5.5 Occasionally Used Hoist
Hoists that are infrequently used shall be inspected as follows before placing the hoist in service:
Hoist idle more than one year: Inspect per Periodic Inspection.
Hoist idle more than one month, less than one year: Inspect per Frequent Inspection.
5.6 Inspection Reports
Dated inspection reports and records should be maintained for the hoist Periodic Inspection intervals. These
records should be stored where they are available to personnel involved with the inspection, maintenance or
operation of the hoist.
A long range chain inspection program should be established and should include records of an examination of
the chains that are removed from service to create a relationship between visual observation and actual condition
of the chain.
5.7 Inspection Methods and Criteria
This section covers the inspection of specific items. The list of items in this section is based on those listed in
ANSI/ASME B30.16 for the Frequent and Periodic Inspection. In accordance with ANSI/ASME B30 volumes listed under
the General heading on the previous pages, these inspections are not intended to involve disassembly of the hoist.
Rather, disassembly for further inspection would be required if frequent or periodic inspection results so indicate. Such
disassembly and further inspection should only be performed by a certified or qualified person trained in the disassembly
and re-assembly of the hoist.
