CATERPILLAR 323 CRAWLER EXCAVATOR

Technical Description

The Caterpillar 323 hydraulic excavator features a robust C7.1 ACERT engine delivering a net power of 162 hp (121 kW), meeting U.S. EPA Tier 4 Final and EU Stage V emission standards with an advanced aftertreatment system requiring no operator intervention. It has an operating weight of approximately 56,200 lbs (25,500 kg), optimized for medium-scale excavation tasks. The machine is equipped with a heavy-duty 5.7 m (18'8") reach boom and a 2.9 m (9'6") stick, allowing a maximum digging depth of 22.0 ft (6.73 m) and a maximum reach along the ground of 32.1 ft (9.87 m). The hydraulic system supports a high flow of 429 L/min (113 gal/min) at a maximum pressure of 35,000 kPa (5,075 psi), enabling powerful implement operation including a standard 1.30 to 1.38 m³ (1.70 to 1.81 yd³) HD bucket. The excavator’s swing mechanism operates at an 11.25 rpm speed with a maximum swing torque of 82 kN·m (60,300 lb-ft), providing efficient maneuverability. It runs on triple grouser track shoes (typically 790 mm or 31") that offer excellent traction and stability. The machine includes advanced features such as Cat GRADE with Assist, Cat PAYLOAD, remote flash updates, lift assist, and rear and side cameras to enhance precision and operator safety. Its robust build, fuel efficiency, and advanced operator support systems make the Cat 323 suitable for various demanding applications including construction, utility, and pipeline work. The combination of emission compliance, power, range, and technological integration positions the 323 as a versatile and reliable excavator in the medium class.
