Longer Forks Versus Fork Extensions

Forklift forks must support at least two-thirds of the load's length. For example, if an operator handles 6 ft. square crates, the forks should be a minimum of 4 ft. long. Fork extensions can temporarily increase fork length, but for consistent heavy load handling, longer forks are a safer and more reliable option.

Forklift Extensions: Application and Load Center

Fork extensions are best suited for handling occasional large, lightweight loads. They should not be used to extend the reach of the forks for picking up loads from the back or sides with the fork tips. Additionally, fork extensions should never be homemade and must include a retainer, such as a heel hook or chains, to secure them properly to the forks.

Fork Extensions And Load Capacity

Fork extensions do not significantly reduce forklift capacity when used correctly, nor do they automatically extend the load center beyond the forklift’s ratings. The load center refers to the dimensional center of the load being handled, and an increased load center can create more leverage, increasing the risk of tipping. To make safer decisions regarding stability, operators can refer to the manufacturer’s data tag, which includes ratings for multiple load centers.

Longer Forks: Flexibility and Stability

If a forklift frequently handles larger loads near its rated capacity, using longer forks is the best option. Longer forks provide greater stability and eliminate the need for an updated capacity tag, which is required when using fork extensions. Fork extensions are considered attachments under ANSI Standard B56, and OSHA 1910.178 requires capacity changes to be indicated when using such attachments. 

Beyond regulations, longer forks offer a more stable and structurally sound solution, reducing the risk of tipping and enhancing safety.
