PC390LCi-11

  • Horsepower 192 kW @ 1 950 rpm 257 HP @ 1,950 rpm
  • Operating weight 39 856 - 41 023 kg 87,867 - 90,441 lbs.
  • Bucket capacity 0.68 - 2.22 m³ 0.89 - 2.91 yd³

Enhanced stability for demanding jobs

When extra stability is needed, the PC390LCi-11 blends performance with intelligent machine control. This machine provides up to 18% greater lift capacity* over the side and comes with a factory 3D GNSS machine control for further capability and performance.
* compared to PC360LCi-11

Features and benefits

Adjusts to the operator’s experience level

A fully integrated grade assist automatically traces the target surface to minimize over digging. A built-in facing angle compass ensures the machine is aligned with the target surface.

Auto stop control

To help eliminate potential damage during boom or bucket operation, the machine automatically stops when the bucket edge reaches the design surface.

Minimum distance control

iMC controls the bucket by automatically selecting the point closest to the target surface, which minimizes operator input while providing higher accuracy and grading confidence.

Critical precision for utility applications

For utility customers looking for the utmost precision, the excavator allows your operator to input structure, invert elevations of pipe runs and automatically calculates fall of pipe.

Powerful, advanced engine

Your fleet can be environmentally friendly without sacrificing power. Excavators with iMC 1.0 are equipment with a Tier 4 Final certified Komatsu SAA6D107E-3 engine, which features an integrated diesel particulate filter, hydraulically actuated Komatsu variable geometry turbocharger and selective Ccatalytic reduction system.

Stroke sensing hydraulic cylinder

Stroke sensing hydraulic cylinders provide real-time position that is immediately displayed to the operator. This is an improvement over conventional aftermarket machine guidance (indicate only) systems with tilt sensors that require time to stabilize.

Robust undercarriage

A large counterweight and robust undercarriage components help provide outstanding stability.
