Three 20-ton medium-sized excavators that are still popular despite being discontinu

​​​​​​​　　Today, TD recommends three medium-sized excavators that are still very popular in the construction machinery industry despite being discontinued. It's not that the new excavators have poor performance, but that these three excavators are more cost-effective. And the performance can still meet the needs of users. The upgrades of the new excavators are now roughly divided into performance upgrades, environmental upgrades, and driving comfort upgrades. In terms of performance alone, the performance improvement of the excavator is actually not large. If it is not a necessary choice, the performance of some old excavators is completely sufficient.

　　Caterpillar CAT series D excavators, Komatsu 7 series excavators, and Hitachi ZX-6 series excavators have all been tested by the market. In the more than ten years of the excavator sales cycle, users have given very good reviews. In particular, this generation of excavators uses direct injection engines. Reliability and low failure rate are both worth considering. Today in 2024. many users still have a very high evaluation of these excavators. Lower prices and reliable performance make it difficult for users not to choose it.

　　Used Caterpillar 320D excavator

　　A classic model produced by Caterpillar has been widely recognized in the market for its durability, powerful power and efficient performance. The following is a detailed introduction to the Caterpillar 320D excavator:

　　Basic information
