In situ concrete consolidation

VH electric high frequency internal vibrators

When constructing industrial floors, walls, columns, slabs, etc., flexible and easy-to-use vibrating systems are required. In such cases high-frequency immersion vibrators are generally used, known as 'poker' or 'spud' or simply 'vibrating needles', which come into direct contact with the concrete, resulting in internal direct vibration.

The VH is a robust and reliable product, which is suitable for compacting the concrete and is appropriate for continuous operation.

  • No overheating
  • Easy maintenance
  • Long life of the vibration head
  • 100% waterproof

CM frequency and voltage converters

The converters of the CM range are designed to supply simultaneously and in a continuous cycle, one or more high-frequency internal vibrators; they are reliable, durable and do not require maintenance. The minimal design and the materials used facilitate the external cleaning, while the special internal air ducting system avoids overheating.

The range offers several models, which are capable of supplying from 1 to 4 immersion vibrators.

  • No overheating
  • No maintenance
  • Optimal cooling
  • Easy cleaning

EWO high frequency internal vibrators with built-in converter

On construction sites, during the consolidation of the concrete, a light, flexible and easy-to-use tool is often required, which can be connected directly to the common, single-phase power lines (230 or 110 Volt, 50/60 Hz). In order to solve this necessity, the EWO range has been developed: high-frequency immersion vibrators equipped with an integrated electronic frequency converter capable of transforming the single-phase input voltage (230V or 110V, 50/60 Hz) into the three-phase voltage (230 V, 200 Hz) necessary to obtain 12,000 vpm.

Compared to the common vibrating needles powered by electromechanical converters, the EWO has several advantages: they are light and flexible; the constant output frequency maintains the maximum centrifugal force and thus a high and consistent performance; and there is protection against short circuits, excessive temperature, voltage and current above or below the nominal values.

  • Reliable
  • Safe & easy to handle
  • No overheating
  • Easy maintenance

Precast concrete consolidation

External electric vibrators

The Oli range of external electric vibrators includes fixed frequency models, 3,000 and 6,000 vpm, and variable frequency models, from 0 to 6,000 vpm.

The Oli external electric vibrators are characterised by high operating efficiency and ease of installation. Specially designed attachment devices (quick-coupling clamps) reduce the time required for installing and repositioning. This vibration system is recommended when high construction elements and narrow walls (partitions, columns, beams) are to be compacted, which are difficult to vibrate with other systems; and the reinforcement density inside the housing is high.

  • Sturdy design, made to last
  • High operating efficiency
  • Easy to install

External pneumatic vibrators

The external pneumatic vibrators have no electrical components. They are powered via an air compressor that spins the rotors inside the vibrator at a very high speed (generally between 10,000 and 17,000 vpm), generating a circular vibration that spreads in all directions. They are used especially in the construction of concrete segments for tunnels, viaducts and bridges.

The pneumatic vibrators offered by Oli have a solid and durable body in ductile cast iron. They are characterised by high reliability and efficiency as well as a compact size. Just like the electric vibrators, they may also be bolted or attached via quick-coupling clamps to formworks or moulds for the purpose of easy movement.

  • Easy handle
  • No electric component
  • No maintenance
