2023 Komatsu Excavators PC390LC-11 MH
When you require long reach and high stability to handle bulk material with grapples or clams, the PC390LC-11 material handler has the boom and arm combinations you’ll need.
Features May Include:Reinforced design
- Maximize strength and durability while minimizing weight with reinforced box section design using high-strength alloy steel.
Optimized hydraulic system
- Boom and arm cylinders are hydraulically cushioned with spherical ball bushings to eliminate side stress. Optimized hydraulic system fine tunes control functions for smooth machine response.
Designed with safety in mind
- Improve visibility with a high cab riser package. Large slip-resistant platforms with steps and handrails for easy cab access.
