Needle Vibrator

An increasing number of contractual obligations call for various forms of vibro- compacted concrete for achieving a better and more consistent mixture. The needle vibrator is recommended for vibro- compaction of test cylinders and beams at site and in the laboratory. This instrument can also be used at small construction sites.
A motor fitted on a swivel base drives a flexible shaft, which in turn, vibrates the needle at about 10,000 vibrations per minute. (approx. )
