Caterpillar has been developing Mini excavators for many years. Currently, there are 11 mini models under 5 tons. Today, Tiedou will introduce four Caterpillar Mini excavators under 2 tons. However, from the comparison of parameters, Mini excavators do not focus on powerful performance. Considering the different design and use environment, Mini excavators pay more attention to the service life and fuel economy of the product. The excavator equipped with Mini has a small power and the fuel tank capacity is usually only 10-30L. Such a small fuel tank can usually be filled up to meet the normal use of the entire working day or even longer. The small fuel tank also means convenient refueling.
Today's four models are all new Caterpillar excavator models. Compared with the previous generation models, there is a significant improvement in engine fuel efficiency, and the response speed and hydraulic flow of the hydraulic pump have also been significantly improved. However, for Mini excavators, a small improvement cannot obviously and intuitively bring about an improvement in work efficiency. But the automatic idling and shutdown functions are very big improvements. Mini excavators, especially small-tonnage excavators, cannot be equipped with a cockpit. Due to space design issues, it is difficult to achieve the same driving comfort as medium and large equipment. Improving seat comfort is also a significant upgrade. Tiedou has used the excavator market. The reference price of Caterpillar CAT series Mini excavators is currently 10.000-20.000 US dollars. The price is mainly for the previous generation of product models, and the new model is more expensive. It is very sufficient for use.

Tiedou introduced many brands and models of Mini excavators. If you want to divide them into detailed performance categories, there is actually not much difference. Whether it is the shape or the work performance, the difference between them is very small. But what we focus on is that service life and stability and reliability are the core technologies. Caterpillar excavator mechanical matching or user feedback information shows that Caterpillar's mechanical quality is very good. Later maintenance is also relatively convenient. Here Tiedou kindly reminds that many niche manufacturers sell excavator equipment through assembly, which is somewhat anti-human in installation and practical design. As a result, later replacement and maintenance are very cumbersome. This is also one of the reasons why we recommend users to buy well-known brands as much as possible.
