Tiedou's Recommended Excavators (Issue 18) Caterpillar's 4 Medium 20-30 Ton Excavators Recommended

　　Conventional power crawler excavators are still the mainstream models. Currently, many excavator manufacturers have launched hybrid or pure electric power excavators, and the scope of use and performance are still limited and insufficient compared to conventional power. Which of the four medium excavators recommended by Tiedou today do you like? Caterpillar CAT320 is divided into conventional version and GC version. Perhaps many people don't know much about the two excavators. The size specifications of the two versions of 320 are basically the same. Including the engine and hydraulic pump are the same, but the two are very different. In order to meet different work needs, the size adopts the same specifications, but it can be seen from the performance parameters that the engine power of the GC 320 is only 146 horsepower, while the conventional version reaches 162 horsepower. The main reason is that GC is more suitable for work performance requirements that are not high, and the fuel economy is better. The conventional CAT320 has a higher configuration and is suitable for use in environments with high technical requirements and harsh working environments. The prices of these two devices are quite different, and users need to choose to buy according to their own requirements.

　　The size specifications of Caterpillar CAT323 series, 325 series and 326 series are quite different from 320. Although they are equipped with Cat C7.1 ACERT engine, the maximum power of the engine is very different. The maximum difference of hydraulic pump flow is close to 20%. This also means that the larger the model, the stronger the performance, but the difference between these three models in length, width and height is relatively small, mainly for different types of engineering needs. In addition to these models, Caterpillar's previous generation of products also has a very detailed division of models. In terms of price, although the previous generation of products is slightly lower than the new model in technical configuration, the price is lower. Low cost of entry also means higher returns.Tiedou excavator

　　The five Caterpillar medium-sized excavators introduced today are very popular models in the market. Many users prefer the 320GC model in addition to its more favorable price and lower fuel consumption. Whether it is the needs of urban construction or engineering construction, 320GC can fully meet the needs. If you consider the type of project and the complexity of the environment, as well as working in rocks or other types of work with higher performance requirements, Tiedou recommends choosing CAT330 or above excavators to improve efficiency. In the next issue, we will introduce you to the mainstream Caterpillar excavators above 30 tons and their technical features.
