Different changes after the upgrade of Caterpillar 320 series excavators

　　Today, we are talking about Caterpillar CAT320 series excavators, introducing 5 generations of Caterpillar series excavators of different years. Of course, there are also very old models such as V-type V2. which we will not introduce one by one. Occasionally, one or two B-type and C-type excavators with good performance will be seen in the used excavator market. But as time goes by, these models will disappear from our sight in a few years. But every generation of Caterpillar models can bring us great surprises. The oldest models of CAT320B and CAT320C are more than 30 years old, but they can still be seen working in some countries and regions.

　　The ultra-long service life and durable mechanical quality make Caterpillar popular with users in various countries around the world. Especially in the details, Caterpillar is very meticulous. Buy different excavators and disassemble them for comparison. You will find that the details that we cannot see with our naked eyes are still meticulous and difficult to find faults. Especially the perfect adaptability of Caterpillar excavators in different working environments, compared with any brand, the working performance of Caterpillar excavators is the first echelon.
