Heavy Duty Buckets are engineered for excavators working in demanding conditions — hard soil, mixed rock, blasting, quarrying, and heavy loading. At YF Bucket, our heavy duty line (HD & HDRC) features thicker wear plates, reinforced cutting edges, and premium steel (Q345, NM400, HARDOX400 etc.) to deliver long service life under harsh environments.
High-strength and wear-resistant steel materials: Q345, NM400, HARDOX400, etc.
Reinforced design with extra braces, side protectors, and robust welding.
Range of volumes/types: suited for mid-to large excavators (3-10m³+).
Customization available: bucket shape, cutting edge, adapter/pin types, matching excavator models.
Global export experience and quality control at every stage.

HD is heavy duty steel for hard soil & mixed rock; HDRC combines high wear steels (NM400 / HARDOX400) with reinforced design for rock & blasting environments.
Match the bucket volume & width to your excavator’s breakout force and hydraulic power. Too large = lowered performance; too small = inefficiency.
Yes — most of our HD / HDRC buckets are designed with replaceable edges or armor for easier maintenance.
