Slings and their matching shackles must have matched load capacities. Only when used as a complete set can they meet compliance and safety requirements.
Two-Leg Sling + Matching Shackles
Advantages: Lightweight structure, quick assembly and disassembly, uniform load on two points. When paired with shackles of identical load rating, it delivers reliable connection and high operational efficiency.
Four-Leg Sling + Matching Shackles
Advantages: Load distributed across four points, preventing the lifted load from tilting or overturning. The complete set is fitted with dedicated shackles of consistent load capacity to effectively avoid overloading on a single leg. Suitable for workpieces with four lifting points, it ensures stable hoisting and greater safety under heavy-load conditions.
Quick Selection Guide
Long structural members, two lifting points, efficiency priority → Two-Leg Sling + Matching Shackles!
Square & bulky components, four lifting points, stable heavy lifting → Four-Leg Sling + Matching Shackles!
Key Safety Considerations
1. Load capacities of complete slings and shackles must be matched. Mixing different sizes and ratings is strictly prohibited.
2. Control the sling angle. The included angle of four-leg slings shall not exceed 120° to prevent load amplification.
3. Inspect slings for wear and shackles for cracks or deformation before operation. Damaged units shall be scrapped immediately.
4. Ensure even load sharing among all four legs during lifting to prevent eccentric loading on one leg.
Two legs for higher efficiency; four legs for greater stability. Use slings as a complete set with corresponding shackles, conduct hoisting in compliance with specifications, and uphold the bottom line of safety.
