Product Description

On site in Sichuan and ready to cut grade, this 2020 Caterpillar 390DL does not need a prep week. Operating weight sits at 90,390 kg across a 3,510 mm track gauge, with 650/750/900 mm shoe options to suit soft clay or rock. A C18 ACERT engine pushes 390 kW into a 995 L hydraulic system, feeding 363 kN of bucket force and 276 kN of stick force — enough to load out rock, trench to 9,660 mm, and swing 4.6 m³ every pass.

  • Maximum digging depth 9,660 mm; vertical wall cut 6,850 mm
  • Ground-level reach 14,690 mm; dump height 9,270 mm
  • Ground pressure 88.3–122.4 kPa for stable footing on soft ground
  • 1,240 L fuel tank keeps long shifts running without refueling stops
  • 4.5 km/h travel and 590 kN tractive force for muddy haul roads
  • 14,700 mm transport length, 4,260 mm width, 5,290 mm height for standard lowboy moves

Bucket, undercarriage, and hydraulics are matched to production work: mass excavation, trenching, site grading, and structural demolition. Inspect it, load it, and start digging.
