Product Description
The modern 275-9T excavator, equipped with a gun but no bucket, is priced at over 80,000 yuan. This device features outstanding performance and excellent durability, making it a reliable assistant in your construction projects. The estimated working time is approximately 3,000 hours, which means it is in the golden stage of the mechanical life cycle. It not only ensures sufficient usage experience but also reserves a sufficient service life. In terms of power, this excavator is equipped with a high-performance diesel engine (the specific model may be Cummins or equivalent), providing strong power output with a maximum power of up to 140 kilowatts, ensuring efficient operation under various complex working conditions. Advanced fuel injection technology and cooling system design not only enhance fuel efficiency but also effectively reduce operating costs and maintenance expenses. The hydraulic system adopts the industry-leading combination of variable piston pumps and gear motors, featuring fast response speed, high control accuracy and strong stability. This enables operators to easily handle fine excavation tasks while also meeting the demands of heavy-load operations. In addition, the meticulously tuned rotary mechanism and smooth w
