OLI Concrete Pokers with Electronic Converter – EWO Series

The range of EWO concrete pokers is characterized by a high centrifugal force, constant speed and greater resistance to wear, which makes it suitable even for the most consistent types of concrete and for continuous use. The shaft is supported by four bearings for working in harsh conditions. This makes them suitable for being connected directly to a single-phase power outlet (115 V, 230 V, 50/60 Hz).

The vibrating needle of the EWO is able to reach 12,000 vpm. The electric cable is 10 meters long and the operating tube, flexible and internally reinforced, is 5 meters long. The high centrifugal force is generated by a high frequency electric motor integrated in the vibrating needle.

EWO concrete pokers are equipped with a small polyamide control panel (IP 66 protection), with a switch designed to resist wear and protected by a reinforced seal.

The electronic converter, complete with switch, is integrated in the power cable and housed in a robust aluminium housing, with dust seal, waterproof (IP 66). It is protected against overload, overvoltage, excess temperatures and short circuits. A LED indicates correct operation or the presence of a fault through different colours that correspond to specific errors.
All electronic components are coated with resin to protect them from vibrations, humidity and knocks.
