Product Features & Strengths
Original CAT High-Efficiency Diesel Power System
- This CAT 320D excavator uses genuine CAT C6.4 diesel engine with stable startup, low emissions and low fuel consumption. The heavy hydraulic excavator keeps constant power under heavy long-time digging, cutting breakdown risks on muddy mine sites. Its multi-stage filter blocks dust, lengthening maintenance intervals and slashing long-run operating costs for engineering teams with 10+ hour daily shifts.
Mature Reinforced Hydraulic System Assembly
- Unlike cheap refitted construction excavator, this CAT 320D crawler excavator adopts full original CAT hydraulic pump, valve and cylinder. High flow hydraulic parts boost digging and lifting speed. Independent cooling pipelines stop oil overheating in hot tropical areas, while premium sealing eliminates oil leaks and lowers daily maintenance fees for global buyers.
Reinforced Wear-Resistant Working Device
- This CAT digger’s boom, arm and bucket are thick wear-resistant steel with reinforced welding on stress points. The standard 0.92m³ bucket lifts more material per cycle. Swapable bucket teeth avoid full bucket replacement to cut spare part spending. This CAT 320D excavator outlasts generic construction excavator for hard rock mining and high-abrasion jobs.
Shock-Absorbing Spacious Operator Cab
- The CAT 320D crawler excavator’s full suspension cab dampens digging vibration. Panoramic glass delivers 360° sightlines to avoid construction blind spots. Ergonomic joysticks and dashboards let new operators get skilled quickly. Dustproof sound insulation lessens site noise and dust, boosting comfort for all-day shifts on mine and road projects.
Heavy-Duty Anti-Corrosion Crawler Chassis
- This heavy hydraulic excavator features thick alloy track frames, thick shoes and reinforced links for great wear and slip resistance. 35° gradeability lets it traverse muddy hills and uneven mine ground. Integrated anti-rust paint stops corrosion from mud and rain, extending the crawler excavator’s chassis lifespan in humid regions.
Product Application Scenarios
Urban infrastructure construction: Road foundation excavation, municipal pipeline burial, bridge pier foundation digging, sidewalk renovation and urban waste clearance. The stable power of this CAT digger improves construction progress for large municipal projects.
Open-pit mine & quarry work: Ore stripping, rock excavation, mine material loading, slope trimming. The reinforced working device of this CAT 320D excavator adapts to high-abrasion mine operation environment.
Water conservancy engineering: River dredging, reservoir foundation excavation, channel trenching, flood control dike construction. The strong digging force of the crawler excavator handles wet silt and hard soil efficiently.
