Wide Welded Steel WD480 Chain | DCC
DCC WD480 Chain is a heavy-duty welded steel drag chain optimized for large-scale bulk material handling in demanding drag conveyor systems. Featuring a 203.2mm pitch and expansive 285.75mm inner width, it facilitates high-capacity transport of heavy materials like coal, aggregates, or biomass at 27kg/m. Offered in WDH480 (360KN tensile strength) for extreme loads and WDR480 (310KN) for robust standard use, it delivers dependable performance in abrasive, high-volume environments.

Key Features of DCC WD480 Chain
● Expansive Width Configuration: 285.75mm inner width and 323.85mm outer width create a broad pushing surface for superior material containment, minimizing overflow and supporting efficient conveyance of bulky loads at controlled speeds.
● Reinforced Sidebar Build: 50.8mm sidebar height combined with 12.7mm thickness provides exceptional structural integrity for sustained heavy-duty operation under significant stress.
● Sturdy Pin and Bushing Assembly: 22.07mm pin diameter with A-sized bushing ensures reliable pivoting and enhanced wear resistance in tough, particle-laden settings.
● Precision Welded Fabrication: Automated robotic welding guarantees consistent weld quality, boosting chain durability and resistance to fatigue over extended cycles.
● Advanced Wear Resistance: High-frequency heat treatment on critical parts preserves chain integrity in gritty conditions, prolonging service intervals.
● Protective Surface Treatment: Galvanization or specialized coating shields against corrosion from moisture and mild corrosives, ideal for challenging indoor or covered outdoor applications.

FAQ
Q: How does WD480 differ from WD110 or similar chains?
A: WD480 features a wider 285.75mm inner section and higher strengths (up to 360KN) for heavier bulk loads, unlike narrower WD110 suited for lighter volumes.
Q: What loads can the tensile strength support safely?
A: Applying standard safety factors, WDH480 handles extensive continuous loads in drag systems; WDR480 fits moderate heavy applications.
Q: What lubrication intervals apply to WD480?
A: Enhanced coatings permit longer intervals than basic chains, varying by usage environment.
