An excavator mounted vibrator is a hydraulic vibrating unit that you fit to an excavator arm in place of the bucket. A powerful hydraulic jaw grips the sheet pile or pile, after which the vibrator makes it vibrate at high frequency. The vibration reduces the resistance of the surrounding soil, so you can push the section into the ground or pull it out.
The EMV range from British manufacturer Dawson has five models, from the light EMV70 to the heavy EMV550. They are built with minimal height, so you can handle the longest possible sections, and with a slim design to drive single sheet piles. A universal joint suspension makes alignment easy, and very little vibration is transmitted to the excavator.
The Dawson vibrators are built for groundworks, foundation, road and marine contractors who install or extract sheet piles, tube piles and H-sections. Because you use your own excavator, no separate piling rig is needed. If you only install sheet piles occasionally, renting is an attractive option.
The key data per model, according to Dawson’s technical datasheet:
Centrifugal force tells you how much force the vibrator transfers to the section: the higher it is, the heavier the sections and the denser the soil it can handle. Clamping force determines how firmly the section is held. The required flow and pressure must match your excavator’s hydraulics; we check this with you before recommending a model.
With an excavator mounted vibrator you work flexibly with your own machine:
We do not publish prices online. Every request is handled personally, because the configuration, options and delivery differ from project to project. This way you receive a quotation that truly fits your work, for purchase or for rental.
The price of a Dawson vibrator depends on the model, and therefore on the size of your excavator, on the clamps and on the hydraulic connection. For rental, the duration of your project also plays a role. We are happy to advise which model suits your machine and your sections.
