Franna AT 40 Specifications

The  Franna AT 40 pick and carry crane has a huge maximum lift capacity of 40 metric tons (44 USt), the crane boasts 44% more load moment than the MAC 25. No need for a removable counterweight with this 3-axle design and the third axle control system raises the 3rd axle when operating on a job site, providing a similar turning radius as the MAC 25. Maximum road speeds of up to 75 km/h enable the crane operator to move quickly and safely to and from each job site. 

Includes a full-width isolated cabin, articulating counterweight, and increased cabin storage.

Dynamic LMI (Patent Protected)

Franna’s patented Dynamic LMI remains a pillar of safety, 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 utilization 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.

Other operational aids include:

• Operator settable maximum working height
• Maximum working radius
• Percentage of rated capacity

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