The Caterpillar 355 Excavator stands as a powerhouse in large-scale mining and heavy construction operations, engineered to deliver exceptional performance, durability, and efficiency in the most demanding working environments. As a flagship model in Caterpillar’s premium excavator lineup, the 355 combines advanced technology with rugged construction to meet the rigorous demands of large mining operations, heavy construction projects, and major infrastructure developments worldwide.
Powered by the cutting-edge Cat C13B ACERT™ engine, the 355 generates an impressive 354 kW of net power while adhering to strict global emission standards, including EU Stage V and U.S. EPA Tier 4 Final. This high-performance engine, paired with a state-of-the-art hydraulic system featuring adaptive flow technology, delivers superior digging force and lifting capacity while optimizing fuel efficiency—reducing operational costs by up to 30% compared to previous models. With an operating weight of 54,800 kg, the 355 provides exceptional stability even when handling heavy loads in the most challenging terrain, from rugged mining sites to large-scale earthmoving projects.
Operator productivity and comfort are central to the 355’s design, featuring a spacious, climate-controlled cab with industry-leading visibility, low noise levels (63 dB(A) operating sound), and intuitive controls that minimize fatigue during extended shifts. Integrated technology enhances operational efficiency, including Cat Link telematics for real-time machine monitoring, remote diagnostics, and predictive maintenance alerts. Whether deployed in large-scale mining operations, heavy construction, or major infrastructure projects, the Caterpillar 355 Excavator sets new standards for performance, reliability, and cost-effectiveness in the large excavator category.
