Having a high frequency immersion concrete vibrator, this needle vibrator is assured of excellent performance. The inner core and terminal tip are composed of a unique steel that has a longer life expectancy. For convenient travel, the vibrator is mounted on a spring-loaded chair that also serves as a drip tray. It contains an oil cooled rotor and an auto air cooled needle for a uniform vibration. Special steel was used for the construction of the end tip as well as the inner core.
