Product Features & Detailed Strengths
CAT C9 High Efficiency Power Unit For CAT 330D excavator
This 30 ton crawler digger uses genuine CAT C9 industrial diesel engine, reliable for cold starts at frigid alpine mines and steady full-load rock breaking. Optimized fuel injection cuts daily fuel cost versus heavy hydraulic excavator with aftermarket engines. Multi-layer air filters block mine dust, lowering cylinder abrasion and extending overhaul intervals for the CAT large crawler excavator.Load-Sensing Hydraulic System & All-Day Cooling Module
CAT 330D excavator comes with an extra-large built-in hydraulic radiator, its standout edge against ordinary 30 ton crawler digger. It keeps hydraulic oil safe even after 10+ hours of 38℃ quarry work, stopping pipe aging and pump damage. Load-sensing valves enable precise digging control for mineral sorting and bulk earth hauling on this mining construction excavator. Thick explosion-proof pipes on the CAT large crawler excavator stop heavy-load hydraulic leakage entirely.Reinforced Wear Resistant Chassis & Heavy Duty Frame
CAT 330D excavator’s one-piece thick high-tensile steel frame features a 3190mm wide track that distributes weight to avoid sinking on muddy mine ground. Standard thick wear-resistant steel track pads fit rocky rough sites for the heavy hydraulic excavator. Sealed lubricated rollers reduce frequent part replacement of the mining construction excavator, and retractable tracks narrow the machine for easier highway transport of the CAT large crawler excavator.Multi-Attachment Matching & Humanized Operation Cabin
Factory-installed multi-way auxiliary hydraulics on CAT 330D excavator allow fast fit of breakers, large buckets, grapples and rippers without refitting. This 30 ton crawler digger switches between crushing, digging and grabbing in 10 minutes to boost mine output. Dual ISO/SAE control modes suit global operators of the heavy hydraulic excavator, while the air-conditioned shock-absorbing cabin eases all-day shifts of the mining construction excavator, adapting the CAT large crawler excavator to desert, mountain and coastal quarries.![CAT 330D.jpg]( "CAT 330D.jpg")
