5.0 Inspection
5.1 Initial Inspection – Prior to initial use, all new, altered, or modified clamps shall be inspected by a designated person to ensure
compliance with the applicable provisions of this manual.
5.2 Inspection Classification – The inspection procedure herein is based on ANSI/ASME B30.20. Inspections for clamps in regular service
are divided into EVERY LIFT, FREQUENT and PERIODIC groups based upon the intervals at which inspection should be performed. The
intervals in turn are dependent upon the degree of service and usage the clamps are subjected to. EVERY LIFT inspection should be
made before/or during every lift. FREQUENT and PERIODIC inspections should be made with respective intervals between inspections as
defined in Table 5-2.
