Unlike internal vibrators, external concrete vibrators impart vibrations directly onto formwork. These vibrators are used in the flow, precast, and construction industries. They are also used for the compacting of fresh concrete foundations. They are also used in tunnel linings. They are dependable and easy to maintain.
For the most effective results, it is important to use the correct size of concrete vibrator. This will affect the vibratory energy used and the radius of action. A larger head will affect a larger zone of influence. It is also important to use a high amplitude setting.

When determining the right concrete vibrator for your application, you should consider the number of cycles per minute, as well as the size of the vibrator. In addition, you should also consider the type of vibrator you want to use. For example, a high-cycle external vibrator will be used to compact stiff mixes, such as those used in corners.
A larger concrete vibrator head also has a greater radius of action. The radius of action is the distance the vibrator's tip travels when vibrating. The radius should be four times the tip diameter. In general, the best amplitudes are between one inch and two inches.
It is also important to ensure that the head of the vibrator does not strike a reinforcing bar. This can cause a fracture in the bond between the steel bar and the concrete. It is also important to ensure that the vibrations are evenly distributed. This is done by ensuring that the vibrator supports are correctly positioned and provide a steady vibration.
