Production of Large Concrete Products with Vertical Vibration

The demand for larger concrete pipe and box culvert is increasing all over the world and more and more different shapes are used for storm water drainage, sewers, engineering tunnels and walkways. Traditionally these products have been manufactured by wet casting, which gives a nice looking product but decreases the production capacity and raises the cost for casting equipment. The vibration tables produced by HawkeyePedershaab today are from a technological point of view far beyond from the most well known types where a steel construction are suspended by a number of rubber buffers or steel springs, equipped with one or several unsynchronized motor vibrators.
