Utmost control of stability conditions
Fassi has developed the FSC “Fassi Stability Control” systems, available in different versions specifically designed for each type of crane, to best comply with Machine Directive 2006/42/EC and to apply the corresponding technical standard EN 12999:2011, which requires cranes which have a lifting capacity of at least 1000 kg or a lifting moment equal to and above 40000 Nm to be equipped with vehicle stability control in the safety function carried out by the lifting moment limiting device.
These systems differ according to crane models and respective configurations. In particular, the S (Super) version, featuring fully automatic management and which is installable exclusively on cranes equipped with FX500 or FX900 (ph. A) electronic device, RCH, RCS or V7 RRC radio control (ph. B) and hydraulically-extendable outriggers, is a completely innovative product from an engineering and functional standpoint, and consequently worthy of a thorough and in-depth description.New technological opportunities, innovative spirit and regulatory drive are the main factors that represent the cornerstones of the Fassi Stability Control system. This is why Fassi’s technology, in addition to satisfying new regulations issued by the European regulatory body (CEN), takes into account the various particular features of the range, offering a system with different executions depending on the crane models. This electronic system significantly improves crane control conditions, thus making it easier to use the crane. By working with Fassi cranes in safe conditions, you can be sure to have excellent versatility of use, combined with the best lifting capacity.
The FSC system automatically limits crane operation in the event that all conditions needed to ensure its stability are not satisfied: extension of the lateral supports and positioning of the outrigger rams. This is done through two devices: the proximity sensor (ph. C) for verifying the support on the ground of the outrigger rams and the encoder/micro-switch (ph. D) cable reel that detects the exit of the lateral extension support.The operator is in the position to monitor every step. Information about crane status and the authorization to use the crane once stabilization has been achieved are shown on the radio control display and on the user panel display on the crane.
Versatility
With the FSC/S and FSC/SII versions, if the working positions of the outriggers’ lateral extension supports and the tilting angle of the crane base are found to be unstable, an automatic decrease occurs in terms of the rating of the crane’s performance, the lifting moment limiting device is activated and the working speed is reduced.
Control as well as improved efficiency
Compared to other systems, the Fassi FSC/S and FSC/SII versions introduce more sophisticated safety management: it carries out a double stabilisation check by verifying the position of the outriggers’ lateral extension supports and of the base tilting angle thanks to a tilting sensor with double XY axis (ph. E). As a whole, the system is highly versatile, and it always prioritises and ensures the highest crane performances under conditions of total control.
