MVE 1300/6N-HC-50A0 OLI MVE-HF 6000rpm 220-240/400-460 0-100Hz Cradle High-Frequency Electric Industrial Motor Vibrator

High frequency electric vibrators are used in construction sites and in precast manufacturing plants to obtain high-quality products (exposed concrete), with excellent aesthetic results and weather resistance. The vibration is transmitted to the concrete indirectly through formworks or mold.

OLI high frequency electric vibrating motors for outdoor use are characterised by high operating efficiency and ease of installation.

Specially designed fasteners (quick-fit terminals) reduce installation and repositioning time.

Used both in prefabrication plants and on construction sites, high frequency electric vibrating motors are the ideal solution for obtaining optimal results in compacting concrete.

When the MVE is switched on a sinusoidal centrifugal force is provided by rotation of the eccentric weights. With only one MVE fitted on a vibrating machine a rotating force is provided resulting in a circular movement of the machine. Two counter-rotating MVE fitted in parallel on the same machine provide a linear force resulting in a linear movement of the machine. The requirement of circular or linear movement depends on the application.

Applications

Vibration applied from outside the concrete is recommended when:

• A high density of reinforcement is required inside the housing.

• The construction elements to be vibrated are high or narrow (dividing walls, columns, beams), therefore difficult or impossible to vibrate with internal vibration systems.

High frequency electric vibrators are used on construction sites and for precast concrete parts where it is necessary to obtain excellent aesthetic results and resistance to atmospheric agents (exposed concrete).

Benefits

• Robust design, built to last

• High operational efficiency

• Easy to install

Features

Thanks to the possibility of being powered at different frequencies, the MVE-HF series OLI vibrators work far from the resonant frequency of the structure to which they are applied; in this way you avoid the risk of damaging the formwork or the mold (as well as the vibrator itself).

Furthermore, the masses of the MVE-HF can be adjusted in order to generate different centrifugal forces, so as to allow the customer to obtain the perfect configuration based on the type of concrete used. The result will be perfect compaction, both from a structural and aesthetic point of view.
