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.
Table 5-2 Inspection Intervals
Service FREQUENT Inspection PERIODIC Inspection
Normal Service Monthly Yearly
Heavy Service Weekly to Monthly Semiannually
Severe Service Daily to Weekly Quarterly
Special or Infrequent Service As recommended by a qualified
person before and after each
occurrence. As recommended by a qualified person before
the first such occurrence and as directed by the
qualified person for any subsequent occurrences.
5.3 Every Lift Inspection
5.3.1 Inspections should be made before and/or during every lift in accordance with Table 5-3, “Every Lift Inspection.” The operator shall
inspect for any indication of damage, including observations during operation for any damage that might occur during the lift.
Table 5-3 Every Lift Inspection
Surface of the load for debris.
Condition and operation of the controls and moving/functional components.
5.4 Frequent Inspection
5.4.1 Inspections should be made on a FREQUENT basis in accordance with Table 5-4, “Frequent Inspection.” Included in these
FREQUENT Inspections are observations made during operation for any defects or damage that might appear between Periodic
Inspections. Evaluation and resolution of the results of FREQUENT Inspections shall be made by a designated person such that
the clamp is maintained in safe working condition.
Table 5-4 Frequent Inspection
All functional operating mechanisms for proper operation and adjustment, maladjustment.
Lifting system components for deformation, cracks, or significant wear.
Structural members for deformation, cracks, or excessive wear.
Loose or missing fasteners, nameplates, and warning labels.
Connection points between Clamp and Hoist or/and support structure in accordance with ANSI/ASME B30.20 and
