The sophisticated Auto Vibe system from Minnich is said to help in optimising concrete pavement surface quality
Minnich Manufacturing is offering new options for the concrete paving market that can boost surface quality.


The Minnich Auto Vibe vibrator monitoring systems for paving machines can monitor, control and program hydraulic vibrator speeds during the paving process for optimising surface quality.

The Auto Vibe II monitors up to 62 hydraulic vibrators during the paving process, recording and displaying real-time data that can be used to ensure proper vibrator operation. Readings are recorded by time, distance travelled, or at the push of a button. Reports can be generated after the data is imported from a USB drive. The system can be installed on any new or existing hydraulic vibrator system.

The Auto Vibe III monitors and records VPM data just like Auto Vibe II, with the added feature of controlling and maintaining the vibrator vibrations per minute (VPM) at the monitor instead of at the manifold. Once the VPM speed is set, the monitor communicates with the manifold and automatically makes adjustments to maintain desired speeds.

Meanwhile, the Minnich M-Box high cycle vibration control solution is an innovative control speed high-cycle power converter that enables high-cycle vibrator operators to control the speed/vibrations per minute (VPM) of up to two vibrators. The M-Box minimises time and cost associated with patching structural concrete surface blemishes caused by excessive vibrator speeds.

The Minnich Stinger is a versatile tool for concrete placement work
In pumped concrete mixes, available/bleed water can be an issue. The faster the vibrator speed, the more water separation occurs and collects on the form faces. Chipping and patching labour and patch material can be expensive.

Minnich M-Box operators can select from speeds of 6,000, 8,000, and 10,800vpm. The product converts the 230V, single-phase outlet of a 3,500W generator to 230V, three-phase output, allowing the operator to choose a uniform and compatible constant speed under different concrete loads.


And the Minnich Stinger electric flex shaft concrete vibrator is a 6.6kg double-insulated universal motor that can drive the full line of Minnich vibrator shafts and heads. Available in a 15A (115V) version, it offers a more compatible speed range of 11,000 to 13,000vpm to meet concrete placement challenges.

The unit is versatile as it comes standard with a quick disconnect that adapts to the vibrator shafts and heads from other manufacturers. A durable protective frame extends vibrator life with urethane end caps that absorb shock while supporting easy-to-grip handles.

The firm says that the Stinger provides quiet operation. Its double-insulated motor is said to run safely when grounded systems are compromised.
