Abstract

A needle vibrator for vibrating concrete in formwork, the advantage of which is an unusual structural simplicity with high performance, comprises a rotor in a single piece rotating on a first end bearing, on an intermediate bearing and on a second end bearing, a section of the rotor between the first end bearing and the intermediate bearing constituting a shaft of an electric motor and a section of rotor between the intermediate bearings and the second end bearing constituting an eccentric mass. <IMAGE>
