showcased its latest concrete vibration solutions at World of Concrete 2019 in Las Vegas. The leading manufacturer of concrete dowel pin drills, concrete vibrators and vibrator monitoring systems displayed the Stinger concrete electric flex shaft vibrator, M-Box high cycle vibration control solution, and Auto Vibe paving vibrator monitoring systems in Booth C4213.
“At Minnich, we’re dedicated to helping concrete contractors and concrete paving superintendents maximize quality,” says Rob Minnich, vice president of marketing for Minnich Manufacturing. “We’re excited to display our concrete vibration innovations at the show, and will continue to bring products to the industry that support the findings of concrete research facilities across the country.”
Stinger Electric Flex Shaft Concrete Vibrator
The Minnich Stinger electric flex shaft concrete vibrator is a 14.5-pound double-insulated universal motor that can drive the full line of Minnich vibrator shafts and heads from ¾ inch to 2½ inches. Available in a 15-amp (115-volt) version, it offers a more compatible speed range of 11,000 to 13,000 vibrations per minute (vpm) to meet today’s concrete placement challenges.
The unit comes standard with a quick disconnect that adapts to the vibrator shafts and heads of many other manufacturers. A durable protective frame extends vibrator life with urethane end caps that absorb shock while supporting easy-to-grip handles.
The Stinger provides quiet operation meeting Occupational Safety and Health Administration (OSHA) A 29 CFR 1910.95 standards. Its double-insulated motor runs safely when grounded systems are compromised.

Minnich M-Box Vibration Control Solution
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 minimizes time and cost associated with patching structural concrete surface blemishes caused by excessive vibrator speeds.
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 labor and patch material can be expensive.
Minnich M-Box operators can select from speeds of 6,000, 8,000, and 10,800 VPM. The product converts the 230-volt, single-phase outlet of a 3,500-watt generator to 230-volt, three-phase output, allowing the operator to choose a uniform and compatible constant speed under different concrete loads.
Minnich Auto Vibe II and III
The Minnich Auto Vibe vibrator monitoring systems for paving machines can monitor, control and program hydraulic vibrator speeds during the paving process for superior concrete surface results.
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 traveled, 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.
The complete line of Minnich vibration solutions includes high cycle, paving, flex shaft and monitoring units.
Minnich also displayed its dust collection system for on-grade, on-slab, machine- mounted and utility dowel pin drills at the show. The Minnich dust collection system meets the requirements for dowel pin drills found in Table 1 of the OSHA final respirable crystalline silica standard when used with an appropriate filter.
