  • Operating weight 47 930 - 49 995 kg 105,670 - 110,220 lbs.
  • Bucket capacity 1.12 - 3.17 m³ 1.47 - 4.15 yd³

High production, easily transportable

Built for high production jobs, the PC490LC-11 is a large but portable excavator with a heavy-duty reinforced undercarriage for high lift capacity, lateral stability and added durability.

  • Large high-strength steel castings on the boom, arm and bucket link
  • Closed-center load-sensing hydraulics for precise, fine control
  • Large displacement high-efficiency pumps provide optimal attachment flow
  • Large, spacious, quiet cab featuring standard air suspension seat

Features and benefits

Large displacement high efficiency pump

Large displacement hydraulic implement pumps provide high flow output at lower engine RPM, operation at the most efficient engine speed.

Closed-center load-sensing hydraulic system

Smooth operation, quick cycle times, great multi-function, while lowering fuel consumption from closed-center load-sensing hydraulic system.

Built for strength

Equipment designed for long-term durability with high resistance to bending and torsional stress. Booms and arms are constructed with thick plates of high tensile strength streel and designed with large cross-sectional areas.

Cleaner emissions

A heavy-duty aftertreatment system that combines a Komatsu Diesel Particulate Filter (KDPF) and selective catalytic reduction (SCR). The system injects the correct amount of diesel exhaust fluid at the proper rate, decomposing nitrogen oxide.

Easy access

Engine oil check and filter locations integrated into one side to allow easier maintenance access.

Advanced ergonomic design

Wide spacious cab includes a heated air suspension seat with reclining backrest. Seat height and position are easily adjusted using a pull-up lever. Armrest position easily adjusted with the console.

Information at your fingertips

Updated, large, high-resolution LCD color monitor to ease accurate and smooth work. Key machine information displayed in user-friendly interface, rearview camera and DEF level gauge display added to default main screen.

Rollover protection

A ROPS cab that conforms to ISO 12117-2 comes as standard equipment. It also satisfies requirements for level 1 operator protective guard (OPG) and top guard (ISO 10262).

Multi-operator productivity

An operator identification ID can be set up for each operator and used to manage operation information of individual machines using Komtrax data. Data can analyze operation status by operator and by machine.

Reduce fuel consumption

Auto idle shutdown automatically shuts the engine down after idling for a set period to reduce unnecessary fuel consumption and exhaust emissions. Time before engine is shutdown can be programmed from 5 to 60 minutes.

Designed for durability

Large heavy-duty revolving frame guards and swivel guard help protect vital components from damage and debris build-up.

Ease of maintenance and serviceability

Provide a convenient and more secure work area in front of the engine. A new step provides easier access for filling the AdBlue/DEF tank.
