The VibroSTA is a vibrating tool system, composed by a vibrator, an isolator and various extension tubes. The vibrator contains an eccentric mass that continuously rotates, generating radial centrifugal force. This lateral/radial force is used to penetrate the soil and then to treat the soil itself, according to the chosen ground improvement technique (vibro compaction or stone columns).
Different length extension tubes allow the VibroSTA to reach any required treatment depth. VibroSTA can be equipped with a Bottom Feed System (BFS), for stone column applications. In this case, a stone tube and a stone tank with a stone gate, will be added to the VibroSTA in order to drive the gravel up to the bottom of the perforation level.
STA offers a wide range of vibroflots for ground improvement jobs. Different models are available depending on the soil conditions and techniques to be implemented. The VibroSTA can be mounted on a crane, on a rig or mast, and on excavator.
