Major technical project with international appeal

The new flagpole reaches an impressive height of 190 meters, replacing the previous 162-meter tower, which was dismantled in 2018. It stands in the heart of Baku Boulevard, right on the shores of the Caspian Sea – a vibrant area with numerous attractions such as the Park Bulvar shopping center, the Baku Ferris wheel and the city’s first open-air cinema.

The project was characterized by close cooperation between ITH and local partners right from the start. Initial talks with a Turkish crane manufacturer took place back in 2020. The new flagpole was successfully completed in August 2024 – a milestone for everyone involved.

Customized bolting technology for maximum safety

The flagpole consists of ten tower segments, which were connected to each other via nine flange connections. The innovative ITH stretch method was used, with which all flanges (except the foundation flange) were connected with high precision. The segments were manufactured in Turkey and then assembled in Baku.

ITH developed three-stage Bolt Tensioning Cylinders for this project, which enable high preloads even with limited space. Pillar cranes were also used for simple handling. Pumps with a customer-specific PD system were supplied to document all bolting processes.

Among other things, the following were used:

ITH-SSZ in sizes M100, M80, M60, M48 and M30
ITH battery-powered nut runners ADS with adjusting socket (150 – 500 Nm)
IHF Studbolts and IHF Roundnuts

Efficiency in assembling: ITH develops special components

A highlight was the U-shaped mounting sleeve in half-tube form, which was specially developed for this project and allowed the IHF bolts to be positioned quickly and precisely. The double-row bolt arrangement provided additional stability and excellent structural integrity of the mast.

ITH employees Thimo Schauf and Makhmud Guseynov accompanied the project on site and ensured continuous quality controls. The mast was also checked again 500 hours after installation – all bolts were retightened.

The project in Baku impressively demonstrates how ITH applies its expertise in large-scale international projects. With experience from similar projects – such as the flagpole in Sheboygan, Wisconsin (USA) – ITH once again confirms its leading role in industrial bolting technology and connection technology worldwide.
