When your project involves high-abrasion environments like mining, hard rock trenching, or demolition, your bucket is the first line of defense. Engineered to match the power of the excavator CAT336, our 1.8 CBM Heavy-Duty Rock Bucket is designed to maximize productivity while minimizing downtime in the world’s toughest terrains.
Optimized Capacity for 30-36 Ton Class
With a 1.8 m³ (CBM) capacity, this bucket is perfectly balanced for the CAT336 excavator. It provides the ideal volume-to-weight ratio to ensure fast cycle times without overstressing the machine’s hydraulic system, keeping your production on schedule and fuel consumption efficient.
Extreme Wear Protection & Durability
This bucket features a multi-layer protection system:
Reinforced Side Plates & Wear Buttons: The side walls are equipped with high-density wear buttons (chocky bars) to absorb lateral impacts and prevent premature wall thinning in abrasive soil.
Full Side Shrouds: Bolted or welded side shrouds protect the leading edges, ensuring the bucket maintains its integrity even when prying into fractured rock.
Bottom Wear Bands: The external curve of the bucket features heavy-duty wear strips that act as a sacrificial layer, protecting the main structure from constant ground friction.
High-Strength Lip & Teeth: Equipped with five heavy-duty rock teeth and lip shrouds to ensure maximum penetration and material retention.
Technical Specifications
Bucket Type: Heavy-Duty Rock (HD Rock)
Capacity: 1.8 m³ (CBM)
Compatible Machine: CAT336, CAT330, and similar 30-36 ton excavators.

Why Choose Our Rock Bucket?
Mining-Grade Steel: Main body made of NM400 with NM500 reinforced wear parts. Every high-stress point is reinforced with premium wear-resistant steel to withstand high-impact loading.
Precision Engineering: The double-reinforced ear plates ensure a perfect fit for standard CAT336 pins and quick couplers, eliminating “play” and reducing pin wear.
Maximum Penetration: The aggressive profile design reduces drag during the dig cycle, allowing the CAT336 to utilize its full breakout force.
