Abstract

The present invention relates to a method, and an apparatus for carrying out the method, in internal or 'poker' vibrators intended for compacting concrete, the vibration-generating movement being imparted to the vibrators by an electric motor housed in the poker and driving an excentric mass, and in which the power, transmission from a power source to the electric motor is effected via an electric cable enclosed in a casing. According to the method, the vibrations generated by the poker vibrator are insulated exclusively to the poker itself with the aid of a vibration-insulating element mounted between the poker and the casing. The method is carried intoeffect in that the poker (1) and the casing (2) are united with a helical spring (4), or alternatively with an element of polymer material, which, in its longitudinal direction, has a central portion (4a) with a spring rate which is higher than the spring rate of the surrounding free portions (4b, 4c).
