Component, the failure of which would result in a risk to the health and safety of
persons using the crane or located in its vicinity.
3.2
l) emergency retrieval system.
5.6.3 Written report and follow-up
A written report shall be furnished on completion of the inspection. An expert engineer
shall assess the results and shall
a) specify the defects, wear and where attention is necessary to ensure its
continued safe operation,
b) identify components that require particular attention in subsequent periodic
inspections, and
c) determine the reasonable practicability of applying the requirements of the latest
edition of the relevant Standard.
For those cranes and components listed in 5.6.1 b) and 5.6.2 e), the assessment
should be supervised by an expert engineer.
Following the major inspection, a deemed design life, where required, shall be
determined by the expert engineer (see Annex D) supervising the last major inspection.
Subsequently, the crane shall either be subjected to the programme of inspection as
part of the periodic inspection specified in 5.4, or reassessed by a competent person
within a five-year period. The critical components identified by the assessment shall
be inspected.
5.7 Enhanced periodic inspection
Enhanced periodic inspection may be carried out as an alternative to major inspection
(see 5.6). After the first five years of service, and within five years thereafter, periodic
inspections shall be structured to ensure all critical components are inspected, and
tested where appropriate. The manufacturer’s or user organization instructions may
also detail requirements for enhanced periodic inspections. The scheduling of
components for inspection shall be based on the crane’s operational history and
anticipated future usage, and the criticality and condition of the component or as
assessed by ISO 12482-1 procedures. The schedule shall be recorded and updated...
