In China, Komatsu's eighth generation machine is commonly referred to as-After encountering cold, the 8 series excavator was upgraded. The Komatsu -8MO series now uses the more mature and stable Komatsu SAA6D107E-1 engine in this generation, which has significantly improved fuel consumption compared to the first generation -8 excavator. The power of the engine has also reached 103/2000 (kw/rpm), which can be said that the overall performance of the Komatsu model is average without any particularly eye-catching performance. However, we should know that the biggest advantage of the Komatsu model in front of our owners is stability.
The overall performance of the machine is average, but it is more durable in terms of stability and coordination. The new models are no longer able to last for more than ten years like an old machine used to. The biggest expectation for all machine owners now is to have no major failure rate within six or seven years.MO mainly uses water-cooled 4-stroke, turbocharged, and post cooled main pumps, which also use variable displacement piston pumps. The maximum flow rate of the main pump can reach 439I/min, which is also easy to handle under some suitable working conditions. We are not mainly introducing domestic MO here, but rather the 11th generation equipment and machinery popular in Japan.
The Komatsu we are currently purchasingWe can say that the new model can be seen in the Huacheng second-hand excavator marketKomatsu PC200-10excavating machineryBefore this generation of machines was mass-produced and sold domestically, Japan had already reached KomatsuThe PC200-11 generation excavator can be said to have a very fast update speed in Japan's construction machinery excavators. The technological upgrade is a big step forward compared to the MO series. In terms of engine power, upgrading directly from the current 103kw to 123kw can improve power performance by nearly 20% while reducing fuel consumption by 6%. The overall noise of the engine has also been significantly reduced compared to the previous generation. With the continuous upgrading of environmental protection requirements in China, I think the upgrading of the 11th generation in China is not too far away. In the 11th generation, Komatsu's mining power upgrade has a nearly 8% increase in power compared to the MO series. Further safety upgrades have been made to the structure of the cab. And the whole machine provides a body safety camera projection technology with no dead corners at the left and right rear, which has made significant progress in both operation and safety. The weight of the whole machine is 21200kg, the displacement is 6.69, and the maximum excavation height can reach 10 meters.
In Huacheng's opinion, we need to get startedIt may be difficult to achieve the 10th or 11th generation machines in a short period of time. The Huacheng second-hand excavator market will import them as soon as possible to allow us, the majority of machine owners, to use Japan's most advanced Komatsu PC200-11 machines in advance.
