The year 2025 is seeing a strong resurgence in high-rise construction across Asia, North America, and the Middle East, leading to rapid expansion of tower crane fleets worldwide. According to CTBUH’s 2025 Q1 report, more than 150 new towers above 200 meters are under construction globally, with notable activity in Singapore, Riyadh, Shenzhen, Seattle, and London.

Tower cranes rely on slewing rings and rotation mechanisms to support continuous 360° rotation during lifting operations. Rental companies report higher utilization rates and increased orders for cranes with improved slewing-ring lubrication systems, enhanced rotation stability, and more accessible maintenance platforms.

Several cities have announced major redevelopment initiatives—such as Saudi Arabia’s continued megaproject expansion, Singapore’s transport corridor upgrades, and multiple U.S. urban residential towers—that require long-duration crane deployments. This boosts demand for reliable rotational systems that can withstand months of operation under variable wind and load conditions.

The tower crane market growth in 2025 underscores the essential role of robust slewing systems in meeting global urban development needs.
