Table Vibrator:

This method is mostly adopted in the laboratories. This is the special case of a formwork vibrator, while the vibrator is clamped to the table. This method is used in making small but precise prefabricated reinforced cement concrete members. In this technique, any member kept on the table gets vibrated.

Platform Vibrator:

It is nothing but a table vibrator larger in size. Sometimes, the platform vibrator is also coupled with jerking or shock giving arrangements so that a thorough compaction is given to the concrete. Platform vibrator is used in the manufacture of large prefabricated concrete elements such as railway sleepers, prefabricated roofing elements, electric poles and etc.
