The World Is Turning to MOBA Big Sonic-Ski System - Page 3 of 3
MOBA technology enabled rehabilitation of major city highway that could only be closed at night in the city of Cairo, Egypt.
Ultrasonic system for maximum planarity
Thanks to the MOBA-matic levelling system with the Big Sonic-Ski that the construction company, General Nile Company for Road Construction (GNCRC), used on both sides of a Terex CR462 paver, it was possible to lay the asphalt quickly and precisely.
The Big Sonic-Ski is a combination of up to four ultrasound sensors attached to a flexible 13 metre long mechanical system.
All of the sensors send their measurement values to the MOBA-matic which calculates an average value. This means that even long sections of unevenness can be detected and smoothed out during laying the asphalt by means of automatic adjustment of the screed.
Fast And Exact Asphalt Paving
With this solution, it was possible to avoid complete closure of the motorway. By allowing the pavers to only work during the night, the effect on the traffic was minimised.
Mohamed Saaied, Head of Technical Sector GNCRC explained:
With the Big Sonic-Ski, it was possible to smooth out the unevenness without problem and to lay an extremely level and uniform asphalt surface.
The only possible alternative to the Big Sonic-Ski would have been to use a levelling system in combination with a string line as reference because the kerbstone had too many holes and was too uneven to be used as a reference.
Furthermore, surveying using a string line would not only have been expensive and more time-consuming, it would also have made it necessary to close the road, which, in view of the traffic situation, was impossible. This is why the customer opted for the MOBA levelling system MOBA-matic with the Big Sonic-Ski.
Hafez Abdelmoamen, chairman GNCRC said:
We are extremely pleased with the accuracy of the system and that the system is so easy to use and the Big Sonic-Ski provided an added bonus: The safety lamps, which are required for work at night, could be easily mounted on the mechanical system.
Hesham Farghaly, managing director of Egyptians Engineering, MOBA partner in Egypt reinforced this:
We are not only one of the biggest road construction companies, but also one of the pioneers in using new technologies in this sector. That is how we can get the best results in road construction.
In Egypt, the use of new technologies is, as it were, still in its infancy. Such projects are important as they demonstrate the benefits – and these benefits are not only evident in the perfect road surface but are also illustrated by the fact that savings in time and material were achieved. And that it was possible to use the machine more quickly for other projects.
