Double Pitch Conveyor Chain with Attachments
Engineered for efficient material handling in industrial conveyor systems, the Double Pitch Conveyor Chain with Attachments combines the advantages of double pitch design—optimized for low-speed, long-distance conveying—with customizable attachments, delivering reliable performance, flexible adaptability, and reduced operational costs. Adhering to ANSI B29.1 and ISO 606 standards, this chain is tailored for scenarios requiring stable transportation of bulk or unit goods, making it a core component in logistics, manufacturing, and processing industries.
Core Advantages: Double Pitch Design & Versatile Attachments
The defining feature of this chain is its double pitch structure, where the pitch length is twice that of standard roller chains (ranging from 25.4mm to 63.5mm). This design reduces the number of chain links and sprocket teeth required for the same conveying distance, minimizing weight, friction, and wear—directly lowering energy consumption and maintenance frequency. Crafted from high-grade carbon steel (1045) or alloy steel, the chain links undergo precision stamping and heat treatment, ensuring excellent tensile strength and structural stability even under continuous long-distance operation.
Customizable attachments are the key to its versatility, enabling seamless integration with diverse conveying needs. Available attachment types include K1, K2, A1, A2, and custom-designed fixtures, each engineered for specific material handling requirements: K-type attachments for pushing or pulling goods, A-type attachments for supporting or carrying items, and specialized attachments for irregularly shaped products. These attachments are seamlessly welded or bolted to the straight side plates, with strict dimensional tolerances ensuring consistent positioning and stable material transport, eliminating slippage or displacement during operation.
Efficiency and adaptability are further enhanced by optimized structural design. The roller-bushing assembly minimizes contact friction with rails and sprockets, extending service life, while the double pitch structure allows for larger sprockets—reducing rotational speed and noise (operating noise ≤55dB). The chain supports both cottered and spring clip connections for easy on-site assembly, disassembly, and length adjustment, and optional surface treatments (black oxide, zinc plating, hot-dip galvanizing) provide corrosion resistance for use in humid, dusty, or moderately corrosive environments.
Structural Excellence & Operational Resilience
Designed for low-speed, high-capacity conveying (0.1-3m/min), the chain maintains stable performance across long distances and complex layouts—including straight, curved, and inclined paths (maximum climbing angle 25°). Its robust construction withstands static and dynamic loads from bulk materials such as grain, coal, and plastic particles, as well as unit goods like cartons, pallets, and components. The heat-treated rollers and pins (HRC 58-62 surface hardness) resist wear, while the thickened side plates ensure attachment stability and prevent deformation under load.
Safety and maintainability are integrated into the design. The smooth roller surface and rounded attachment edges minimize material damage and debris accumulation, reducing jamming risks. The predictable wear pattern allows for proactive maintenance scheduling, and the standard ANSI dimensions ensure universal compatibility with existing conveyor systems—lowering replacement costs and downtime. Additionally, the chain operates stably in a temperature range of -20℃ to 120℃, adapting to indoor and outdoor industrial environments.
