Power & Fuel EfficiencyProduct Features & Strengths
CAT C4.4 Efficient Power Unit For CAT 323 excavator
- This 23 ton crawler digger uses original CAT C4.4 diesel engine, reliably starting in cold mountain zones and maintaining steady power for digging and light rock breaking. Optimized fuel injection cuts daily fuel cost versus medium hydraulic excavator with aftermarket engines. Dual-layer air filters block site dust, reduce cylinder wear and prolong overhaul cycles of the CAT medium excavator.
Load-Sensing Hydraulic System & Constant Temperature Cooling Module
- CAT 323 excavator comes with a built-in composite hydraulic radiator, its standout edge against ordinary 23 ton crawler digger. It stabilizes oil temperature during 10+ hours of hot summer work to stop pipe aging and pump damage. Load-sensing valves enable precise digging control for landscaping and bulk earth hauling on this construction crawler excavator. Thick explosion-proof pipelines on the CAT medium excavator prevent hydraulic leakage under medium excavation loads.
Low Ground Pressure Chassis & Lightweight Reinforced Frame
- CAT 323 excavator’s one-piece thick high-tensile steel frame features a 2990mm wide track that distributes weight to avoid sinking on muddy ground. Standard wear-resistant steel track pads suit rough soil and gravel sites for the medium hydraulic excavator. Sealed lubricated rollers cut frequent part replacement of the construction crawler excavator, and retractable tracks narrow the machine for easier highway transport of the CAT medium excavator.
Multi-Attachment Compatibility & Ergonomic Operator Cabin
- Factory multi-way auxiliary hydraulics on CAT 323 excavator allow fast fit of grading buckets, breakers, quick hitches and grapples without refitting. This 23 ton crawler digger switches between digging, crushing and grading in 8 minutes to boost site productivity. Dual ISO/SAE control modes fit global operators of the medium hydraulic excavator, while the air-conditioned shock-absorbing cabin eases all-day shifts of the construction crawler excavator, adapting the CAT medium excavator to city, mountain and coastal building sites.
