Endagered species protected by external vibrators

The Tasmanian devil is in danger of extinction due to a facial cancer (DFTD) that only occurs with Tasmanian devils and spreads very quickly. Today, the mammal can only be found on the island of Tasmania, Australia. The Tasmanian devil is named by the way its ears turn red when excited. In an attempt to save the animals, external vibrators from Wacker Neuson are being used.


Action has already been taken against the further spread of this disease for several  years. The most effective method is to isolate the non-infected animals and therefore

protect them from the disease. In the wild, large areas are fenced in for this purpose in order to prevent contact with the diseased devils. To nevertheless have open access for vehicles, cattle grids were installed in the roads at some points. The clever Tasmanian devil can, however, cross this cattle grid on its tiptoes. 

In order to prevent this, external vibrators from Wacker Neuson have been in use for some time, which are normally used for concrete compaction. The external vibrator is attached to the cattle grid at the entrance of the enclosure. Using an infrared transmitter that reacts like a motion detector, the external vibrator is activated and starts to vibrate. The vibration on the grate makes noise, which scares the Tasmanian devils and makes them want to get away. This simple but effective method contributes to the protection of the endangered species. 

In actuality, external vibrators are primarily applied in precast concrete parts plants and on construction sites where narrow or specially shaped concrete parts are created. They are attached externally to the formwork and generate a vibration, which transports the air in the freshly mixed concrete to the surface and ensures for a higher density. External vibrators from Wacker Neuson are characterized by a long service life.
