| About EL(LL) Series Leaf Chain
EL (LL) series leaf chains made to ISO standards are constructed of plates and pin diameter similar to British standard roller chains of same pitch.
For example, EL6 (LL12) uses plates and pin diameter of BS 12B roller chain.
EL leaf chains are commonly used for lightweight load equipment and light lifting applications.
For corrosive environment, CRF corrosion resistant coating is available.
For heavy duty applications, BL series leaf chains are recommended.
| Features
- Heat treatment for improved hardness and strength
- Shot peening for improved fatigue strength
- Pre-stretched to minimize initial stretch
- Pre-lubricated from the factory
- Corrosion resistant coating available
| How to select leaf chain for your application
1. Determine the type of leaf chains and service factor from below application table.
| Shock Load | Application | Chain Type | Chain Speed | Service Factor |
Smooth Running | Smooth start & stop Slow operating Gentle vibration | EL Series | Less than 100 ft. / min. | 1.0 |
Moderate Shock | Frequent start & stop Constant variation of load Reverse operating | BL Series | 1.3 | |
Heavy Shock | Sudden start & stop Constant variation of load Reverse operating | BL Series | 1.5 |
2. Multiply required working load of your lead chain by above service factor and below safety factor to obtain the tensile strength.
| Chain Type | Chain Speed | Max. numbers of Reciprocation | Safety Factor |
| EL Series | Less than 100 ft. / min. | Less than 100 times per day | 12 |
| BL Series | Less than 100 ft. / min. | Less than 1000 times per day | 9 |
3. Select proper leaf chain with the minimum tensile strength above the value obtained in step 2.
Working Load x Service Factor x Safety Factor ≥ Leaf Chain with Minimum Tensile Strength
Working load includes attachments weight, inertia force, and impact force.
