Product Description

Built for precision and all-day productivity, this 2014 Caterpillar 312D excavator delivers 72 kW of reliable power through its C4.2 ACERT engine. Operating at 12 tons with a 12,920 kg working weight, this mid-size machine combines robust digging performance with exceptional operator comfort. Equipped with a 0.52 m³ backhoe bucket, it generates 96 kN of bucket digging force and reaches a maximum digging depth of 5,840 mm, handling demanding excavation tasks with confidence.

Operator-focused design ensures superior control and reduced fatigue during extended shifts. The spacious cab provides excellent 360-degree visibility, while intuitive hydraulic controls respond precisely to input. Stable performance comes from a 2,590 mm track gauge and 500 mm-wide track plates, maintaining balance on uneven terrain. The 4.12 MPa pilot oil circuit delivers smooth, responsive movements for fine grading and loading operations.

  • Maximum excavation height: 8,580 mm
  • Maximum reach: 8,430 mm at ground level
  • Travel speeds: 3.4/5.5 km/h for efficient repositioning
  • Water-cooled system with 250 L fuel capacity
  • Currently located in Hangzhou, Zhejiang
