several cranes in service, to avoid the risks of collision between a crane in use and fixed obstacles, and to
avoid travelling over prohibited zones.
It also specifies the requirements for working range limiting devices.
Anti-collision devices and systems and working range limiting devices according to this document are
safety components.
This document defines the safety characteristics and requirements of anti-collision devices and systems
intended for installation on self-erecting tower cranes and tower cranes erected from parts.
In particular:
— performance level;
— information to be provided by the sensors installed on the crane;
— operation, particularly in the event of failure, override and free jib slewing states of a crane;
— type of communication between devices;
— information for the crane operator and outside indicator.
This document deals with all significant hazards, hazardous situations and events relevant to anti-
collision 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;
— 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.
14
---------------------- Page: 16 ----------------------
SIST EN 17076:2021
EN 17076:2020 (E)
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 or all of the information given in 5.2.2 to
5.2.6 shall be provided.
Such information shall comply with the requirements given in 5.2.2 to 5.2.6.
NOTE The accuracy includes all errors combined due to the accuracy of the sensor and the inaccuracies of the
driveline.
5.2.2 Updating time
For the smooth operation of the anti-collision device, the information provided by the sensors shall have
a maximum updating time of 200 ms.
5.2.3 Crane response time
The anti-collision device shall be designed to operate with a crane designed to have a maximum response
time of 500 ms.

Following information shall be available for the anti-collision device:
— the crane control is powered on;
— the crane is in free slewing mode;
— crane motion control ordered by crane operator (e.g. joystick position, direction of motion(s)).
When it is possible to disengage an anti-collision device from the crane, this information shall be provided
to the anti-collision device.
In addition, when the crane is operated by cableless control, this information may be provided to the anti-
collision device.
5.2.5 Crane position information
In addition to the specified accuracy values given in Tables 2 to 6, the anti-collision device shall take into
account the effects of deflection and swinging of the crane structure disregarding the possible swinging
of the hook block and the load volume that needs to be considered in the setting (see 9.3) and the
computation (see 5.1.9) of the anti-collision device.
— Slewing angle position
The slewing angle between the fixed pivot and the rotating pivot shall have the capacity to be
assessed at 360° with the characteristics given in Table 2.

e.g. dimensions of interfering cranes, site layout.
It shall be possible to set the safety distance in the ACD (see 9.3).
5.3 Requirements for controls of anti‐collision devices
In all relevant crane motions it shall be possible:
— to order the stop of the movement according to the crane manufacturer instructions (e.g. at slewing
motion it could be made by deceleration using counter torque or using brake);
— to order a lower speed, if available;
— to order the emergency stop of the tower crane.
5.4 Additional requirements
Anti-collision devices shall be designed to comply with EN 60204-32:2008.
