Electric external vibrators suitable for large and small projects on building sites or in concrete factories.

Our program distinguishes various types of ETR electric external vibrators with feet mounting and ETRS electric external vibrators with rapid coupling connection.  For ETR as well as ETRS, we offer a total package of electronic frequency variators for adjusting the speed somewhere between  0 – 3.600 rotations per minutes. On request we also offer complete switchboxes, with thermical overload relais and control lights, for connecting several vibrators.

    • Rotors are produced with low loss lamination core for increasing efficiency and reducing temperatures.
    • Winding insulation is developed according to the ASTM-method with class H polyester resin.
    • Ductil cast iron housing and high resistance aluminium housing for reducing body stress.
    • NiCrMo heat-treated steel shafts.
    • High load capacity bearings, lubricated with special “long-life” grease.
    • Labyrinth type bearing seal with wide restraining chamber.
    • Excentric weights with easy and precise adjustment.
