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;
— 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
EN 13557:2003+A2:2008.
5.1.6 Cableless means of communication
When the anti-collision device is using a cableless means of communication for a safety function then this
safety function shall fulfil the requirements specified in 5.1.7.
5.1.7 Safety functions
An anti-collision device and the therein used safety related parts of the control system shall perform at
least the following safety function:
Limitation of a static or dynamic changing working range.
This safety function is intended to reduce the risk of a collision of all possible parts of interfering cranes
(e.g. hoist rope against jib or counter-jib of an adjacent crane) or the risk of entering into a prohibited
zone. Adapted to the characteristics of the cranes drives, the anti-collision device has to give control
commands to slow down and stop the motion prior to reaching the actual stop limit.
This safety function and the therein used safety related parts of the control system shall fulfil at least the
Performance Level PL c, category 2 according to EN ISO 13849-1:2015.
NOTE An emergency stop initiated at the crane affects only the crane at which it has been released. This
information can be transferred to the ACD but does not initiate a reaction at other cranes, which are part of the ACS.
In case of transmission of data related to safety functions between the ACDs over a server and/or
processing of the data on this server, this server should be a safety component and considered at the
calculation of the Performance Level.
5.1.8 Indicating functions
The anti-collision shall be designed with indicating devices to inform the crane operator (see 6.8) and the
jobsite environment (see 6.9).
5.1.9 Operating computation
To manage potential interfering parts and/or entering in prohibited zone, the anti-collision device
computing shall take into account all the relevant parameters, e.g. accuracy of sensors, control system
response time.
5.2 Information requested to operate the anti‐collision device and system
5.2.1 General
Information provided by sensors which may be part either of the anti-collision device or of the tower
crane shall fulfil the requirements of this document.
Depending on the design of the ACS respectively the ACD, some

Die Norm SIST EN 17076:2021 beschäftigt sich umfassend mit Sicherheitsanforderungen für Antikollisionssysteme, die an Turmdrehkranen installiert sind. Der Anwendungsbereich dieser Norm ist klar umrissen: Sie legt die essentiellen Anforderungen für Antikollisionsgeräte und -systeme fest, die darauf abzielen, Risiken von Kollisionen zwischen mehreren im Einsatz befindlichen Kranen, zwischen einem Kran und festen Hindernissen sowie mit verbotenen Zonen zu vermeiden. Dies ist von zentraler Bedeutung für die Sicherheit und Effizienz auf Baustellen, wo mehrere Krananlagen gleichzeitig genutzt werden. Eine der Stärken dieser Norm ist die detaillierte Definition der Sicherheitsmerkmale und Anforderungen an die Antikollisionssysteme, die speziell für selbstaufstellende Turmdrehkrane und Turmdrehkrane, die aus Teilen montiert sind, vorgesehen sind. Die Norm behandelt unter anderem den Leistungsgrad dieser Systeme, die Informationen, die von den Sensoren geliefert werden müssen, sowie die Betriebsmodalitäten, insbesondere im Falle eines Ausfalls der Systeme. Die Beschreibung der Kommunikationsarten zwischen den Geräten sowie die Informationen für den Kranführer und die Außenanzeige sind weitere wichtige Aspekte, die zur Benutzerfreundlichkeit und Sicherheit beitragen. Ein weiterer bemerkenswerter Punkt der Norm ist die Festlegung von Anforderungen für die Kennzeichnung des Geräts oder Systems sowie den Inhalt der Gebrauchsanweisungen. Dies fördert eine ordnungsgemäße Implementierung und Nutzung der Systeme, wodurch das Risiko von Missverständnissen und Fehlbedienungen minimiert wird. Die Norm identifiziert auch wesentliche Gefahren, die in Abschnitt 4 behandelt werden, sodass Anwender gezielt auf mögliche Sicherheitsrisiken hingewiesen werden.
