Why choose the TWN0851 GK8 shortener?

• Exact fit for 26 mm hardware: Ensures secure pin engagement and minimizes play under load.
• High-strength performance: Grade 80 steel provides robust resistance to wear and impact in harsh lifting environments.
• Clear, certified standards: EN1677-compliant, so you can trust compatibility with other certified shackles, hooks, and chains.
• Designed for 20 mm G80 chains: Specifically engineered to pair with common G80 chain assemblies, reducing the risk of mismatch and mishandling.
• German manufacturing heritage: Known for precision manufacturing, tight tolerances, and consistent quality across components.

Ideal use cases

• Shortening a lift chain to create a compact, clean rigging run on a temporary or mobile crane setup.
• Setting up adjustable rigging points where chain length needs to be tuned for balance and load path optimization.
• Repairs or retrofits of existing hoisting configurations where a reliable GK8 clevis shortener is required to maintain WLL.
• Maintenance-friendly installations where quick on-site checks ensure the load path remains uncompromised.

Maintenance and safety tips to get the most from your shortener:

• Inspect for wear, deformation, or corrosion before each lift. Do not use if any sign of damage is present.
• Always verify the WLL aligns with the chain size and the overall lifting assembly—do not exceed 21.2 tonnes.
• Ensure proper engagement of the clevis with the mating 26 mm hardware and 20 mm G80 chain links.
• Store in a clean, dry environment when not in use to preserve the integrity of the Grade 80 steel.

With the Thiele TWN0851 GK8 Clevis Shortener, you get a purpose-built, German-engineered component that delivers predictable performance, safety, and compatibility within your lifting system. If you’re upgrading or standardizing your rigging gear, this shortener’s combination of precise sizing, EN1677 conformity, and a 21.2 t WLL makes it a dependable choice for heavy-duty applications.
