2023 Komatsu Excavators PC1250SP-11
Ideal for mass excavation jobs, this large excavator comes with a Super Performance arrangement that includes a short undercarriage, short mass excavation boom and larger buckets for high production truck loading.
Features May Include:Powerful engine
- 13% more HP and up to 8% greater productivity*. A Tier 4 Final-compliant engine without requiring diesel exhaust fluid or a selective catalytic converter. Auto idle shutdown timer and thermostatically controlled variable speed cooling fan.
Reinforced structures
- Withstand tough applications with strengthened revolving, center and crawler frames. Large cross-section structures use high-tensile-strength steel to increase durability and resistance to bending and torsional stresses.
Improved serviceability
- Gain easy access to engine, hydraulic system and maintenance service areas with center and large left side walkways. Engine air cleaners have been relocated outside the engine compartment for easy access.
Enhanced cab
- Keep your operators comfortable with a large pressurized cab that comes with a 7-inch color monitor and fully adjustable, heated air-suspension seat. Optional 45° hydraulic access ladder for ease of operator entry and exit.
Enhanced hydraulic system
- Smarter hydraulics with increased flow at higher pressures and new EPC valves improve machine logic to match working loads.* New filter by-pass sensors monitor system health and alert operators if clogging conditions exist.
Improved operator awareness
- Standard KomVision -camera system provides a bird’s-eye view of the surrounding area for improved operator situational awareness.* Komtrax Plus enables expanded monitoring of the fleet via satellite and wireless LAN.
