Electrical & Mechanical Pokers
Electric and Mechanical Pokers are essential site equipment for perfect compaction of the concrete by removing air bubbles keeping a uniform mix. Poker vibrators do this by agitating the cement, making it resistant and helps in uniform compaction of concrete products leading to higher structural strengths. While mechanical pokers are cable-driven vibrating shafts ensuring strong performance and economy in tough site conditions where electricity may be lacking, electrical ones run on electric power so you have the comfort of easy use with constant results. Both types are designed for durability and efficiency, making them indispensable for high-quality concrete work in construction projects.
CM – Frequency & voltage converters
CM electromechanical converters are designed to continuously supply internal and external high frequency vibrators operating at 42V 200Hz. Depending on the model, the CMs can feed from one to 4 vibrators simultaneously.
CM type electric frequency and voltage converters have an electric motor coupled to a permanent magnet generator. The system reduces the input voltage, single-phase (230 V, 1 ph) or three-phase (400 V, 3 ph), in low voltage at 42 V and high frequency at 200 Hz to allow the correct operation of the electric vibrators and to guarantee safety operator.
To facilitate greater maneuverability, some models are equipped with a handle or a grip frame with or without wheels.

VH -Electric Poker
The high frequency immersion vibrators of the VH series allow the rapid removal of air bubbles trapped in fresh concrete without any segregation of the elements that make up the mass. The result is a homogeneous final product, durable and mechanically resistant, without cracks or cavities. The wide range available meets all needs in both the private and civil engineering sectors.
The high centrifugal force of the VH pokers is generated by a high frequency electric motor integrated in the vibrating needle. The control switch is protected by a reinforced gasket resistant to continuous use and is inserted in a polyamide housing with IP 66 protection.
The standard VH range has a 10 meter long electric cable and a flexible, internally reinforced control tube, 5 meters long.
For safety reasons, the VH vibrator range operates in very low voltage (42V), for this reason they must be connected to CM series electromechanical or EC series electronic converters.
