TRANSCRIPT
The risks associated with the use of tower cranes on jobsites - collisions between cranes,
collision with high voltage electricity lines ect… - may have serious consequences
As a solution to these problems, SMIE has developped the technology for anticollision and
zoning systems for all jobsite situations.
AC246 – Anticollision in motion
The AC246, the latest generation of zoning anticollision systems developped by SMIE,
category 2 according to the norm EN954-1, is the fruit of an unequalled experience of more
than 20 years acquired through thousands of installations throughout the world. These sys-
tems meet the high requirements of the European norm EN14439.
Zoning________________________________________
This function prevents the over-sailing of critical zones and of
static obstacles (high voltage lines, railway lines, public pla-
ces, schools, etc…)
The crane can therefore work in proximity of the zone or fol-
low its boundary in complete safety.
• Can define up to 15 zones
• Definition of zones with lines, circles, arcs or point by
point
• Hook height management by thresholds possible
Anticollision___________________________________
In this case, the obstacle to avoid is another crane (hoist cable,
jib, counter-jib, mast). The obstacle is no longer static but dy-
namic. The AC246 system allows cranes to track each other
automatically at an optimum speed and distance in complete
safety, therefore increasing the productivity of the site.
The AC246 system :
• Measures the position and speed of the load—slewing and
trolley positions.
• Calculates, in real time, the risk of collision with respect to
the breaking capacity of the crane.
• Informs the operator if a collision risk is identified.
• Implements a braking procedure as soon as a collision risk
is identified.
For an anticollision solution, each crane must be equipped
with an AC246 system.
Inter-crane Communication__________________________________________
In terms of communication, AC246 systems offer you the choice of cabled connection (up to 30
cranes on one network) or wireless connection (up to 21 cranes per RAC3 network). For more than
21 cranes, several radio networks can be set up on the same site for inter-crane interference manage-
ment.
Wireless Communication
The RAC radios are specially designed to suit the requirements of inter-crane interference manage-
ment.
Developed around an industrial module, the Rac radio offers an excellent level of frequency stability
for safer communication. Selection by software of up to 160 channels considerably reduces the pro-
blems of interference especially in dense urban areas.
Options
SGC240 — graphical supervising
and recording device
Graphical supervising device for
anticollision operations, the
SGC240 allows the remote moni-
toring of complex jobsites :
• The supervising function offers a
graphical visualisation, in real
time, of the overall operation of
the anticollision systems onsite.
• The SGC240 records informa-
tion relative to anticollision sys-
tems.
• The cartography function im-
proves cranes work and jobsite
organisation thanks to the dis-
play of high activity zones. It
becomes possible to prevent
traffic jams risks, to better or-
ganise teams work or also to
reposition the material storage
areas on the construction site
• The data recorded by the
SGC240 can be consulted remo-
tely by internet and downloaded.

Positive Safety and fault management________________________________________________________________________
This system is capable of identifying a large number of faults in its own operation: internal functions, sensor validity, external
inter-crane communication faults, identification of overrides, free slewing, etc…
When such a situation is identified, all systems involved take the required measures to prevent any dangereous movements
whilst maintaining the maximum freedom of movement.
Partnerships with crane manufacturers______________________________________________________________________
Recognised for their experience and their know-how, SMIE works together with crane manufacturers to develop new systems and
specific anticollision interfaces.
TRAVELLING SENSOR
Provides the information of
the crane position when
travelling on rails.
JUNCTION BOX WITH
2 KEYS
Enables to override the zoning function
of a crane whilst maintaining the anticol-
lision management with other cranes..
UNIVERSAL SLEWING SENSOR
Provides jib/counter jib slewing angle information.
The redesign of the slewing sensor has optimized its
number of parts and, as a result, simplified installation.
This insures a direct and reliable connection between
the slewing sensor of the crane and the encoder. No
more gears, the ratio can be programmed directly on
the central unit.
EXTERNAL SIGNAL LIGHT
Indicates to the site staff if there is a
fault with the anticollision system or if
it has been disabled (overrides, internal
faults etc..).
OPERATOR DISPLAY WITH TEST BUT-
TON
Provides information to the driver on current
state of system free or inhibited movements,
overrides, defects, trolley and slewing position
ect.... One pressure and the panel display to the
driver the checking procedure step by step. A
crane driver sheet is supplied with each AC246
to describe the check points.
CENTRAL UNIT
Central control unit calculates the crane posi-
tion and evaluates the risk of collision with
respect to other interfering cranes on site.
Includes a specific sotware with the system
autotest
MACHINE INTERFACE AND
OVERRIDE DEVICE
The electromechanical machine
interface connects the central unit to
the crane control cabinet. It controls
the different movements of every
type of crane.
WIRELESS COMMUNICATION
Wireless transmission module which
allows the exchange of information
between the cranes.
TROLLEY SENSOR
Provides information on the
trolley position on the jib.
A universal system_______________________________________________________________________
The AC246 system can be adapted on all types of cranes with only minor modifications:
Saddle jib cranes, luffing jib cranes, fixed cranes, travelling cranes, PLC controlled cranes, relay controlled cranes...
