Combining technologies leads to safer, more efficient crane

03.03.2005


EUREKA project E! 2797 FACTORY MSETC (Mobile Self-Erecting Tower Crane) has successfully combined the technologies of mobile and self-erecting cranes to create a single crane that can do the work of five. The new crane features an anti-sway device which makes it safer as well as more efficient.

The Belgian lead partner, Arcomet NV, has developed self-erecting tower cranes for the building industry for many years. “These cranes were mounted and remained in a fixed position on building sites for at least three months, when they were only needed for a total of about five hours work. Since a construction job may require cranes to be at different parts of the site, this was very expensive,” explains Project Manager David Janssen.

The project partners devised new mobile self-erecting cranes that can be delivered on a truck, erected on site within a small area, and moved to new locations as and when required. This one crane can do the work which previously required several installations. “To develop such a crane, it was necessary to combine knowledge of how self-erecting cranes and mobile (hydraulic) cranes are developed. By combining the know-how and development efforts of each partner, the time-to-market was minimised,” says Janssen.



The project also had to redesign the truck or loader, and a crawler for use in particularly rough terrain, making the chassis lower and more stable so that it could be delivered to all parts of a building site. They also developed a new anti-sway system that makes the installed crane safer and more efficient. “We developed an anti-sway controller that minimises or completely prevents the sway motion of the load during operation,” says Dr Jans Swevers of the University of Leuven.

“The device controls both the rotating (boom) motion and the motion of the trolley. Each aspect is independent of the load that is lifted, and the anti-sway controller adapts its parameters according to the length of the cable, taking into account the structural resonance of the crane. The controller was designed so that even an inexperienced operator can move loads safely without them swinging,” explains Swevers. “The crane does not require additional sensors to detect sideways movements, it reduces the sway motion by a factor of three, and it is guaranteed to give stability to a degree that no additional safety measures are required.”

Thanks to EUREKA, the partners are ready to target new and existing markets throughout Europe. They already have orders for 15 of the new cranes. “Working with our partners through EUREKA enabled us to create the new technology in a shorter time,” says Janssen.

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
