5.6 Inspection Records
5.6.1 Dated inspection reports and records should be maintained at time intervals corresponding to those
that apply for the hoist’s PERIODIC interval per Section 5.2.4. These records should be stored where
they are available to personnel involved with the inspection, maintenance, or operation of the
hoist/trolley.
5.6.2 A long range rope inspection program should be established and should include records of examination
of ropes removed from service so a relationship can be established between visual observation and
actual condition of the rope.
5.7 Inspection Methods and Criteria
5.7.1 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
B30.16, 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. Only a
qualified person trained in the disassembly and re-assembly of the hoist or trolley should perform such
disassembly and further inspection.
