Already in 2012 the building of the tunnel with around 6 km length – which is part of the project Hong Kong-Zhuhai-Macao Bridge – started. The Second Engineering Company of CCCC Fourth Harbour Engineering Co. Ltd. is working on this project. For the tunnel with a total length of around 6 km, concrete segments have to be precasted, this means in total 33 segments with 180 meters length each. , and 27,000 m³ concrete per segment.
Also present: Around 100 Wacker Neuson internal vibrators of the model IRFU65, which are constantly in use. Especially the workers on the construction site prefer to use the internal vibrators from Wacker Neuson as the hand-arm-vibration in much lower as it is of competitive machines. The internal vibrators are part of the broad product range of concrete technology in which Wacker Neuson has achieved core competency and brings decades of experience with it. As early as the 1930s, the company identified professional concrete compaction as a potential strategic business segment. Today, internal vibrators from Wacker Neuson are the best-selling worldwide. And safety as well as performance are more important than ever.
The high-frequency internal vibrators of the IRFU series with a built-in frequency converter are characterized by the simple connection to the single-phase mains supply and are immediately ready for operation. Reliable operation, even with generators and fluctuating input voltages, is therefore also possible. Their high wear resistance is guaranteed by the induction hardened vibrator head.
