Shoulder-type and high-frequency concrete vibrators compact fresh concrete but differ in mobility and working arrangement.
Shoulder-type vibrator
The motor unit moves with the operator, making this format practical when frequent movement around the jobsite is important.
High-frequency vibrator
High-frequency poker vibrators are available with different head diameters and are suited to planned concrete-placement work where head size and working range are important.
Which one should you choose?
Choose based on mobility, reinforcement spacing, concrete volume, head diameter and expected duty cycle rather than motor power alone.
