<P>PROBLEM TO BE SOLVED: To provide a vibrator of ϕ 30 mm or less having an impact capacity not inferior to that of ϕ 40 vibrators, and subsidiarily having capability of continuous operating usable in civil engineering sites, durability and workability not inferior to conventional vibrators. <P>SOLUTION: In an externally driven concrete vibrator according to the invention, a vibrating body 1 is configured in such a manner that a vibrating shaft 2 is mounted in a cantilever shape inside an outer cylinder of the vibrating body 1 and planetary motion of the vibrating shaft 2 generates vibration, a rectifier motor 11 being used as a driving motor, a gear 12 being connected to an output shaft thereof in order to reduce rotation to a required one. <P>COPYRIGHT: (C)2012,JPO&INPIT |
