Maintenance, Inspection and Thorough Examination of Mobile Cranes

17.0 Developing the Defined Scope of Thorough Examination
17.1 Introduction
It is important that a defined scope of thorough examination is drawn up before a
thorough examination is undertaken on a mobile crane. This should cover at least the
following:-
� What is to be looked at;
� How often;
� Examination methods to be employed;
� Details of any supplementary reports and tests;
� Anticipated duration.
The defined scope of thorough examination for an individual crane will comprise
of generic elements applicable to most cranes, supplemented by crane specific
elements derived from consideration of information including:-
� Crane specific details
� Maintenance and repair data
� Manufacturer’s information (alerts and technical bulletins)
� In-service history
� Proposed future use
This process is shown in Figure 4. below.
