Six Core Product Advantages
CAT 336GC Hydraulic ExcavatorFuel-Saving Cat C7.1 Engine
The proven C7.1 engine delivers 212 HP with 12% lower fuel consumption than previous models. It provides strong low-speed torque for heavy digging, while the maintenance-free aftertreatment system ensures reliable, cost-effective operation.
High-Efficiency Load-Sensing Hydraulics
Advanced load-sensing system with dual variable pumps optimizes power distribution, ensuring fast, smooth compound actions. Precise pilot controls reduce operator fatigue and improve grading/ trenching accuracy.
Durable Heavy-Duty Construction
Reinforced X-frame, thickened boom/arm and high-strength wear-resistant steel components withstand tough jobsites. The heavy-duty undercarriage resists abrasion and impact, extending service life.
Comfortable & Safe Operation
Spacious ROPS-certified cab reduces noise and vibration. Adjustable seat, intuitive controls and automatic climate control enable all-day comfort, while large windows enhance safety with 360° visibility.
Low Maintenance & Reduced Downtime
Extended, synchronized maintenance intervals cut service costs by up to 20%. Ground-level access to key components simplifies daily checks, and globally available Cat parts minimize repair delays.
Versatile for General Applications
Optimized for general construction, the 330GC excels in earthmoving, road repair, foundation digging and utility projects. A wide range of Cat attachments (buckets, hammers, augers) enhances jobsite flexibility.
