Pallet Truck Fork Extension Sleeves — Heavy-Duty Steel Fork Attachment for Pallet Trucks & Forklifts

These heavy-duty steel fork extension sleeves are engineered for pallet trucks and larger forklift applications where extended fork reach is required for handling oversized loads, wide-profile pallets, and long material bundles. With a gross weight of 254kg per pair and a package dimension of 167×15×5 cm, these are industrial-grade extensions built for continuous heavy-load service — not lightweight consumer sleeves. The substantial wall thickness provides the bending stiffness required to maintain fork straightness under full-rated load at the extended load center, preventing the dangerous downward deflection that lighter sleeves experience when overloaded. These sleeves are designed as a slip-on fork attachment with the heel end contacting the fork carriage face, secured in position to prevent forward movement during load handling. For operations handling steel coils, concrete barriers, construction materials, or long pipe bundles, these extensions provide the additional fork length necessary to safely cradle the load without dangerous overhang conditions.

Installing heavy pallet truck fork extension sleeves requires mechanical assistance due to the 254kg weight — a second forklift or overhead crane is recommended for safe positioning. Slide each sleeve over the parent fork ensuring the heel seats squarely against the carriage face. Verify the fork width and thickness match the sleeve interior channel before applying load — a loose-fitting sleeve creates a stress concentration at the heel contact point that can cause sleeve or parent fork deformation under load. Due to the substantial mass of these extensions, always verify the forklift’s rated capacity is derated for the combined weight of the extension sleeve plus the load at the new load center. A 167cm extension on a standard 122cm fork creates a significantly extended load center — consult your forklift load chart and never exceed the derated capacity. Post-installation, test-lift a known-weight load at low height to confirm stability before entering production operation. Common failure modes on heavy sleeves include heel weld cracking from repeated impact with the carriage face, longitudinal stress cracking along the channel bend radius, and bolt-hole elongation on retained-type sleeves.

These pallet truck fork extension sleeves are designed for standard ITA Class II and III fork profiles. Confirm your fork dimensions before ordering.
