Wide Welded Steel WD113 Chain | DCC
DCC WD113 Chain is a durable welded steel drag chain tailored for efficient bulk material handling in drag conveyor systems. Featuring a 152.4mm pitch and 228.6mm inner width, it facilitates smooth transport of materials like sawdust, grains, or light aggregates at 16.6kg/m. Available in WDH113 (203KN tensile strength) for enhanced load capacity and WDR113 (165KN) for standard duties, it provides reliable operation in moderately abrasive environments.
Key Features of DCC WD113 Chain
● Optimized Width Design: 228.6mm inner width and 269.88mm outer width deliver effective material engagement, minimizing spillage and supporting consistent conveyance of moderate bulk loads at controlled speeds.
● Rigid Sidebar Framework: 38.1mm sidebar height with 12.7mm thickness offers solid support and resistance to deformation under operational stresses.
● Sturdy Pin and Bushing System: 22.07mm pin diameter with C-sized bushing ensures fluid articulation and improved wear tolerance in environments with particulate matter.
● High-Quality Welded Assembly: Automated robotic welding achieves uniform joint strength, increasing overall chain resilience and fatigue life.
● Effective Wear Safeguards: High-frequency heat treatment on key elements maintains structural integrity in abrasive conditions, reducing replacement frequency.
● Surface Corrosion Protection: Galvanization or coating treatment resists moisture and mild corrosives, fitting for indoor or semi-protected applications.
