EV-403 (al.) L=3.05...5.6
The EV-403 telescopic vibrating rack is designed for compaction and leveling of concrete mix during concreting of roads, floors, platforms and other coatings.
The vibrating rack is a structure consisting of four rectangular aluminum pipes with a length of 3000 mm, mounted with a clamp on which a general-purpose electromechanical vibrator with circular vibrations of the classic IV-99B series or a vibrator of increased service life IV-05-50 is installed. The clamp design allows you to push the rail apart within 2050...3650 mm .
The vibrator mounted on the vibrating rack is a three-phase asynchronous electric motor with a short-circuited rotor with unbalances installed at the ends of the rotor shaft. The unbalances, rotating with the rotor shaft, create a driving force.
To regulate the magnitude of the driving force of the vibrator, the unbalances at both ends of the shaft are double. The adjustment is carried out by changing the angle between the movable and fixed unbalances at both ends of the shaft.
The vibrating rack can work with an adjustable electronic frequency converter, which allows you to change the vibration frequency by increasing or decreasing 1.5 times the nominal (50 Hz), within the permissible value of the driving force, save electricity, limit starting currents, choose the optimal mode of operation.
