European foreword
This document (prEN 12077-2:2023) has been prepared by Technical Committee CEN/TC 147 “Cranes -
Safety”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 12077-2:1998+A1:2008.
In comparison with the previous edition, the following technical modifications have been made:
— updated reference documents and cross-references;
— revised grammar and linguistic consistency;
— revised the List of significant hazards and moved it to Annex A;
— revised Annex ZA and added a Bibliography;
— revised and updated part 3;
— revised and updated subclauses 4.2.6, 4.2.7, 4,2.9, 4.3.1, 4.3.2, 4.3.4, 4.3.5, 4.4.1.1, 4.4.1.2, 4.5.1.1,

— removed subclauses 4.5.3, 4.6.2.3, 4.7.2;
— revised and updated Table 1.
This document has been prepared under a Standardization Request given to CEN by the European
Commission and the European Free Trade Association, and supports essential requirements of
EU Directive(s) / Regulation(s).

Introduction
This document is a harmonized standard to provide one means for limiting and indicating devices for
cranes to conform with the essential health and safety requirements of the Machinery Directive, as
mentioned in Annex ZA.
This European Standard is a type-C standard as stated in EN ISO 12100.
This document is of relevance, in particular, for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— service providers, e.g. for maintenance (small, medium and large enterprises).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.
The machinery concerned and the extent to which hazards are covered are indicated in the scope of this
standard.
When requirements of this type-C standard are different from those which are stated in type-A or type-B
standards, the requirements of this type-C standard take precedence over the requirements of the other
standards for machines that have been designed and built according to the requirements of this type-C
standard.

1 Scope
This document specifies general requirements for limiting and indicating devices used in cranes. These
devices restrict operation or provide operational information for the operator or other persons. Specific
requirements for particular types of cranes are given in the appropriate European Standard for the
particular crane type.
This document does not cover erection, dismantling, or changing the configuration of a crane.
The hazards covered by this document are identified in Annex A.
This document is applicable to cranes which are manufactured after the date of approval by CEN of this
document.

3.7
indicator
device to provide warnings and/or data to facilitate control of the crane within its design parameters
