Down-hole torpedo-shaped vibrators for soil compaction are generally termed vibroflots. The vibroflots generate a horizontal mode of vibration. TerraSystems owns both hydraulic and electric vibroflots for soil compaction.
Our electric vibroflots operate at a frequency of 30 Hz and our hydraulic units operate at frequencies of up to 50 Hz. The diameter of the units vary from 12 inches to 16 inches.
