Heavy Duty Galvanized Forklift Fork Extension Sleeves — 1600-3000mm Multi-Length Slip-On Fork Covers

These heavy-duty galvanized forklift fork extension sleeves are slip-on steel covers designed to extend the effective length and load-support surface of standard forklift forks for handling oversized pallets, long pipes, lumber bundles, and wide-profile loads. Available in lengths from 1600mm to 3000mm and rated for safe working loads of 3-ton, 4.5-ton, 6-ton, and 8.5-ton capacities at a 600mm load center, these extensions accommodate a wide range of material handling applications — from warehouse pallet handling to heavy construction material transport. Constructed from structural-grade steel with a galvanized silver finish (painted option available), these sleeves resist rust in outdoor yards and high-moisture environments. The slip-on design features pre-drilled safety pin holes at the heel end to lock the sleeve onto the fork, preventing forward creep during load release. Each sleeve is engineered to the ITA standard fork profile for Class II and III carriages. Note: extending forks increases the load center and reduces effective lifting capacity — always verify the de-rated capacity with your forklift load chart before operation.

Installation requires no tools: simply slide each sleeve over the existing fork until the heel contacts the fork carriage face, then insert the safety pin through the pre-drilled hole to lock it in position. Before each use, verify both safety pins are fully seated and the sleeves show no forward movement when tugged. The most common installation error is using sleeves on forks of incorrect width or thickness — measure your fork cross-section and confirm it matches the sleeve channel dimensions before ordering. For multi-shift operations, remove the sleeves at the end of each shift and inspect the channels for debris accumulation that can score the parent fork surface. Store sleeves flat to prevent channel warping. The primary warning signs of sleeve degradation are visible cracks at the weld seams, elongated safety pin holes allowing excessive movement, and rust-through on painted versions where the coating has been scraped off by pallet contact.

These fork extension sleeves are available in custom lengths from 1600mm to 3000mm with standard ITA Class II/III fork profiles.
