Concrete Vibrators: The Hard Truth

STOW Construction Equipment’s lightweight backpack vibrator allows contractors to conveniently carry the unit around the job site.Packed for portability

STOW Construction Equipment’s lightweight backpack vibrator allows contractors to conveniently carry the unit around the job site.

The flex-shaft BP25H backpack vibrator is ideal for work in medium- to high-slump concrete applications, including small pours, slabs, driveways, stem walls and footings.

It features a 2.5-horsepower Honda gasoline engine and weighs 24 pounds. Its ergonomic design features a swivel shaft connection, quick disconnect knob for easy shaft removal, and built-in oil shut-off. The vibrator is CE compliant and compatible with Multiquip’s entire line of steel and rubber heads, except the 2 3/4-inch long rubber head.

The concrete vibrator is offered with seven steel heads and four rubber heads (which are ideal for epoxy). The heads range in diameter from 7/8 to 2 3/4 inches, with a maximum length of 17 3/4 inches. Flexible shafts are from 2 to 21 feet long.

Multiquip’s backpack vibrator has enough torque to turn rubber heads. The engine features flow-through ventilation to reduce contamination while its cassette-style design minimizes friction and maintains optimum rpm.

Wacker engineers have designed a revolutionary high-cycle, motor-in-head internal vibrator. The IRFUN series is the only motor-in-head vibrator in the industry with an integrated, compact electronic converter in the switch housing.Motorheads take notice

Wacker engineers have designed a revolutionary high-cycle, motor-in-head internal vibrator. The IRFUN series is the only motor-in-head vibrator in the industry with an integrated, compact electronic converter in the switch housing. This means no more separate converters or high-cycle generators to deal with — just plug it into any construction grade, single-phase 115V portable generator.

The micro-converter built into the on/off switch automatically converts the single-phase 60-cycle to a three-phase 180-cycle. This high-tech, solid-state electronic brain even senses “dirty power” (low voltage from a too-small extension cord, erratic voltage from a faulty generator, etc.) and shuts the vibrator down before it can become damaged.

The sealed switch housing encloses electronic components that are embedded in a special resin to ensure protection against moisture, impact and vibration.

Three IRFUN models are available with the converter system. The IRFUN 38 has a 1 1/2-inch diameter head and an effective compaction diameter up to 20 inches. This unit can compact up to 34 cubic yards of concrete an hour. The midsize model, IRFUN 45, has a 1 3/4-inch diameter head and an effective compaction diameter up to 24 inches, which can compact up to 41 cubic yards of concrete an hour. The largest vibrator, IRFUN 57, has a 2 1/4-inch diameter head and an effective compaction diameter of 33 inches to compact up to 57 cubic yards per hour.

The IRFUN motor-in-head internal vibrators are built for reliability and require minimal maintenance. Disassembly and repair are fast because repair parts are designed as component groups. These vibrators feature Class H windings, the most heat resistance available, and motor protection if the vibrator is run outside of the concrete.

Good vibrations

The Multivibe line from JLin Corporation offers a variety of concrete vibrators for decorative concrete, including the Sidewalk Buddy and the Multivibe Cordless Hummer Screed.

Sidewalk Buddy is a vibrator/finisher designed for production edging, grooving, trowel-finishing concrete and vibrating decorative countertops. Round vibrators have problems separating the aggregate in thin slabs for countertops. Using the Sidewalk Buddy’s vibrating trowel for surface vibration eliminates the problem.

The Multivibe Cordless Hummer Screed is a double-duty machine that also serves as a vibrator. It uses the same vibrator as the gas-powered model, but because it is electric, cordless and lighter,The Multivibe Cordless Hummer Screed is a double-duty machine that also serves as a vibrator. It uses the same vibrator as the gas-powered model, but because it is electric, cordless and lighter, it can be used in places other concrete vibrators can’t. The product can be disassembled with no tools and be used as a vibrator, a screed and as a hammer drill.
