A. Suitable for flat cement and concrete surface during construction building site and road construction and so on.

B. High speed and efficiency,easy for take.Strickling and vibrating finish together.

C. Operator can adjust the impact force at any moment, manual accelerograph controls vibrating frequency.

D. Concrete surface after vibration,no need to sprinkle dry cement when press polish. It reduce the construction cost and repair frequency greatly.
E. Can avoid situation as concrete surface empty,knob and split completely which usually appear after concrete surface constructing. Finish the firmly,solid and close-graind concrete surface.
