2020 Caterpillar 320D

Built around the Caterpillar C6.4 ACERT engine producing 103 kW at 2,000 rpm, the 320D is engineered for sustained output in demanding excavation cycles. Water-cooled across six cylinders with a 6.37L displacement, this powerplant drives a dual-circuit hydraulic system delivering up to 205 L/min from the main pump at 35 MPa working pressure — giving operators consistent force through every dig.

At 20,930 kg operating weight with a 1 m³ backhoe bucket, this 2020 unit from Jiangsu offers precision and raw digging capability in a proven 20-ton platform. Bucket digging force reaches 140.1 kN; arm digging force holds at 106.4 kN — numbers that translate directly to productivity on grade work, trenching, and mass excavation.

• Maximum digging depth: 6,710 mm
• Maximum excavation radius: 9,850 mm
• Maximum excavation height: 9,840 mm
• Travel speed: 3.5 / 5.7 km/h (low/high range)
• Climbing ability: 70% / 35°
• Track plate width: 600 mm | Ground pressure: 6 kPa
• Hydraulic tank: 120 L | Fuel tank: 410 L
• Transport dimensions: 9,460 × 2,800 × 3,050 mm

Manufactured under joint-venture standards with Caterpillar's global engineering specifications, the 320D series carries a reputation for structural reliability and low maintenance intervals — making this unit a sound acquisition for contractors prioritizing uptime over replacement cycles.
