2.5.13 Fork Ratings
All approved forks for this vehicle are marked with a
maximum load capacity rating. This rating (1) is stamped
on the right edge of the fork just below the fork pivot
shaft (2). The rating is listed in U.S. pounds and based
upon a 24" (610 mm) load center (3) (11K carriage) or
48" (1219 mm) load center (3) (7K carriage). This rating
specifies the maximum load capacity that the individual
fork can safely carry at the maximum specified load
center.
Since forks are always used in multiples, the total rating
of any combination of forks will be the sum of their rated
capacity. All forks should be used in matched pairs.
