OEM SHACMAN X3000 M3000 F3000 X6000 Heavy Truck Rear Brake Drum New HD90129340571 Durable Brake Pan Assembly Replacement Parts

Reinforced Z-Shaped Braking Surface with 36 Radial Ribs

⦿ Features a patented thickened Z-profile braking face with 36 uniformly distributed radial ribs to increase structural rigidity and load-bearing surface area. This design minimizes deformation under overloads (up to 105 kg per drum) and prevents stress fractures during aggressive braking.

⦿ User Benefit: 30% longer service life in mining/construction scenarios, reducing downtime and replacement costs.

Advanced Thermal Management Systems

⦿ External Ring Grooves & Ventilated Structures: Rapidly dissipate heat during prolonged braking, lowering surface temperatures by ≥15% and preventing thermal cracks.

⦿ Liquid-Cooled Option (Patented): Sealed fluid reservoir between drum and outer sleeve absorbs friction heat via coolant, reducing failure rates by 30% in mountainous terrains4. User Benefit: Eliminates brake fade during long descents, enhancing safety for fully loaded trucks.

Precision-Engineered Friction Surface

⦿ CNC-machined to DIN Class 5 tolerance (<0.01 mm runout) for even shoe contact, eliminating brake shudder and noise.

⦿ Laser-etched QR codes enable part traceability and maintenance history tracking.

⦿ User Benefit: Smooth, vibration-free braking and simplified maintenance audits.

High-Strength Alloy Construction

⦿ Utilizes Cr/Cu/Mo-modified alloyed cast iron (e.g., HT200 with 0.32% Cr, 0.69% Cu) instead of standard gray iron, offering 2.5× higher wear resistance and 40% extended lifespan in abrasive conditions.

⦿ User Benefit: Withstands gravel-road abrasion in mining operations, cutting part replacement frequency by 25%.

Corrosion-Resistant Surface Treatment

⦿ Zinc-manganese phosphating + matte black epoxy coating (RAL 9005) resists rust and masks oil stains in humid/salty environments.

⦿ User Benefit: Reduced cosmetic degradation in coastal or de-icing chemical-exposed routes.

Mining & Construction Fleets (e.g., Tongli 855, HOWO 70)

⦿ Handles steep descents with overload capacity up to 48% of axle weight without deformation.

⦿ User Impact: 25% lower downtime vs. conventional drums in quarry haulage cycles.

Long-Haul Logistics (e.g., DeLong X3000, SITRAK)

⦿ Plug-and-play compatibility with Shaanxi chassis (e.g., AC26, MCY13), requiring zero modifications and cutting installation time by 50%.

⦿ User Impact: Fleet-wide standardization simplifies inventory and roadside repairs.

Mountainous & High-Heat Regions

⦿ Liquid-cooled variants maintain stable friction coefficients (μ ≥ 0.38) even at 400°C, preventing "brake vanish" during alpine descents.

⦿ User Impact: Eliminates auxiliary spray systems, saving $1,200/year/truck in water/equipment costs.

Aftermarket Service Networks

⦿ Interchangeable with Sinotruk/ Scania drums, reducing inventory complexity.

⦿ User Impact: Workshops cut diagnostic/ repair time by 30% using laser-etched QR codes for part verification.

Anti-Corrosion Coating

⦿ Zinc-Manganese Phosphating Base Layer: Provides rust inhibition in humid/salty environments.

⦿ Matte Black Electrostatic Epoxy Finish (RAL 9005): Masks oil stains, reduces glare during maintenance, and enhances chemical resistance.

Enhanced Braking Efficiency

⦿ Torque Capacity: Supports axle overloads up to 48% of rated weight without deformation (e.g., mining trucks like Tongli 855).

⦿ Stable Friction Coefficient (μ ≥ 0.38): Maintains performance even at 400°C, critical for alpine descents.

Durability in Extreme Conditions

⦿ Abrasion Resistance: Withstands gravel-road wear in mining/construction, reducing replacement frequency by 25%.

⦿ Sealed Bearings: Prevent dust/water ingress in off-road operations.
