External concrete vibrator​s

External concrete vibrators are used on construction sites and in precast plants to ensure effective external vibration of concrete, producing high-quality exposed concrete elements with uniform surface finishes and excellent resistance to weathering.

In this process, vibration is transmitted indirectly to the concrete through formworks, molds or vibrating tables, ensuring uniform compaction of precast elements.

OLI offers a complete range of external concrete vibrators, including electric and pneumatic solutions, designed to combine power, reliability and operational flexibility.
