Double beam screed vibrator consists of a Beam unit and a Vibrator unit. Double beam screed vibrator is used to vibrate the concrete to give a compact and leveled surface. These vibrators are self-travelling and only require guiding along the formwork, dragged at ends by two operators without working in the concrete.
In internal vibration, the vibrator is immersed in the interior of the concrete and the vibratory waves carry outward to the surfaces. In external vibration, the vibration is applied to the surfaces and the vibratory waves penetrate the interior. On any construction job the vibrators should match reasonably well the concrete mix being vibrated.
