Mobile port crane offer flexible solutions for cargo handling in ports, from container handling, to
bulk products management and heavy cargo handling
Fantuzzi Reggiane MHC mobile port crane, in different models and load capacities, allow to meet
all the needs required by the market.
Their robust mechanical structure and the complete optimal movements control with the use of
hydraulic motors (hoist, rotation, boom and translation) make them particularly flexible machines
and particularly interesting in cranes global market
Crane original control system is entrusted to a specialist electronics, managed by a master-slave
structure microprocessor, which uses input/output remote peripheral terminals and specialized
terminal operators
Control system heart consists of a management computer, so-called Monitor, on which software is
visible, realized in "C" pseudo language, for crane management; such a software is not accessible
to the end user
Although they are reliable mobile cranes and present on the market for years, but now out of
production for some time, there is the problem of spare electronic components become unavailable
and in particular of the control part, consisting of:
•
Monitor complete with operator panel, is made up of custom microprocessor equipment
that manages crane automation
•
Electronic Keyboard (one or two keyboards in function of the presence or absence of the
second operator's cab) with on board main command buttons for the operator
•
Mobile Button Panel, for Jog commands for crane working at low speeds.
•
Slave, input/output peripheral, for signal acquisition and seats activation, mounted inside
the electrical panel
The installation of this opened system of MHC Fantuzzi Reggiane cranes makes the client
independent from suppliers of specific equipment and allows, in fact, reducing downtime and
extending the useful life of the crane: the final client can provide for system maintenance
purchasing equipment on the market directly
Tekna Automazione e Controllo, thanks to its twenty years of experience in industrial automation
using PLC and as a provider of complete equipment for cranes and machines in the port sector for
the leading Italian cranes manufacturers, has developed a new control system based on
Siemens S7 PLC, which is able to replace the original control system of MHC Fantuzzi Reggiane
crane, and that solves the serious problem of unavailability of spare parts, improving the
processing speed and crane diagnostics.
Tekna Automazione e Controllo is able to supply, install and commission the complete system,
with "turnkey" formula, for all models of MHC Fantuzzi Reggiane mobile cranes and anywhere in
the world.

TEKNA AUTOMAZIONE E CONTROLLO CONTROL SYSTEM
MHC FANTUZZI REGGIANE MOBILE CRANE
Tekna Automazione e Controllo control system for MHC Fantuzzi Reggiane mobile crane
automation is made up of an open system based on a standard SIEMENS S7 PLC and Siemens
Operator Panels, replacing the obsolete closed system developed on sophisticated electronics
With the development of its automation system TEKNA Automazione e Controllo wants to provide
to its customers an open system to give them an economic management of MHC Fantuzzi
Reggiane crane maintenance, features restoration time reduction after a fault and to delete the
existing monopoly for spare parts supply
CONTROL SYSTEM STRUCTURE
The used P.L.C. is Siemens S7-300, with a central rack (that replaces the Monitor of the current
system) and remote racks ET200 for input/output management (that replace the SLAVES of the
current system). The central and remote rack are configured and planned to be installed inside the
existing cabinet and in the same positions of the Slaves, after their removal
The supply includes, in particular:
•
A pre-wired plate, with the main PLC rack S7-300 on board and other electromechanical
equipment, which is installed inside the existing electrical panel, in the position currently
occupied by the current system SLAVE
•
An ET200 remote rack, wired inside the button panel to be installed in the operator's cab.
The new button panel, included in the supply, fully replaces the existing one, and replicates
all the controls and alarms using buttons, lamps and industrial selectors. On the button
panel board is installed, in addition, stabilizers joystick
•
A second remote rack ET200, wired inside a control panel perfectly identical to the one of
the previous point, to be installed in the lower operator's cab, if present
•
A third remote rack ET200, wired into the button panel for the JOG commands, attached to
the connector on the side of the cabinet. The JOG button panel, included in the supply,
completely replaces the existing one, and replicates all the controls and alarms using
buttons, lamps and industrial selectors.
Profibus-DP net connects P.L.C. to remote ET200 units: the supply includes the cable, its
installation and its connection
The new automation system, with its interface cards, is perfectly compatible with the sensors
installed on crane board, such as pressure switches, pressure gauges, load cells, encoders,
manipulators, etc.., and doesn’t require, therefore, their replacement

OPERATOR INTERFACE
User interface has been implemented using standard industrial Operator Panels, color Touch
Screen size 10 "or 12"
Operator panels are installed inside the cabins and allow to manage all the machine functions,
from parameters setting to crane diagnosis.
Profibus-DP net connects P.L.C. to remote ET200 units: the supply includes the cable, its
installation and its connection
Additional features have been implemented compared to those on the current Monitor, and in
particular:
•
crane diagnostics has been enhanced by useful additional information that help to reduce
time troubleshooting
•
video pages have been implemented to duplicate commands on the button panel operator:
the operator, acting directly on the touch screen monitor, may require all the commands
implementing without using the button panel
•
video pages have been implemented to display if the conditions that enable the movements
are active; such information are very useful to quickly identify the causes of crane nonoperation

SUPPLY, INSTALLATION AND COMMISSIONING
CONTROL SYSTEM IMPELEMENTED IN SIEMENS S7 P.L.C.
Crane automation is carried out by a specialized electronics, controlled by a microprocessor with a
master-slave structure, which use remote input/output units and specialized operator terminals,
obsolete and hard to find on the market
The system developed by Tekna Automazione e Controllo provides for the replacement of obsolete
equipment with new commercial one such as Siemens S7 PLC and market operator terminals,
complete of specific software for crane automation
