Chain slings are critical for industrial lifting, but component quality determines safety. This guide covers G80/G100-rated master links, connecting links, and self-locking hooks, aligned with ASME and OSHA standards.
Various models of accessories are available for customized products, please contact us for details.
· Function: Connects sling legs to lifting devices (e.g., cranes).
· Material:
· G80: Heat-treated alloy steel for general industrial use (WLL up to 10T).
· G100: High-strength alloy for heavy-duty lifts (WLL up to 20T).
· Certification: ASME B30.26 proof-tested at 2× WLL.
· Grades:
· G80: Standard alloy chains for general use.
· G100: Premium alloy for extreme loads.
· Safety Factor: 4:1 (WLL = 25% break strength).
· Function: Secures loads with automatic latch locking.
· Safety Features:
· Forged Steel: Tested to 3× WLL.
· Self-Locking: Prevents accidental release during lifts.
· Applications: Steel beam rigging, machinery transport.
· Powder coated, different color is available as per request.
· Working load limit permanently shown on the body.
· Max proof load is 2.5 times of the working load limited
· Min. Breaking strength is 4 times of the W.L.L.
· Powder coafed, different color is available is per request.
· Working load limit permanently shown on the body.
· Max proof load is 2.5 times of the working load limited.
· Min. Breaking strength is 5 times of the W.L.L.
Type | Components | Max Load (WLL) | Applications |
Single-Leg | 1 G100 chain + 2 self-locking hooks | 20 tons | Heavy machinery lifts |
Double-Leg | 2 G80 chains + master link | 8 tons (at 60°) | Construction beams, pipes |
Triple-Leg | 3 G80 chains + connecting links | 6 tons (per leg) | Irregular loads (e.g., engines) |
00001. Pre-Use Inspection:
· Check master links for cracks or deformation.
· Verify self-locking hooks latch securely.
00002. Load Limits:
· Never exceed WLL (use ASME formula: WLL = Chain Strength / 4).
00003. Storage:
· Hang vertically in dry, non-corrosive environments.
G80/G100 chain sling components ensure safe, heavy-duty lifting when paired with proper configurations and inspections. Always prioritize certified parts and ASME/OSHA compliance. +86 18766656705
