High-Frequency Quickly-fix External Vibrator is mainly used in the manufacture of the large concrete prefabricated components, such as the construction of the road, rail way, bridge, culvert concrete, especially the construction of T simply supported beam, I-beam and box-beam.

It has the functions of preventing input phase short, input under-voltage, DC overvoltage, over current, over load and overheat by using electronic frequency conversion. It can markedly reduce the damage of the formwork with the high frequency and low amplitude vibration. The small size, light weight, convenient assemble and disassemble make it especially usable on the large formwork.
