For all models fitted with stability control system FSC-SII.
The FSC-SII system in conjunction with HS supplementary outriggers converts the available truck stability into maximum lifting capacity from 25% outrigger extension. To safely achieve this high level of performance the crane must be stabilised within 2 degrees of the truck starting slope. If not the FSC-SII system will automatically reduce the lifting capacity to a safe fixed level on the downhill side to prevent truck instability.
