FSC-S (variable outrigger position)
A high specification solution offering the maximum possible operational flexibility. FSC-S is standard on the F245A e-dynamic to F1950RA he-dynamic & optional on the F80A e-active to F245A e-active provided the crane has been specified with radio remote control & hydraulically operated outriggers.
FSC-S incorporates encoders to monitor the position of the outriggers & an inclination sensor to monitor the X axis horizontal position of the crane (Y axis is no longer controlled from 2012).
The system is thus able to manage fully variable outrigger deployment positions & incorporate the payload of the truck as a counterweight. The crane rotation is monitored to allow outrigger deployment on one side only.
Why monitor both inclination of the truck & outrigger position?
During the development of FSC, Fassi extensively tested an inclination sensor acting on its own. This was not found to be a foolproof solution specifically in relation to the dynamics of a moving load. When a truck nears the limits of stability things happen quickly, particularly if the crane is working above horizontal.
By measuring the combined outrigger position & truck inclination FSC ensures total safety with much greater operating speed, lifting capacity & tilt than is possible with an inclination sensor on it’s own.
An inclination sensor on its own would also require a very stiff subframe to reduce tilt to safe levels. The extra cross beams required will add over a 1 tonne weight penalty on a 60tm crane installation.
