III. Classification, Materials & Manufacturing Process of OEM Buckets

1. OEM Standard Earthmoving Bucket

• Materials: Main body made of Q345B high-strength structural steel; cutting edges and tooth base plates adopt NM360 wear-resistant steel plates.
• Process: CNC flame cutting, fixture positioning and assembly welding, full CO₂ welding for reinforcement, overall shot blasting for rust removal, plus anti-corrosion paint matching Sany’s original color.
• Structure: Wide-opening bucket design with high filling factor and low digging resistance, fitted with standard earthmoving bucket teeth.
• Application: Low-abrasion scenarios including clay excavation, sand handling, river dredging, foundation backfilling and aggregate transportation.

2. OEM Reinforced Rock Bucket (Factory Standard for SY365/SY375)

• Materials: Side and bottom plates thickened by 2–4 mm; tooth bases and side cutting edges made of NM400 wear-resistant steel, with additional wear guards on the bucket bottom.
• Process: Multi-layer surfacing welding on high-stress weld seams, double-arc anti-wear design for bucket bottom, and protective wear strips installed on side edges.
• Application: Medium-impact working conditions such as hard soil, crushed stone, weathered rock, broken muck and small-to-medium quarries.

3. OEM Heavy-Duty Mining Bucket (Exclusive for SY485/SY550)

• Materials: Main body constructed from high-strength H ARD OX wear-resistant steel plates; bucket lugs and connection seats fully thickened, with double-layer wear liners covering the entire bucket bottom.
• Process: Flaw detection implemented on all critical stress-bearing areas; precision boring machining for pin holes. Matched with complete wear-resistant assemblies including forged rock bucket teeth and side guard teeth.
• Application: High-impact, severe abrasion mining scenarios including granite mining, metal ore stripping, hard rock tunneling and heavy rock loading.

IV. Customization Solutions for Custom Buckets

1. Capacity Customization: Narrow trench buckets for ditching, enlarged high-capacity buckets for fast earth loading, wide dredging buckets, trapezoidal grapple buckets.
2. Wear Reinforcement Customization: Overall thickened steel plates, double-layer bottom wear plates, tungsten-carbon alloy surfacing cutting edges, full-coverage side guard plates.
3. Special-Function Bucket Types: Dredging buckets, grid screening buckets, crushing buckets, integrated ripper buckets, inclined ditch buckets, log grapple buckets.
4. Connection Structure Customization: Compatible with quick couplers, extended bucket lugs, adjustable pin center distances to fit modified dipper arms.
5. Matching Wear Parts: Complete customized sets including forged bucket teeth, tooth adapters, wear blades, pins and circlips.

V. Core Advantages of OEM Buckets

1. Precise Original Matching: Strictly replicated from Sany’s original drawings with complete part numbers. Mounting holes are fully aligned, ensuring stable installation without shaking or jamming, and no damage to the excavator’s dipper arm pins.
2. OEM-Grade Materials & Workmanship: High-strength wear-resistant steel dedicated to construction machinery, standardized welding and anti-corrosion coating, delivering far longer service life than ordinary copied buckets with factory warranty standards.
