Fork Extension Sleeve — Mitsubishi & Caterpillar Forklift Compatible Steel Fork Extensions

This steel fork extension sleeve is designed specifically for Mitsubishi and Caterpillar counterbalance forklifts, providing extended fork reach for handling oversized pallets, long material bundles, and wide-profile loads that exceed standard fork length. Manufactured to match the fork profile specifications common to Mitsubishi FD/FG series and Caterpillar DP/GP series forklifts in the 2-8 ton capacity range, the sleeve slides directly over the existing forks without requiring modifications to the carriage or fork mounting. The slip-on design with heel-to-carriage contact eliminates the forward creep common in poorly fitted universal sleeves, while the steel construction provides the bending stiffness necessary to maintain fork straightness under rated load at the extended load center. Custom design services are available with 3-day turnaround and 7-day custom sample production — ideal for operations requiring non-standard fork sleeve dimensions, special surface treatments, or branded OEM specifications. 1-year warranty with free replacement parts and online technical support included.

Installing fork extension sleeves on Mitsubishi and Caterpillar forklifts requires confirming fork cross-section compatibility — measure your fork width and thickness before ordering, as Mitsubishi and Caterpillar use different fork profiles across model years and capacity classes. Slide the sleeve over each fork until the heel seats against the carriage face; a properly fitted sleeve requires minimal force to install but no visible gap at the heel contact point. Post-installation, verify the sleeve does not contact the load backrest, mast channels, or tilt cylinder at any position in the full lift and tilt range. Derate the forklift capacity according to the new load center created by the extended forks — as a general rule, a 50% fork length extension reduces safe working load by approximately 30-40%, but always consult your specific forklift load chart. Inspect sleeve welds and heel contact surfaces monthly for crack initiation, especially at the heel-to-channel transition zone where bending stress concentrates. Free replacement parts are available under warranty for manufacturing defects.

These extension sleeves fit Mitsubishi FD/FG and Caterpillar DP/GP series forklifts. Custom sizing available with 3-day design and 7-day sample turnaround.
