Vibrators

For the compaction applied electro-mechanical, electromagnetic and pneumatic vibrators. When pouring concrete monolithic structures with the most convenient is the electromechanical vibrator, consisting of an electric motor, the shaft is eccentrically sit loads - eccentric (or unbalance).

Unions do not allow the shaft to rotate smoothly, causing it to vibrate.

Depending on the principle of vibration transfer concrete vibrators are internal (deep), superficial and external.
