2023 Komatsu Excavators PC390LC-11 SLF
If you need a powerful and stable excavator, but also need a large working envelope, mount a super long front to the PC390LC-10 and you’ll have a machine engineered for the power and reach you need.
Features May Include:Versatile arrangements
- Large selection of ditch-cleaning and general-purpose buckets to meet your job site’s needs. Arm tucks under boom for lowest possible transport height without disassembly.
Durability with reinforced parts
- Hardened steel and nickel plated for corrosion and wear resistance. Cast bucket power link and sealed hardened bushing provide even more durability.
Smooth loading and control
- Smooth bucket control and two return hoses to improve hydraulic performance. During the arm out function, a portion of the oil is returned directly back to the tank for smooth operation.
