عربىVibrating concrete helps eliminate air pockets that can remain when pouring concrete, ensuring it penetrates tight crevices and prevents the unmistakable honeycomb effect. This is an important concrete compaction technique that construction professionals use to ensure the strength and integrity of their finished concrete projects.
There are two main types of vibrators, the gas and the electric, but both work effectively to remove air bubbles. A gas vibrator is portable with no electric cords or air hoses to get tangled up on a job site, making it ideal for remote concrete construction jobs where electricity is not available.
The petrol engine concrete vibrator is a popular alternative for those who do not have access to electrical power. These units connect to standard flex drives (shafts) and vibrating heads that are used in concrete construction.
Features of a petrol engine concrete vibrator
Petrol Vibrators are powered by a four-stroke gas engine which offers extra portability where electric current is not readily available. These engines are also easier to operate than electric motors, and have higher RPMs resulting in more complete removal of air pockets from the concrete.
Backpack mounted gasoline vibrators swivel full 180deg for more maneuverability when navigating difficult concrete construction job sites. This feature also prevents the flexible drive from twisting excessively as the operator changes positions and allows the vibrating head to be pulled out more easily, reducing the need for frequent stops while on the job.
VMG gasoline vibrators feature a centrifugal clutch which disengages the flex-drive and stops rotation of the vibrating head when the head is removed from the concrete. This feature also reduces the risk of damage to the flex-drive and high-speed bearings.
