Dynamic LMI (Patent Protected)

First released in 2013, Franna’s patented Dynamic LMI remains as a pillar of safety, underpinning the electronic control and user experience offered today. The system is designed to offer ‘real-time’ calculation of rated capacity taking into account boom configuration, as well as chassis articulation, pitch and roll, enabling continual assessment of structural limitations, forward stability and side stability. 

Increased resolution of rated capacity is made possible by finer measurement of articulation pitch and roll angles, allowing for improved machine capability compared to previous generation LMI systems. When operated on a jobsite over undulating terrain, the rated capacity will be updated continually, providing instantaneous information on the percentage utilisation of the machine (0-100% of available capacity). When operating on a side slope or undulating terrain, operators are no longer required to manually calculate a reduction of rated capacity; the Franna Dynamic LMI does that.
Key Features:

    Automatic counterweight detection
    Operator settable maximum working height
    Maximum working radius
    Maximum front axle weight
    Rigging limits
    Percentage of rated capacity

These features further enhance the safe operation of the machine when site conditions get tough and are available in retrofit form for all Mercedes powered Franna cranes.
