Tiedou's used excavator recommendation (Issue 9) Sany 135. Sany 155. Sany 195 excavators, performance parameters and specifications

​​​​​​​　　As the three main models of Sany, the 135 series, 155 series, and 195 series have undergone many modifications and upgrades, and their appearance has changed slightly from the previous generation. This upgrade is mainly in power upgrade and environmental emission upgrade, especially equipped with Isuzu's new environmentally friendly engine. In addition to reducing emission pollution, the performance in actual use has also been significantly improved. However, the fuel consumption has also been improved to a certain extent compared with the previous generation. But compared with the new model with the same performance output, there is still a significant improvement.

　　This generation has a very obvious improvement in the driving comfort of the excavator and the redesign of the interior of the cab compared with the previous generation. In addition to the Sany 135 series, there is also a model that can replace the Sany 125. However, the size and specifications of the two excavators are not much different, and there are certain differences in the main engine performance output and power. If the user has requirements for fuel economy, choosing the 125 series is also a very good choice. The Sany 155C also has a 155U short-tail excavator, but the number is small, and there are few such models in the Tiedou used excavator market. I won't introduce it in detail here. The Sany 195 is basically in the same echelon as the Sany 205 and 215 series. There is not much difference in size specifications. The Sany 195 excavator has made a little sacrifice in performance and peak power in order to save fuel. But it is still very easy for most jobs. Mainly due to the powerful performance power of the new engine, it can basically reach the same level as the previous generation 215 series.
