A pioneer of industrial vibration technology has introduced a heavy-duty compact electric vibrator that provides high performance on the inside and outside of small diameter precast concrete pipe form cores. The Martin® MB36-3000 Concrete Form Vibrator offers very good compaction of the cast for improved material strength. The rugged design has a high force-to-weight ratio and ensures reliability using high heat-rated internal components, allowing the unit to perform consistently under punishing conditions for extended periods.
