2020 Caterpillar 330B

Engineered for demanding excavation operations, this 2020 Caterpillar 330B delivers exceptional performance through proven hydraulic architecture and robust powertrain design. The Caterpillar 3306TA turbocharged, after-cooled engine generates 165.5 kW at 1,800 rpm, coupled with a high-capacity hydraulic system flowing 480 l/min at 34.3 Mpa—ensuring responsive digging force and precise control across all working conditions.

Operating at 30 tons with a 32,420 kg working weight, this machine combines reach and stability. Maximum digging depth extends to 8,080 mm while excavation radius reaches 11,620 mm, supported by a 1.5 m³ bucket capacity for productive cycle times. The 6,500 mm boom and 3,900 mm arm configuration optimize breakout force and material handling efficiency.

Built on Caterpillar's joint venture/import manufacturing standards, the 330B features water-cooled six-cylinder architecture with 10.5 L displacement. Comprehensive fluid capacities—560 L fuel, 400 L hydraulic system—support extended operational intervals. Currently located in Zhejiang, this unit represents field-proven engineering for contractors requiring reliable production in infrastructure, mining, and heavy civil applications.
