Engineered in Germany, the Thiele TWN0851 GK8 Clevis Shortener is a precision rigging accessory designed to shorten 20 mm G80 chain slings with confidence and control. Crafted to meet EN1677 standards and built from high-strength Grade 80 steel, this component helps you keep loads centered, reduce chain slack, and maintain safe lift angles during hoisting and rigging operations.

• Compatibility: Designed for 20 mm G80 lift chain assemblies, delivering a seamless fit with standard 20 mm chain slings.
• Working Load: Rated for 12.5 tons (12,500 kg), providing a robust shortening solution for heavy lifts without compromising chain integrity.
• Material & Standards: Grade 80 steel—quenched and tempered for high strength and durability—paired with EN1677-compliant construction for reliable performance in overhead lifting.
• Origin & Quality: Made in Germany by Thiele, ensuring tight tolerances, precise machining, and long service life.
• Identification & Logistics: Product No. F34970 with GK8 clevis configuration; shipped directly from our supplier for timely, direct-to-job-site delivery.

Why this matters for your lifting setup: using a purpose-built shortener like the TWN0851 GK8 preserves load alignment, minimizes lateral stress on the chain, and simplifies achieving the exact lift point you need. It’s especially valuable when you must adjust chain length on the fly, keep multiple slings synchronized, or keep a tight, safe angle on the load.

Ideal use scenarios include construction and civil works where precise chain-length control is essential, shipyards and offshore operations requiring reliable overhead lifting with heavy loads, and maintenance or rigging teams that routinely reconfigure slings for different lifts. If you depend on 20 mm G80 chain assemblies and demand top-tier German engineering, this shortener is purpose-built to deliver consistent, repeatable performance.

Practical tips for best results

• Verify the load is within the 12.5T rating prior to lifting and ensure the load geometry stays within the clevis’s safe operating range.
• Inspect the shortener for signs of wear, corrosion, or deformation before each use; replace if any damage is detected.
• Attach the shortener so that the load remains centered on the chain, avoiding side loading or cross-loading conditions.
• Store in a clean, dry area and lubricate pivot points only as recommended by manufacturer guidelines.
