Chain Specifications

The document lists multiple chain models identified by chain numbers (e.g., LH2066(DG), LL2866(DGF1), LH3288F7(DG), etc.). Each model is characterized by the following parameters:

• Pitch: The distance between chain links, given in millimeters.
• Plate Dimensions: Including plate lacing size (e.g., 4×6, 6×6, 8×8, 10×10), plate thickness, depth, and width.
• Pin Dimensions: Pin diameter and length are specified for each chain type.
• Maximum Dimensions: Maximum allowable values for parameters such as h2 (height), L (length), and d2 (diameter).
• Weight: Weight per meter of chain in kilograms.
• Tensile Strength: Average tensile strength per meter, provided in both kilonewtons (kN) and pounds-force (lbf), indicating the load capacity of the chain.

Key Parameters and Ranges

The chains vary in pitch from approximately 31.75 mm to 63.50 mm. Plate lacing sizes range from 4×4 up to 10×10 mm. Pin diameters range from about 4.8 mm to 9.91 mm. Tensile strengths span from roughly 231 kN (about 52,000 lbf) up to 1735 kN (about 390,000 lbf), reflecting a wide range of load capacities suitable for different sky stacker applications.

Data Tables Summary

The tables provide a matrix of chain numbers against their physical and mechanical properties. For example:

• Chain LH2066(DG): Pitch 31.75 mm, plate lacing 6×6, pin diameter 4.8 mm, tensile strength approx. 347 kN (78,000 lbf), weight 11.65 kg/m.
• Chain LH3288F7(DG): Pitch 50.80 mm, plate lacing 8×8, pin diameter 7.2 mm, tensile strength approx. 1513 kN (340,000 lbf), weight 35.19 kg/m.
• Chain LL4066F5(DG): Pitch 63.50 mm, plate lacing 8×8, pin diameter 8.0 mm, tensile strength approx. 1080 kN (243,000 lbf), weight 32.59 kg/m.

Applications and Recommendations

These leaf chains are designed specifically for sky stackers, which require high tensile strength and durability. Selection of the appropriate chain model should consider the required load capacity, dimensional constraints, and environmental conditions.

Critical Information and Best Practices

• Ensure chain selection matches or exceeds the maximum expected tensile load to maintain safety and performance.
• Verify dimensional compatibility with the sky stacker mechanism, especially pitch and pin dimensions.
• Consider weight implications for system design and handling.
• Consult manufacturer for custom requirements or further technical support.
