scope:

This Technical Report provides a guide to International Standards applicable to mobile cranes (crawler cranes, railway cranes, wheel-mounted cranes and any variations thereof that retain the same fundamental characteristics) and a summary of related provisions. Special adaptations of the general types of machine covered, where applicable, also fall within its scope.

NOTE According to the ISO Directives, Part 2, the verbal forms used to identify provisions in an International Standard are

- "shall" or "shall not", used to indicate requirements strictly to be followed in order to conform to the document and from which no deviation is permitted,

- "should" or "should not" for recommendations, indicating that among several possibilities one is recommended as particularly suitable, without mentioning or excluding others, or that a certain course of action is preferred but not necessarily required, or that (in the negative form) a certain possibility or course of action is deprecated but not prohibited, and

- "may" or "need not", used to indicate a course of action permissible within the limits of the document.

Purpose

The purpose of this Technical Report is to

a) identify the many International Standards relevant to mobile cranes and their safety (see Bibliography for a complete listing),

b) summarize the content of those documents,

c) promote mobile crane safety by the delineation of these standards, so that the incorporation of their provisions into the design and use of mobile cranes will guard against, and minimize, injury to workers and damage to equipment,

d) facilitate the work of all those working in the field of mobile cranes (designers, supervisors and others either directly or indirectly responsible for the safe use and maintenance of the machines) with a need to consult the current standards relating to mobile cranes, and

e) contribute to further international harmonization of mobile crane standards.
