INSPECTION
PROCEDURES
To maintain continuous and satisfactory operation, a regular
inspection procedure must be initiated to replace worn or damaged
parts before they become unsafe. Inspection intervals must be
determined by the individual application and are based on the
type of service to which the hoist will be subjected and the degree
of exposure to wear, deterioration or malfunction of the critical
components.
The type of service which the hoist is subjected can be classified as
"NORMAL," "HEAVY," "SEVERE."
NORMAL SERVICE
Involves operation with randomly distributed loads within the rated
load limit, or uniform loads less than 65 percent of rated load for not
more than 25 percent of the time.
HEAVY SERVICE
Involves operating the hoist within the rated load limit which exceeds
normal service.
SEVERE SERVICE
Is normal or heavy service with abnormal operating conditions.
Two classes of inspection, FREQUENT and PERIODIC, must be
performed.

FREQUENT INSPECTIONS

These inspections are visual examinations by the operator or other
designated personnel. Records of such inspections are not required.
The frequent inspections are to be performed monthly for normal
service, weekly to monthly for heavy service, and daily to weekly for
severe service, and they should include those items listed in Table 4.

PERIODIC INSPECTIONS

These inspections are visual inspections of external conditions by
an appointed person. Records of periodic inspections are to be
kept for continuing evaluation of the condition of the hoist. Periodic
inspections are to be performed yearly for normal service, semi-
annually for heavy service and quarterly for severe service, and they
are to include those items listed in Table 5.
Any deficiencies are to be corrected before the hoist is returned
to service. Also, the external conditions may show the need for
disassembly to permit a more detailed inspection, which, in turn,
may require the use of non-destructive type testing.

PREVENTIVE MAINTENANCE

In addition to the above inspection procedure, a preventive
maintenance program should be established to prolong the useful
life of the hoist and maintain its reliability and continued safe use.
The program should include periodic and frequent inspections
with particular attention being paid to the lubrication of the various
components using the recommended lubricants (see page 15).

HOOK INSPECTION

Hooks damaged from chemicals, deformations or cracks, or
that have more than a 10° twist from the hook's unbent plane or
excessive opening or seat wear must be replaced. Also, hooks
that are opened and allow the latch to not engage the tip, must be
replaced. Any hook that is twisted or has excessive throat opening
indicates abuse or overloading of the unit. Inspect other load
sustaining parts for damage.
On latch type hooks, check to make sure that the latch is not
damaged or bent and that it operates properly with sufficient spring
pressure to keep the latch tightly against the tip of the hook and
allow the latch to spring back to the tip when released. If the latch
does not operate properly, it should be replaced. See Figure 14 to
determine when the hook must be replaced.
