AT40 mobile crane

The AT40 mobile crane is Franna's latest addition with a maximum lifting capacity of 40 tonnes. It excels with a higher load capacity of 44% compared to the MAC 25. The three-axle design eliminates the need for a removable counterweight. The third-axle control system lifts the third axle when working on site. The maximum road speed is up to 75 km/h, making it fast and safe to move.

Dynamic LMI (Patented):

The Dynamic LMI system provides “real-time” calculation of the rated power. It assesses the structural limits and stability of the machine. Power resolution is improved thanks to more accurate tilt angle measurement. When working on rough terrain, the rated power is continuously updated. Franna Dynamic LMI automatically adjusts the power reduction.

Main function:

• Maximum working height set by operator.
• Maximum working radius.
• Rated power ratio.

These features make the machine safer to operate in difficult conditions. Upgrades are available for all Franna cranes with Mercedes engines.
