LL & EL Series Leaf Chains – High-Strength Leaf Chain for Lifting Applications

Discover premium Leaf Chain solutions fit for safe, dependable and heavy duty lifting applications. LL and EL Leaf Chains Products for UK & International Delivery at Bolton Engineering. At Bolton Engineering we provide LL and EL range leaf chains that are built to last, strong and deliver accurate performance in tough industrial conditions.

Used with leaf chain sprockets, these chains are designed for applications requiring great tensile strength and safety measures rather than high speed — a reliable choice in vertical lifting and load-holding systems.

What Is a Leaf Chain?

A leaf chain is a high-strength, roller-less chain constructed from interlaced steel plates and pins.

Unlike roller chains, leaf chains are designed primarily for tensile load lifting rather than power transmission.

They are most often used in:

• Forklift masts
• Hoists
• Cranes
• Elevators
• Lifting and counterweight systems

LL vs EL Series Leaf Chains

LL Series Leaf Chain

• Based on American (ANSI) standards
• Designed for heavy-duty lifting
• High tensile strength
• Common in forklifts and industrial lifting systems

EL Series Leaf Chain 

• Based on European (ISO/DIN) standards
• Optimized plate geometry for uniform load distribution
• Excellent fatigue resistance
• Widely used in material handling and lifting equipment

Both series are engineered for safety-critical lifting applications.

Key Benefits of LL & EL Leaf Chains

• Extremely high tensile strength
• Excellent resistance to shock loads
• Designed for vertical lifting and load holding
• Long service life under repeated stress
• Manufactured from hardened, high-quality steel
• Compatible with leaf chain sprockets
• Low stretch for precise load control

These features make leaf chains essential in lifting systems where failure is not an option.

Applications of Leaf Chains

Our leaf chains are widely used across industries including:

• Forklift trucks
• Cranes and hoists
• Elevators and lifting platforms
• Material handling equipment
• Construction machinery
• Mining and heavy industrial systems
• Counterweight and balancing mechanisms

They are specifically designed for non-rotational, high-load lifting environments.

Leaf Chain Sprockets Compatibility 

Leaf chains operate with leaf chain sprockets, which differ from standard roller chain sprockets.

These sprockets are designed to engage chain plates directly, ensuring:

• Secure chain seating
• Even load distribution
• Reduced wear on plates and pins
• Correct sprocket selection is essential for safe and efficient operation.

How to Select the Right Leaf Chain

Choosing the correct chain ensures safety and long service life.

1. Identify Chain Series

LL Series → ANSI-based systems

EL Series → ISO/DIN-based systems

2. Confirm Load Requirements

Check:

Working load

Safety factor

Maximum lifting capacity

3. Match Sprocket Type

Always use compatible leaf chain sprockets.

4. Review Duty Cycle

Leaf chains are ideal for:

Repeated lifting

Static load holding

Intermittent motion systems

If unsure, our technical team can help you select the correct chain.

Frequently Asked Questions (FAQs)

1. What is a leaf chain used for?

Leaf chains are used for lifting, hoisting, and load-holding applications rather than power transmission.

2. What is the difference between EL chain and LL chain?

LL chains follow ANSI standards, while EL chains follow European ISO/DIN standards.

3. Can leaf chains be used with standard sprockets?

No. Leaf chains must be used with leaf chain sprockets designed for plate engagement.

4. Are leaf chains suitable for continuous rotation?

No. They are designed for lifting and static load applications, not continuous rotational drives.
