Gunnebo UKN 15 Ton Weld-on Bucket Hook

Gunnebo UKN Universal Weld-On Hook – The Original Excavator Hook. Still the Best.

Since 1975, one hook has defined the standard for excavator lifting points. The Gunnebo UKN Universal Weld-On Hook was the first of its kind — and nearly five decades later, it remains the industry-standard choice for leading OEMs and contractors worldwide. When you need to transform an excavator, backhoe, or construction attachment into a safe, certified lifting tool, the UKN is the hook the industry trusts.

Weld It Once. Lift with Confidence.

The UKN's slightly curved base plate is engineered for welding directly to buckets, booms, lifting frames, and other construction machine attachments — creating a permanent, certified lifting point without the need for secondary hardware or complex mounting systems. Once welded, the UKN provides a reliable, traceable lifting anchor rated to a 5:1 design factor and 100% individually proof tested at 3× WLL — a testing standard that goes well beyond what many competing products require.

Built for the Toughest Job Sites

Forged from alloy steel, hardened and tempered throughout, the UKN delivers the impact resistance and fatigue performance that construction, forestry, and utility environments demand. The heavy-duty latch features an ergonomic handle, a hardened and tempered latch body, and a stainless steel spring for long-term corrosion resistance and reliable engagement — even in mud, dust, and extreme weather conditions.

Every UKN is clearly marked with country of origin, traceability code, model, and size, and meets the requirements of EN 474-1 — the European standard governing excavator lifting points — making it the correct specification for both OEM factory fitting and aftermarket installation on certified lifting operations.

Key Applications:

• Excavators and backhoes — factory-fitted or aftermarket
• Construction machine lifting frames and attachments
• Forestry and utility material handling operations
• Any application requiring a permanent, certified weld-on lifting point
