3-Ton Forklift Fork — 40Cr Alloy Steel, 48″/60″/72″ Length Options, ISO9001 Certified

This 3-ton rated forklift fork is manufactured from 40Cr alloy steel — a chromium-molybdenum grade widely specified for high-stress structural components in material handling equipment. With a 45×122mm cross-section and available in 48-inch, 60-inch, and 72-inch lengths, this fork covers the most common fork specifications for 3-ton counterbalance forklifts across building material, manufacturing, and general industrial applications. The 40Cr material provides superior yield strength and fatigue resistance compared to standard carbon steel forks, particularly important for operations involving frequent load cycling, shock loading from uneven surfaces, and continuous multi-shift service. ISO9001-2008 certified with 100% professional testing, each fork undergoes dimensional verification and surface inspection before shipment. The black finish provides basic corrosion protection for indoor and covered outdoor operations. 1-year warranty, 24-hour online service support, and a 60kg packaged weight with 122×40×60cm package dimensions.

Installing 40Cr alloy steel forks follows standard fork replacement procedures, but the harder material requires attention to carriage bar compatibility. 40Cr forks are harder than standard carbon steel carriage bars, which can accelerate carriage bar wear at the fork heel contact zones if the carriage bar surface is already worn or pitted. Before installing 40Cr forks, inspect the carriage bar for wear grooves and surface roughness — if the carriage bar shows significant wear, replace it or install wear plates between the fork heel and carriage bar to distribute contact pressure. The 45×122mm cross-section is standard for ITA Class II/III 3-ton carriages, but verify your carriage bar slot width before ordering. After installation, verify fork locking pins engage fully and forks slide freely across the carriage bar — 40Cr’s hardness can make fork repositioning slightly stiffer than carbon steel forks until the heel surfaces bed in during the first few operating hours. For operations selecting between 48″, 60″, and 72″ lengths, longer forks increase load stability for deep pallets and wide loads but reduce net lifting capacity due to the extended load center and increased fork weight. 1-year warranty covers manufacturing defects; 24-hour online service available for technical support.
