ANSI AL Series Leaf Chains – Strong & Trusted Load-Bearing Chains

Discover the durability and precision of ANSI AL Series Leaf Chains, purpose-built for lifting and balancing applications. At Bolton Engineering Products Ltd, we offer a wide range of leaf chains, leaf chain assemblies, and matching leaf chain anchor bolts, trusted across industries for high-performance reliability.

These chains consist solely of link plates and pins—no rollers—delivering exceptional tensile strength and compact design, making them a top choice for rugged applications. 

What Makes ANSI AL Series Leaf Chains Special?

• Light-duty yet robust: Designed for compact applications like forklifts, lift trucks, and elevator masts—balancing space constraints with high tensile capacity. 
• Superior construction: Fabricated from hardened, shot-peened materials using ANSI G8 components, ensuring longevity and load consistency. 
• Compact, efficient design: They run over sheaves rather than sprockets, enabling smoother, quieter motion transfer compared to roller chain applications. 

Key Benefits & Applications

• Lifting & balancing: Commonly used in forklift masts and hoist systems. 
• Space-efficient operation: Ideal where compact drive systems are required.
• High tensile strength: A lightweight alternative to traditional roller chains.
• Custom assemblies available: Chain constructed as per application specifications with optional anchor bolt integration. 

Chain Numbering & Specifications

ANSI AL chain sizing follows a structured system: the first digits indicate pitch (in 1/8"), while the latter digits represent plate counts. For example, AL322 translates to a ⅜" pitch with 2×2 link pattern. 

Our product range includes popular variants like AL322, AL544, AL666, and beyond—each offering defined tensile strength, plate thickness, and pin dimensions to match your engineering needs. 

ANSI AL Series vs. BL Series Leaf Chains

• AL Series: Compact, lighter-duty ANSI chains—well-suited to space-sensitive lift systems.
• BL Series: Today’s ANSI standard—built with thicker link plates and larger pins for higher tensile strength and rugged performance.

Frequently Asked Questions (FAQs)

Q1. What are ANSI AL Series leaf chains used for?

They’re commonly used in forklift masts, lifting platforms, and balancing systems where compact, high-strength load handling is critical. 

Q2. How do I interpret the leaf chain part numbering?

Example: AL544 means an AL Series chain with ⅝″ pitch (544 = 5 * 1/8″) and a 4×4 plate configuration. 

Q3. What is a leaf chain anchor bolt?

It connects the chain to forklift masts or support structures, providing secure fastening for lifting loads.
