The FSC/S system is factory-fitted for the crane range from model F245A dynamic/e-dynamic up to model F1950RA he-dynamic. It can be installed, as on option, on all the other crane models that they are equipped provided with FX500 or FX800, RCH/RCS radio control and hydraulically extendable outriggers. The system detects the right and left work areas of the vehicle and automatically manages the lifting moment limiting device for two work areas: above the cab and above the body, the existing stability on the two sectors permitting. In both sectors, the lifting limiting device system starts working on its own based on the position of the outriggers lateral extension supports (closed, partially or fully extended) verified by means of the linear encoders. Moreover, a tilting sensor that measures the horizontal position of the crane with reference to the inclination of the crane base crossbeam, everything managed by dynamic software, limits crane performances and protects the different working configurations with respect to the sector the crane is in, the outriggers position/extension and the inclination of the crane base. When the outriggers are not fully extended, the lifting moment limiting device activation pressure is recalculated and reduced and, according to the position of the crane arms, there may be a reduction in the working speed. The additional crossbeam, on the other hand, is managed for fully extended or retracted or partially extended outriggers if the additional crossbeam has double lateral extension supports. Moreover, the system can automatically read the effect of a possible counterweight and the presence of additional outriggers in addition to the ones foreseen.
