When concrete consolidation is required for remote or mobile applications, there's nothing like a Northrock Backpack Vibrator System. These units are designed for use where electrical power is not conveniently available or for applications where extra mobility is desired. No tangled air hoses or electrical extension cords.

Northrock Backpack Vibrators offer just the right 10,000 vpm mid-frequency and force characteristics required to set material particles in motion quickly for rapid consolidation of homogenous mixes without destroying important freeze-thaw pressure-relief chains produced by small air bubbles. Northrock concrete vibrators are designed to maintain these optimum frequencies regardless of slump, head diameter or other load conditions. 

Northrock Backpack Vibrators are driven by a fuel-efficient two-cycle, 50cc, 2-1/2 hp gas engine. This power unit is lightweight yet powerful enough to drive any of Northrock's 7', 10' or 14' flexible shafts and vibrator heads up to 2" in diameter. A quick connect/disconnect system allows for assembly/dis- assembly in seconds. The power unit is also designed for ease of operation as well as operator comfort. The engine swivels 260° for either right- or left-hand side operation for maximum flexibility and minimum fatigue. The engine throttle control and kill switch are placed conveniently at the side of the operator. An ergonomically designed frame with strategically positioned motor mounts isolate vibration from the operator.
