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 document is a type-C standard as stated in EN ISO 12100:2010.
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 not applicable to cranes manufactured before the date of its publication.

4 Safety requirements and/or measures
4.1 General
Machinery shall comply with the safety requirements and measures of Clause 4. In addition, the machine
shall be designed according to the principles of EN ISO 12100:2010 for hazards relevant but not
significant which are not dealt with by this standard.
4.2 Limiters and indicators
4.2.1 The crane manufacturer shall select a device compatible with the intended use of the crane, taking
the following into account:
a) operating environment, e.g. temperature, relative humidity, condensation, vibration;
b) rated capacity;
c) crane characteristics;
d) electromagnetic compatibility.
4.2.2 The installation of limiters and indicators shall be carried out in a manner that does not reduce
the strength of the crane.
4.2.3 The effects (e.g. forces, stopping distances) resulting from the operation of the limiter shall be
within the design constraints of the crane.
4.2.4 Systems shall enable periodic functional checks to be carried out to verify that indicators are
operating correctly.
4.2.5 If interruption of the power supply occurs, the settings of limiters and indicators shall be retained.

transmitted to them during operation, erection, dismantling and maintenance of the crane.
4.2.7 Limiters and indicators shall have legible and durable markings on or adjacent to them, preferably
with symbols to indicate their function and mode of operation, and all indicators shall be compatible with
ergonomic principles in accordance with EN 614-2:2000+A1:2008.

European Standards for particular crane types.
4.3 General requirement for rated capacity limiters and indicators
4.3.1 Rated capacity limiters and indicators shall be provided on all cranes having a rated capacity of
1 000 kg or above, or an overturning moment of 40 000 Nm or above due to the rated capacity (see 3.10).
4.3.2 The rated capacity limiter and indicator shall perform in accordance with this standard for all
rated capacities and all the configurations described in the information for use of the crane.
4.3.3 If a crane can be operated with different configurations there shall be an indication of the crane
configuration for which the rated capacity limiter and indicator has been set. Where a configuration
selecting device is provided, a direct description of the configuration selected shall be
