MOOSER Pneumatic External Vibrator (Made in Germany)

Application of Mooser Pneumatic VR Series External Vibrators

A steel formwork carriage was used for creating the inner shell. The concrete is compacted by means of a Mooser compressed air vibrator from the new VR series. The formwork vibrators are attached directly to the receiving plates on the sheathing of the steel formwork carriage and in this way cater for direct transfer of force on to the concrete. Optimal compaction depths of 50  cm and more (depending on the concrete consistency and formwork design) have been revealed thanks to sample borings.

 

The compressed air unit with rapid start-up acceleration swiftly penetrates the characteristic frequency range of each formwork and in this way avoids an excessively large dynamic strain on the formwork carriage. The individual compressed air vibrators are controlled centrally via a corresponding air control unit at each wall side. The vibrators are devised in such a way that these compressed air versions do not freeze up even during the cold  winter.

 

The advantages of these almost maintenance-free compressed air vibrators are also taken advantage of for the cut-and-cover tunnel. The vibrators for the formwork carriage are also stationary and attached directly to the sheathing via the reception plates. The compaction concept foresees that the vibrators only operate at those points where concrete is actually being placed so that the formwork is not unnecessarily affected by the vibration energy. As a result no more than 6 vibrators run simultaneously.

What is external conrete vibrator?

External concrete vibrators attach, via a bracket or clamp system, to the concrete forms. There are a wide variety of external concrete vibrators available and some vibrator manufacturers have bracket or clamp systems designed to fit the major brands of concrete forms. External concrete vibrators are available in hydraulic, pneumatic or electric power.
