Millimetre precision for a Ferris wheel assembly

When space is tight and precision leaves no room for error, choosing the right machine makes all the difference. That is what Top Noleggio demonstrated in a recent job, where two knuckle boom cranes from the Tadano PM made it possible to assemble a Ferris wheel under particularly challenging logistical conditions.

Italian rental company, Top Noleggio, provided equipment  which supported the assembly of a Ferris wheel through the lifting and positioning of various structural components. The challenges were significant: limited operating space, narrow access routes, and logistical conditions that ruled out the use of a conventional mobile crane.

“The main difficulty was the restricted jobsite,” the team explains. “Access was tight and the overall setup did not allow us to operate with a traditional crane solution.”

Top Noleggio, operating a fleet of over 500 units — rose to the challenge with two machines from its lifting fleet: the PM 100SP and the PM 150SP from the Tadano PM Series.

The tandem deployment of the two machines allowed the entire assembly process to be managed with the necessary safety and precision. The PM 100SP and PM 150SP worked in sync, effectively compensating for the constraints imposed by the site and ensuring smooth operations throughout the job.

“The use of two cranes was essential, as the site conditions did not allow efficient operation with just one machine,” the team reports. “This setup enabled us to complete the assembly safely and with the required level of accuracy.”

Outreach and tip capacity were essential – two defining strengths of the Tadano PM Series that turned a complex challenge into a successful operation.

One of the most critical aspects of the operation was the alignment of anchor pins and structural components of the wheel – movements that had to be, literally, millimetre-accurate.

In this context, the radio remote control proved invaluable. It allowed operators to position themselves right next to the structure and monitor every single movement up close, maximising both precision and safety during the most delicate phases.

“The movements had to be extremely precise – almost millimetric — to ensure proper alignment of all structural components,” the operators emphasize. “The radio remote control was a key tool in achieving this level of accuracy.”

No issues were reported during the project. The cranes’ manoeuvrability and precise control significantly impacted the positioning of the Ferris wheel components, making the process faster, safer, and more efficient.

“The cranes performed excellently during all phases of the job. We did not encounter any critical issues and were fully satisfied with the result,” the team confirms.

The project was completed successfully: the Ferris wheel was correctly assembled and made fully operational, on schedule and without any complications for the client or the operators involved. The client’s satisfaction – both with the execution time and the quality of the work – is the clearest confirmation of a job well done.

“After this experience, we confirm our full confidence in Tadano PM cranes for similar projects.”
