This 20-year-old Caterpillar 320GC excavator is a very popular medium-sized excavator in the market. It has over 15,000 hours of working time, yet still maintains a good working condition and outstanding performance. This machine is renowned for its outstanding durability and reliability, and is highly suitable for efficient operation in various working conditions. In terms of the power system, this excavator is equipped with an efficient Caterpillar C7.1 inline six-cylinder turbocharged diesel engine, with a maximum output power of up to 140 horsepower (approximately 104 kilowatts). This engine not only offers strong power support but also features excellent fuel economy, enabling it to reduce operating costs while ensuring work efficiency.
