Should we require a vibrator in addition to a static crowd stitcher?
There are certain instances where a vibrator, in addition to a static crowd, is beneficial. However, it has been our experience, as well as others, that a static-vibratory stitcher can not produce a static crowd as high as a static crowd stitcher alone. The primary reason for this is that most static-vibratory stitchers do not use counterweights. If the hydraulic gear drive on a stitcher has the capacity to create 15 tons of pushing force, you need 15 tons of resisting force, which balanced static-vibratory stitchers do not have, hence the driving force is much less than the theoretical maximum.
