Electric concrete internal vibrator

Pneumatic inner vibrators are used on different moulds or those where fixed external vibrators cannot be used, either because they are unsuitable or because it is not possible to attach them. They are also used when the specifications require particular qualities of concrete, especially on large-scale items and when application of external vibrators is insufficient to obtain optimum vibration. Inner vibrators are used, in particular, on bridge piers, viaducts, supporting walls, dams and in any situation where specific qualities of concrete are required and core boring is used to carry out resistance tests on castings.
