This part of ISO 7296 establishes graphical symbols for use on operator controls and other displays on mobile cranes as defined in ISO 4306-2.

NOTE 1 Any ambiguity between the graphical symbols in this part of ISO 7296 and those in ISO 7296-1 will be resolved in the next revision of ISO 7296-1.

NOTE 2 The foreword lists other parts of ISO 7296 where graphical symbols for specific forms of machinery and equipment may be found.

This document specifies load actions to be used together with the standards EN 13001-1 and EN 13001-3, and as such they specify conditions and requirements on design to prevent mechanical hazards of cranes, and provides a method of verification of those requirements.

NOTE Specific requirements for particular types of crane are given in the appropriate European Standard for the particular crane type.

The following is a list of significant hazardous situations and hazardous events that could result in risks to persons during normal use and foreseeable misuse. Clause 4 of this document is necessary to reduce or eliminate the risks associated with the following hazards:

a) instability of the crane or its parts (tilting);

b) exceeding the limits of strength (yield, ultimate, fatigue);

c) elastic instability of the crane or its parts (buckling, bulging);

d) exceeding temperature limits of material or components;

e) exceeding the deformation limits.

This document is not applicable to cranes that are manufactured before the date of its publication as EN.

This document specifies design requirements for non-powered access installed on cranes.

NOTE 1 For other type of access a requirement for information to be supplied is specified.

This document covers access to control stations and all access required for maintenance, certain erection and dismantling operations (see below) and emergency.

For those cranes which are intended to be erected and dismantled at their places of work, specific requirements for the access needed during these operations are given in the appropriate European Standards for specific crane types.

NOTE 2 Specific requirements for access on particular types of cranes are given in the appropriate European Standard for the particular crane type.

The dimensions given in this document do not take into account the safety distances related to:

— guarding;

— relative movement between crane and adjacent structure;

— hazardous surface temperature;

— electrical equipment.

The significant hazards covered by this document are identified in Clause 4.

This document is not applicable to cranes which are manufactured before the date of publication by CEN of this standard.
