Cranes - Inspections - Part 1: General

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

when altered.

NOTE: The periods indicated in this clause are based upon a 10 year design life.

The sequence of inspections may be altered based on the crane's usage, providing all

critical components are inspected in the five year period.

The inspections shall include all items specified in the instructions for periodic

inspection (see 5.4) together with all frequent inspection items (see 5.3), which should

include
