| In 1938, The Exen joint-stock corporation's concrete vibrator made Japanese realize localization, which is worldwidely used for the construction of large dams. In China, this dam vibrator is used for Songhuajiang Dam, Sanxia Dam and other large dams. |

Features of Dam Vibrator:
1. Insert the hydraulic vibrator 3/4/5 into the concrete will gain a more strong vibration. So, for the rigidity concrete, this dam vibrator can press it in short time.
2. Since the number of the vibrator's parts is seldom, it is easy to replace the damaged articles and the maintenance is convenient and easy, too.
3. There are enough vibration-proof devices on the vibrator which is installed on the control arm that can yield freely. For it can freely be operated in the direction of front, back, left and rigjt, up and down, this dam vibrator can work easily with high efficiency.
4. The available radius of the control arm which can rotate 360 ° is 5 meters.Therefore, with its radiusm, it is not necessory to move the main machine.

Vibrator with Large Power for Dam Construction
|
|
Vibrator with Large Power for Dam Construction is a product specially developed for the vibration of concrete used for dam project, flood-proof dyke etc..
The Theory of Design: The switch or the transducer provides 120-125Hz high frequency powder. Through the running of the strong motor, the eccentric weight run to produce powerful centrifugal force.
In addition, in order to escape the top end abrasion when the vibrator contacting the rock, the top end is processed with the abrasion-proof steel.
