Van Beest Green Pin® UMTS Grade 100 Welded Master Link Assembly

The Van Beest Green Pin UMTS Grade 100 Welded Master Link Assembly is a pre-assembled set containing a Grade 100 oblong master link with matched coupling links, ready for immediate integration into multi-leg chain sling builds. Grade 100 alloy steel provides 25% higher working load limits compared to Grade 80 assemblies of the same size.

Key Features

• Grade 100 alloy steel master link and coupling links
• Pre-assembled — coupling links matched to master link capacity
• 25% higher WLL than equivalent Grade 80 assemblies
• Flash-butt welded construction on all components
• Individually proof tested at 2.5× WLL
• Compliant with EN 1677-4 standards

Common Applications

• Double and multi-leg Grade 100 chain sling assemblies
• High-capacity crane and hoist rigging
• Heavy lift operations in construction, mining, and offshore
• Applications where compact size and reduced weight improve safety and handling

Why Van Beest?

The UMTS assembly takes the guesswork out of component selection — every piece is matched, tested, and certified together by Van Beest. Upgrading to Grade 100 means higher capacities in a lighter, more compact package, with the same rigorous quality and traceability Green Pin is known for.

Governing Standards

• ASME B30.9 — slings (web, round, wire rope, chain) inspection and use
• ASME B30.26 — rigging hardware (shackles, eye bolts, links, turnbuckles)
• ASME B30.10 — hooks
• OSHA 1910.184 and 1926.251 — general industry and construction sling safety
• WSTDA WS-2 and RS-1 — web and round sling design
• 49 CFR 393.102 to 393.130 — DOT cargo tie-down
• NACM — welded steel chain grade specs

Inspection & Safety

Before every use: visual check for cracks, corrosion, distortion, wear, and illegible markings. Annually (minimum): documented periodic inspection by a trained inspector. Remove from service at first sign of damage. Never repair rigging hardware by welding, heating, or bending.

WARNING: Improper use of rigging can cause death or serious injury. Never exceed the rated Working Load Limit. Apply derating for side-loading, elevated temperature, or chemical exposure. Final application decisions must be made by a Qualified Person per OSHA 1926.32(m).
