The performance and the excellent power-to-weight ratio of the Fassi F1450R-HXP Techno are the result of a series of innovations, such as the digital control system, the new display interface, the brand-new stability control, the decagonal design of the secondary arm and extension booms, the new dynamic lift control and above all the new levels of performance.
Fassi is no stranger to anticipating the needs of its customers and proposing innovations that have left their mark on the history of lifting, such as the evolution in safety systems; first electro-hydraulic, then electronic, analogue and most recently digital. This constant development has led to the creation of the Fassi F1450R-HXP TECHNO, the first model in the new TECHNO range equipped with innovative electronics and the FX990 control unit. The combination of mechanical and electronic innovations applied to the crane allows greater control of stability zones, which translates into the ability to work in a vertical position with higher performance. In concrete terms, the vehicle will be able to move closer to the site of intervention, thus occupying less space while lifting more weight.
In addition, dynamic control of the movement speed for handled loads has been increased thanks to a new processing system that has improved management of working area use, favouring lifting capacity. The new decagonal design for the extension block has also contributed to an improvement in vertical performance and the hydraulic circuit, with double feed, has enabled faster handling. The advanced digital control system, the new display interface, the possibility to command stabilisers via radio controller and the new trim further optimise performance. Lastly, the system of folding pulleys on the winch, the possibility to add the new Fassi L82 jib and the excellent power-to-weight ratio complete the strengths of this revolutionary crane.
Fassi F1450R-HXP TECHNO
With this completely new design, the main objective was to achieve maximum performance in vertical configuration, thanks to the brand-new decagonal section of the secondary block. The structural design of the F1450R is also characterised by a number of Fassi design strengths, such as the use of ultra-high-strength UHSS steels, in-depth kinetic analysis, computerised simulation and FEM finished element analysis, all verified by stress tests carried out on the first prototype.
In particular, the decagonal section, not a novelty for Fassi, having used it five years ago on crane models for the US market, is characterised by increased mechanical performance, motion guides and the inertial stability of vertical loads. The result is that, in comparison to the hexagonal section, lighter solutions can be developed that offer the same mechanical performance, and higher mechanical performance can be achieved with the same weight. In fact, in comparison with previous models in the same category and with the same weight of the secondary group, an increase in vertical performance of more than 50% has been achieved. Furthermore, in order to increase lifting performance, new kinetics featuring a double ram on the main arm and a rotation unit on a new slew ring with dual gearmotor have all been developed.
New FX990 electronics and control unit
The main feature of the new FX990 unit is the significant increase in resources with three CAN-BUS lines; one dedicated to sensors, one to controls and one to vehicle connection. The latter relates to the importance of previous developments, from FX-Link to the DBF (Drive by Fassi) function for the remote control of the truck via the crane's V7 radio controller. In addition, two Ethernet lines further extend connectivity and processing power, another first.
In fact, while CAN-BUS communication is a known standard, the choice of hardware equipped with an Ethernet line makes Fassi the only company in the sector that has identified it as a solution due to its potential. This allows new solutions to be created, from the connection to the FX991 7" colour touch display, to the gateway unit with multi-connectivity for IoC (Internet of Cranes), as well as many more for the future.
The new electronics, or rather the new TECHNO operation and control system, is completed with a new line of sensors that are compliant with the indications of the “Machine Directive” and the upcoming requirements of the EN12999 regulation that will come into force in 2023. All the sensors are manufactured by TSM, a Group company, which - thanks to these new developments - has provided sensors that comply with the EN13849 safety standard and communicate in a secure manner thanks to the implementation of Canopen Safety protocol, which is a reference point for the Techno range.
There are also a wide range of innovations in the software, which are reflected in new crane functions. Important new features include the FSC-SIII stability control system, which is the result of a merging of the performance of FSC-H and FSC-SII. Again, on the subject of stability, another interesting feature is the stabilisation command system via radio controller, which has two operating modes: with a single lever, a new feature, or with a double lever.
The JDP (Jib Dual Power) function is now automatic; the limiter is able to recognise the conditions in which the crane is being used, automatically providing the best performance of the hydraulic extension. In order to satisfy the various requirements of operators, the function can be manually activated or disabled from the radio controller.
Thanks to the geometric monitoring of all the crane's articulations (main arm, secondary arm and extension arm), the approach to the mechanical limit of the relative ram will be managed in a "soft" manner through progressive deceleration in the last millimetres of travel. By managing movement, this new function, named SoftTend, will allow for an increase in speed while eliminating the dangerous development of load-swing caused by an abrupt stop against the mechanical limit switch. Compartmental working areas can also be created, increasing safety and releasing the operator from having to monitor these zones for possible interference, allowing them to better focus on handling the load.
Thanks to the new sensors (specifically those compliant with the safety criteria of EN13849) integrated into the new control unit and its safety software, the EN280 standard for crane use with platform or basket is also met. As a result, all cranes in the new TECHNO range are supplied ready for use as personnel-lifting cranes with regards to stabilisation.
The Ethernet connection has allowed for the integration of various devices, such as the new FX991 display, which also features new, more comprehensive and intuitive graphics, and the new gateway ensuring more powerful connectivity to the crane. The IoC (Internet of Cranes) system is combined with an external GPS/GSM antenna for better reception and uses a new portal, with a completely revised graphic interface and functions. The new gateway is also equipped with a wi-fi module which, by creating its own network and access address, allows the crane to be connected to various operator devices (PC, tablet or smartphone).
The entire processing system based on the new connectivity has the main function of managing data and providing information with which to create new technological architectures which are of value to both the customer and the system itself. The most important include maintenance, a fundamental process in guaranteeing the correct functioning of the crane, operator safety and the maintaining of the crane’s value over time. These three reference points have formed the basis on which the DMA (Dynamic Maintenance Assistant) function has been developed, which can be accessed immediately either via the radio controller display or from the FX991 on-board display, as well as via a smartphone for cranes fitted with IoC. This function uses graphics to provide a dynamic presentation, i.e., in accordance with the actual use of the crane, of how many hours remain until the next service. This means that downtime can be scheduled at the most opportune time and in accordance with the customer's work requirements.
