Handheld Concrete Needle Vibrator

Immersion or Needle Vibrators are most commonly used vibrator for concrete. It consists of a steel tube (with one end closed and rounded) having an eccentric vibrating element inside it. This steel tube called poker is connected to an electric motor or a diesel engine through a flexible tubeThe air bubbles are forced out of concrete due to vibrations. The Needle Vibrator, also known as immersion or poker vibrator have a power unit and long flexible tube at the end of which a vibrating head is attached. Wherever compaction is to be done, the vibrating head is inserted in the concrete.Concrete vibrators are used to eliminate air pockets that can remain when pouring concrete that can ruin the integrity of concrete. Without a concrete vibrator, concrete structures can cave in or break apart from weather, earthquakes, and wear and tear over time
