Fork Inspection; Fork Repair - UniCarriers 1F1 Operator's Manual

FORK INSPECTION

Ensure the forks are secured in their proper position and they are not
damaged.
!
WARNING
• Forks in use shall be inspected at intervals of not more
than 12 months (for single shift operations) or whenever
any damage or permanent deformation is detected. Severe
applications will require more frequent inspection. (see ANSI/
ITSDF B56.1 Section 6.2.8 for inspection and repair of forks
in service on lift trucks.)
• Individual Load Rating of Forks. When forks are used in pairs
(the normal arrangement), the rated capacity of each fork
shall be at lease half of the manufacturer's rated capacity of
the truck, and at the rated load center distance shown of the
truck's data plate.
• Fork inspection shall be carried out carefully by trained
personnel with the aim of detecting any damage, failure,
deformation, etc., which might impair safe use. Any fork that
shows such damage shall be withdrawn from service, and
shall not be return to service unless it has been satisfactorily
repaired in accordance with the current ANSI/ITSDF B56.1-
2012 standards.

FORK REPAIR

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.
