Tower Cranes
Advanced control systems on Liebherr tower cranes include active assistance systems, which automatically prevent a diagonal pull when lifting the load, reducing operating errors and improving safety.
remote access capabilities that allow technicians to diagnose issues before they begin their travel to the crane.
Scholz noted how advanced control systems enable simple and efficient operation.“ This also includes active assistance systems, which automatically prevent a diagonal pull when lifting the load,” he related.“ These technologies reduce operating errors and improve safety and efficiency.”
In the next couple of years, we can expect all tower cranes to shift to programmable logic controller( PLC) systems, related Patton.“ This transition will enhance control and precision in crane operations, reducing human error and increasing overall safety,” he said.“ Anticollision systems, which prevent cranes from coming into dangerous proximity with other equipment or structures, are also improving safety on jobsites.
“ Modern tower cranes are also being equipped with advanced sensors and zoning systems that provide real-time data, ensuring cranes operate within safe limits,” Patton continued.“ These systems can monitor weight, load distribution and crane movement to prevent overloading and minimize accidents.”
Using a common crane control system( CCS) across tower crane models means all of their top-slewing tower cranes will have the same controls and operational feel, noted Calaman.“ CCS-equipped cranes will also have a similar electrical architecture, making it easier for technicians,” he added,“ while telematics provide the ability to troubleshoot a crane from anywhere.”
Market Outlook
With the use of tower cranes increasing in several project-related areas, Scholz related that Liebherr has a positive market outlook.“ The tower crane market was at a weaker level in 2024 due to very high material and construction costs, as well as high interest rates,” he said.“ For 2025, we see at least a better year due to falling interest rates.”
“ The tower crane market this year is showing signs of positive momentum driven by improving economic conditions,” said Patton.“ These changes contribute to a more favorable investment climate. Infrastructure projects
Wolffkran has incorporated an optimized jib design in the new WOLFF 8038 model. The smart jib features a top chord that can be assembled with a simple plug connection without the need for a hammer, smoothing transitions and facilitating precise load positioning. continue to be a major source of demand for tower cranes along with industrial construction in certain regions. The long-term nature of these projects makes tower cranes a better investment compared to cranes that may be needed for shorter durations.”
Part of what’ s driving orders for tower cranes, noted Calaman, has been a shift toward larger machines on jobs with heavier loads that need to be lifted at longer radii.“ Another advantage these larger cranes offer is that they can often replace two machines on a jobsite,” he added.“ A centrally located large tower crane has the capacity at longer radii to make heavier lifts that traditionally would have required two smaller tower cranes to complete.”
Kohler views 2025 as a transition year.“ As interest rates decline, more developers will either re-start or start projects, increasing the need for tower cranes,” he said.“ In addition, many companies are now requiring employees to return to work, which should lower office vacancy rates and increase demand for office space.”
Overall, the tower crane market appears to be on the upswing, thanks to a combination of improving economic conditions, technological advancements and increased demand among customers for these machines.
