Multiquip Outboard Motor CV1A ユーザーズマニュアル

Multiquip's CV Series Vibrator Motors are designed to 

work with flex shafts and vibrator heads for consolidation 

of fresh concrete to ensure optimum strength and durability. 

See Table 2 for the required shafts for the different vibrator 

motor models.
These vibrator motors have large vibration-isolated handles  

to protect the motor and the operator. They have a quick-

disconnect knob for easy shaft removal.
The cassette-style motor improves durability and 

performance by minimizing friction and enabling the motor 

to maintain optimum RPM.
The flow-through ventilation feature of these motors 

reduces contamination by taking in air from the rear of 

the motor.

Multiquip's flex-shafts vibrator heads are designed to work 

in medium to high slump concrete. Typical applications 

include small pours, slabs, driveways, stem walls and 

footings.
Typical shaft lengths range from 2 to 21 feet (0.6 to 

6.4 meters). See Table 6 for recommended shaft lengths.
Steel heads, attached to one end of the flex-shaft, generate 

vibration via an eccentric rotator that consolidates the 

concrete by removing air pockets. The round head design 

allows for the transmission of vibration in all directions.
There are 7 different steel head sizes that range from

 inches in diameter. Typical vibration frequency for 

these vibrating heads range from 9,200 to 12,150 VPM 

with 1-inch slump when using electric motors.

Consolidation eliminates pockets of air bubbles maximizing 

strength and eliminating voids. Vibrators consolidate 

concrete by transmitting shock waves which allow the 

aggregate to float freely while pushing lighter trapped air 

up and out of the concrete mix.
A properly consolidated concrete pour will display a thin line 

of mortar appearing along the form near the vibrator and the 

coarse aggregate has been dispersed evenly throughout 

the pour and is not visible.

Vibration time depends on frequency. The higher the 

frequency, the less vibration time is required for the job.

Vibration range (Figure 2) can be defined as "Area of 

Influence". This area of influence (vibrating radius) is the 

distance from the center of the vibrator to the outer most 

edge.

Table 4 shows the vibration radius and spacing for a given 

vibrator head diameter.
