considered necessary, subjected to a nondestructive crack detection process, special
attention being paid to the heel and welds attaching the mounting components to the fork
blank. This inspection for cracks must also include any special mounting mechanisms of
the fork blank to the fork carrier including bolt-type mountings and forged upper mounting
arrangements for hook or shaft-type carriages. The forks shall not be returned to service
if surface cracks are detected.
2. Straightness of Blade and Shank. The straightness of the upper face of the blade and
the front face of the shank shall be checked. If the deviation from straightness exceeds
0.5% of the length of the blade and/or the height of the shank, respectively, the fork shall
not be returned to service until it has been repaired in accordance with para. Repair and
Testing.
3. Fork Angle (Upper Face of Blade to Load Face of the Shank). Any fork that has a
deviation of greater than 3 deg from the original specification shall not be returned to
service. The rejected fork shall be reset and tested in accordance with para. Repair and
Testing.
4. Difference in Height of Fork Tips. The difference in height of one set of forks when
mounted on the fork carrier shall be checked. If the difference in tip heights exceeds 3%
of the length of the blade, the set of forks shall not be returned to service until repaired in
accordance with para. Repair and Testing.
5. Positioning Lock (When Originally Provided). It shall be confirmed that the positioning
lock is in good repair and correct working order. If any fault is found, the fork shall be
withdrawn from service until satisfactory repairs have been effected.
6. Wear
(1) Fork Blade and Shank. The fork blade and shank shall be thoroughly checked
for wear, special attention being paid to the vicinity of the heel. If the thickness is
reduced to 90% of the original thickness, the fork shall not be returned to service.
(2) Fork Hooks (When Originally Provided). The support face of the top hook and the
retaining faces of both hooks shall be checked for wear, crushing, and other local
deformations. If these are apparent to such an extent that the clearance between the
fork and the fork carrier becomes excessive, the fork shall not be returned to service
until repaired in accordance with para. Repair and Testing.
7. Legibility of Marking (When Originally Provided). If the fork marking is not clearly legible,
it shall be renewed. Marking shall be renewed per instructions from original supplier.
Repair and Testing.
1. Repair. Only the manufacturer of the fork or an expert of equal competence shall decide
if a fork may be repaired for continued use, and the repairs shall only be carried out by
such parties.
It is not recommended that surface cracks or wear be repaired by welding. When repairs
necessitating resetting are required, the fork shall subsequently be subjected to an appropriate
heat treatment, as necessary.
2. Test Loading. A fork that has undergone repairs other than repair or replacement of
the positioning lock and/or the marking, shall only be returned to service after being
submitted to, and passing except that the test load shall correspond to 2.5 times the
