Excavator Mounted Piling Vibrators, are small pile drivers, available for hire. These V vibrators operate through a combination of the powerful vibrations produced by the attachment and the crowd or push-force of the excavator to which it is attached. It is a relatively new format for an old technology, as piling using vibration has been the main means for sheet pile installation for decades. However, this format has revolutionized the way plastic Sheet Piling and trench sheet is driven.
In general, Vibrators are much quieter than impact hammers, In granular soils; which fluidise under the influence of the vibration, Vibrators can obtain installation speeds many times faster than impact hammers. Piling Vibrators differ from compactor plates, as they apply a bi-directional force (up and down) to the pile. Also, force tends to be much higher and better focused as the vibration mechanism consists of two eccentric weights that act to reinforce the vertical vibratory force (the useful stuff) and cancel out vibration that would occur laterally. Compactor plates tend to have a single eccentric and so vibrate as much forward and backward as they do up and down.
