Standard 3 dog drive coupling. Hoppt concrete vibrators with flexible shafts are built with an improved pendulum design. This vibrator is designed for the compaction of concrete by immersion of the vibrator head. Compaction improves the strength and finish of concrete by driving out entrapped air. Correct vibration allows the efficient compaction of low slump concrete mixes.

• The vibrator head is driven by a rotating flexible drive shaft that transmits the drive from the drive unit.
• The vibrator head uses an eccentric mass to produce vibration
