanized design.
- Compared with the old model: compared with the previous generation, these two models have improved in excavation speed and power, while maintaining low fuel consumption and high durability.
SK140SRLC-7
- Model: SK140SRLC-7
- Specific parameters: Equipped with Isuzu 4HK1X engine, rated power 96kW, working mass 13.8t, standard bucket capacity 0.63m³.
- Compared with the old model: Compared with the previous generation, SK140SRLC-7 has improved in power performance and stability, and meets the environmental emission standards of various countries.
SK75-10
- Model: SK75-10
- Specific parameters: Using Yanmar 4TNV98C engine, meeting the National IV emission standard, working mass 7.4t, standard bucket capacity 0.32m³.
- Compared with the old model: Compared with SK75-8. SK75-10 has improved in power performance and environmental protection, while maintaining a smaller body size, suitable for small space operations.
I don't know if you have noticed that Kobelco's technology in the design and use of short-tail excavators is very mature and popular. After the upgrade, the performance has been significantly upgraded, although it cannot be compared with conventional design excavators. But in special working environments, short-tail excavators are irreplaceable.
