NCV 10-22 Backpack concrete vibrator - Specialty power tools - Hilti USA (2024)

Helps eliminate the need for a second person to help carry the vibrator – useful when working in tight or crowded spaces, as well as reducing manpower expenses

Helps crews access harder-to-reach areas (such as on a scaffold),or areas where a gas-powered concrete vibrator would not be allowed

Can be more safely used indoors thanks to less exposure to fumes, heat and engine noise

Main on/off switch is easily accessible on the shoulder strap, with a clear indication of battery status – good for planning ahead

The motor-in-head system means there is less vibration on the whip, helping to improve user comfort and reduce fatigue

Choose the right combination for the job

Select the correct concrete vibrator, whip (shaft) length and head diameter for your application. You should be able to fit the vibrator rod down between the reinforcement gaps. For smaller volumes of concrete, a compact pencil vibrator may be more efficient.

Always keep the vibrator vertical

Keep the concrete vibrator head in an upright position for a more even mix of concrete and aggregates. Horizontal movement can lead to uneven compaction and increase the chances of equipment getting snagged on rebar.

Prevent cold joints

These occur when there is insufficient bonding between an older layer of concrete and a new one. To avoid this, push the tip of the concrete vibrator at least 5.9in or into the previous layer of vibrated concrete.

Slow and steady

Be sure to place the vibrator head in the concrete at regular intervals to help avoid uneven compaction. When finished, withdraw the vibrator slowly, no faster than 2.75in per second. If bubbles emerge as the concrete vibrator is withdrawn from the vibrated concrete, more vibration is needed.

Don’t over-vibrate

Stop vibration as soon as the surface of the vibrated concrete develops a lustrous sheen and air bubbles are eliminated.
