CATERPILLAR 320C LU CRAWLER EXCAVATORS

Technical Description

The Caterpillar 320C LU hydraulic excavator is a versatile machine engineered for efficiency and performance in tight spaces due to its reduced tail swing radius of 6.6 ft, compared to standard models, without compromising stability thanks to a counterweight approximately 70% heavier than the 320C L. It is powered by a robust Cat 3066T diesel engine with a displacement of 389 cubic inches, delivering a gross power of 143 horsepower (107 kW) and net power of 138 horsepower (103 kW). This engine meets US Tier 2 and EU Stage II emissions standards, ensuring compliance with environmental regulations while maintaining strong performance. The excavator offers a maximum digging depth and reach of 25 feet, with a ground clearance of 1.6 feet and a cab height of 9.7 feet, while the width across the outside of the tracks measures 32 feet, providing a solid footprint for stability. The hydraulic system is designed for high efficiency, featuring a main implement flow rate of 205 liters per minute and a pilot system flow of 41 liters per minute, supporting precise control of the boom and stick cylinders. The swing mechanism operates at 11.5 rpm with a swing torque of 61.8 kN·m, enabling smooth and controlled operation. The undercarriage delivers a drawbar pull of 44,040 lbs, with a maximum travel speed of 3.4 mph (5 kph), suitable for maneuvering on various job sites. Fuel capacity is 75 gallons, and hydraulic system fluid capacity is 37 gallons, allowing extended operational periods between refueling and servicing. The machine supports various attachments, including powerful demolition shears and vibratory plate compactors, making it well-suited for earthmoving, demolition, and material handling tasks.
