Introduction
This document has been prepared to be a harmonized standard to provide one means for the mechanical
design and theoretical verification of cranes to conform with the essential health and safety requirements
of the Machinery Directive 2006/42/EC modified.
This document is a type C standard as stated in !EN ISO 12100:2010".
The machinery concerned and the extent to which hazards, hazardous situations and events are covered
are indicated in the scope of this standard.
!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);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises);
— consumers (in case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate in the drafting
process of this document."
When provisions of this type C standard are different from those which are stated in type A or B
standards, the provisions of this type C standard take precedence over the provisions of the other
standards, for machines that have been designed and built according to the provisions of this type C
standard.
1 Scope
!This document specifies the safety characteristics and the requirements:
— of anti-collision devices and systems intended for installation on self-erecting tower cranes and
tower cranes erected from parts for construction work (as defined in EN 14439:2006+A2:2009) to
avoid:
— the risks of collision between several cranes;
— the risks of collision between a crane in service and fixed obstacles;
— travelling over prohibited zones;
— of working range limiting devices.
NOTE Anti-collision devices and systems and working range limiting devices according to this document are
safety components.
This document deals with all significant hazards, hazardous situations and events relevant to anticollision
devices and systems installed on tower cranes, when used as intended and under conditions foreseen by
the manufacturer. This document specifies the appropriate technical measures to eliminate or reduce
risks arising from the significant hazards (see Clause 4).
This document is not applicable to anti-collision devices and systems which are manufactured before the
date of publication by CEN of this document."

5 Technical requirements
5.1 General
5.1.1 Components of anti‐collision devices and systems
The anti-collision device consists of a set of input devices, e.g. sensors, output devices and a logic module.
All output devices are already installed on the crane while some of the necessary input devices could need
to be retrofitted.
An anti-collision device and system shall include at least the following parts:
— processing unit;
!— power supply unit;"
— display for fixed control stations (for use by the crane operator);
— slewing sensors and, if necessary, hoisting, travelling, trolleying and luffing sensors;
— means of overriding;
— means of communication (radio, cable);
— outside indicators, see 6.9;
— interface with the tower crane.
Some of these parts may already be part of the crane, for example, the sensors.
5.1.2 Shape of the components of anti‐collision devices
For all the components of the anti-collision device installed near the control station,
EN 13557:2003+A2:2008, 5.2.1.9 shall apply.
5.1.3 Requirement for the mechanical installation of the components of anti‐collision devices on
the crane
When the anti-collision device requires having component(s) mechanically installed on the crane, they
shall be designed to be assembled and fixed in such a way to prevent errors of fitting, to prevent them
from inadvertent movement and from falling during normal operation.
The mechanical installation shall not affect the tower crane functions.
5.1.4 Crushing or shearing hazards between moving parts
When a component of the anti-collision device presents moving parts when installed on a crane, means
of guarding shall be provided in order to avoid any crushing or shearing hazards of the persons accessing
the crane with the moving parts.
5.1.5 Controls
When a component of the anti-collision device presents a means of control, it shall conform to
