When it comes to heavy infrastructure, some jobs require more than just raw power—they require synchronization. For many complex projects, crane hire is often the best solution to get the job done efficiently and safely.
We recently managed a critical installation involving several 100,000-litre self-bunded diesel tanks. These units are the giants of the fuel storage world. At over 12 meters long, they present a unique logistical challenge. To get them into position safely and accurately, we deployed a Dual Franna Lift strategy for this crane hire project.
Why Use a Dual Franna Lift?
While a single large slewing crane can often handle the weight, the Franna (pick-and-carry) crane offers unmatched maneuverability on busy industrial sites. By using two Frannas in tandem, we gain several key advantages. For those comparing options, crane hire also provides flexibility across different site demands.
- Superior Load Control: With a hook at each end of the tank, our operators have total control over the pitch and yaw of the load. This prevents the “pendulum effect” common with single-point lifts.
- Walking the Load: Unlike static cranes, Frannas can travel with the load. This allows us to offload from transport and “walk” the tank directly onto its concrete footings, even in tight spaces.
- Reduced Site Footprint: Dual Frannas often require less setup space than a massive 100-tonne slewing crane with outriggers. This keeps the rest of the site accessible during the install—a key benefit for crane hire on active projects.
Precision Engineering & Safety
A dual lift isn’t just about having two great operators; it’s about communication. Our team utilizes dedicated dogmen and radio links to ensure that every centimetre of movement is mirrored between the two machines. When planning any manoeuvre, crane hire specialists pay close attention to the details.
For these 100kL tanks, the centre of gravity is critical. Our rigging team calculated the exact sling lengths and capacities required to ensure the tank remained perfectly level throughout the transition from the trailer to the ground. This is something easily managed on site when using crane hire for the task.
The Result: A Seamless Installation
By opting for a dual-lift approach, we reduced the total installation time per tank. This ensured the client’s fuel farm was ready for commissioning ahead of schedule. Whether it’s massive fuel storage or complex structural steel, our team prides itself on finding the most efficient lifting solution for the environment. We often rely on strategic crane hire.
