Caterpillar CAT320 series excavators have been launched for 50 years. TD details the changes of CAT320 in the past 50 years

     Caterpillar CAT320 series excavators have been around for 50 years since the first generation was launched in 1974. In the past 50 years, Caterpillar CAT320 has been upgraded for more than 10 generations. In the past 50 years, Caterpillar has continuously improved the excavator model, which has left a deep impression on users. The first model we came into contact with when we first entered the industry was the Caterpillar CAT320B. This model was actually older than me when it was launched, but it can still be active on the construction site. However, nowadays, the B and C types are basically no longer seen around us. The reason for the elimination is not the performance, but the equipment cannot be guaranteed for too long and with the increasing requirements for emissions, these equipment can no longer be used normally.

　　However, D-type equipment is still common now. The main reason is that the powerful performance and reliable and stable mechanical quality of this model have conquered users around the world. In 2020. Caterpillar launched the new 320 series, and the sales are still good. However, in the TD used excavator market, CAT320D is still a popular and best-selling model. In 2024. the 20-ton excavator of the excavator trade export, this 320D still sits in the top three, which shows the importance of this model in everyone's mind.

　　1. Caterpillar 320 (1974): As the first model of the Caterpillar 320 series, it was launched on the market in 1974. This excavator adopts the advanced technology and design at that time, and has excellent excavation ability and stability. It is equipped with a diesel engine, which provides powerful power output for the machine and is suitable for various earthwork and stonework projects.

　　2. Caterpillar 320A (1978): In 1978. Caterpillar launched the 320A. Compared with 320.320A, the hydraulic system is optimized to improve the operating efficiency and response speed. In addition, multiple working modes have been added to enable operators to choose the best working method according to different working conditions.

　　3. Caterpillar 320B (1982): Caterpillar launched the 320B in 1982. This generation of models has improved the engine and adopted a more advanced emission control system to reduce noise and fuel consumption. At the same time, a new variable gauge design was introduced to improve the stability and adaptability of the machine.

　　4. Caterpillar 320C (1997): After years of technical accumulation and market research, Caterpillar launched the brand-new 320C series in 1997. This generation of models focuses on operating comfort and safety while maintaining high performance. The cab design is more spacious and bright, equipped with an advanced air conditioning system and shock-absorbing seats. In addition, an electronic control system was introduced to improve the intelligence level of the machine.

　　5. Caterpillar 320D (2003): In 2003. Caterpillar launched the 320D series. This generation of models introduced advanced hydraulic systems and electronic control technologies to achieve higher performance and lower fuel consumption. At the same time, a variety of configuration options are provided, including standard version, long arm version and high flow version, etc., to meet the needs of different customers.

　　6. Caterpillar 320D L (2006): As an extension of the 320D series, Caterpillar launched the 320D L in 2006. This model is mainly designed for customers who need longer booms and sticks to meet special construction needs.

　　7. Caterpillar 320D2 (2011): In 2011. Caterpillar launched the 320D2. This generation of models further optimized the hydraulic system on the basis of 320D, improving work efficiency and ease of operation. At the same time, more advanced engine technology is used to reduce emissions and noise.

　　8. Caterpillar 320D3 (2013): In 2013. Caterpillar released the 320D3. This model uses Caterpillar's "intelligent" hydraulic system to further improve work efficiency and ease of operation. At the same time, the cab has been improved to provide better vision and comfort.

　　9. Caterpillar 320 GC (2018): In order to meet the needs of the small earthmoving engineering market, Caterpillar launched the 320 GC in 2018. This model focuses on fuel economy and ease of maintenance, while maintaining Caterpillar's consistent high performance and reliability.

　　10. Caterpillar 320 (2020 to present): In 2020. Caterpillar released a newly designed 320 excavator. This model incorporates a number of innovative technologies, including a more powerful engine, a more efficient hydraulic system, and a more comfortable cab.

　　With the continuous upgrading of the development of excavators, AI smart or new energy series may replace some urban diesel engine excavators in the future, but diesel as a power output will not be eliminated for some time in the future. The appearance of the Caterpillar 320 series has changed greatly every time it is replaced. Considering the driver's comfort, safety, and intelligent operation to make users more comfortable, if you are a direct user, would you consider Caterpillar?
