The MAC 25-4 is a mobile articulated crane with a maximum lifting capacity of 25 tonne (27 USt). The MAC 25-4 offers maximum safety, excellent roadability, intuitive operation and unmatched versatility. Over the years it's design has been tried, tested and proven in a range of difficult lifting applications and is still a customer favourite today.
A superlift (SL) upgrade is also available on the MAC 25-4 as an additional option. The SL kit works in tandem with the existing MAC 25 counterweight, adding a low slung additional counterweight piece to the rear of the machine, increasing rated capacity of the machine up to 30% in some configurations.
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).
