Types of Chain Connectors
1. Quick Links
Quick links are versatile connectors that allow quick and easy connections between chains and accessories. They are commonly used in various applications, including towing and rigging. The primary advantage of quick links is their ease of use—operators can quickly disconnect and reconnect as needed.
2. Coupling Links
Coupling links are essential in rigging applications, enabling seamless connections between different chain sections or accessories. They are available in various grades, with Grade 80, 100, and 120 being the most common. Each grade has a distinct load capacity and application suitability, making it crucial to select the right type for your project.
3. Hammerlok Coupling Links
Designed specifically for overhead lifting, Hammerlok coupling links are robust and reliable connectors. They are often used in lifting slings to connect the legs of the sling to a master link or hook attachment. These links are engineered to withstand the high demands of lifting operations, ensuring safety and reliability.
4. Weblok
Weblok connectors are specialized coupling links designed for synthetic sling construction. They feature one round and one flat bearing surface, allowing for a secure connection with synthetic materials. Webloks are particularly useful in applications where flexibility and strength are required.
5. Double Clevis Links
Double clevis links provide a secure connection point for two chains or accessories. They are commonly used in multi-point rigging setups, allowing operators to connect multiple components efficiently. The design of double clevis links ensures a reliable connection while maintaining the integrity of the rigging system.
