Abstract

A sawing-vibration inhibitory device for an upper rotatory construction machine, which is applied on an upper rotatory construction machine which comprises an upper rotatory body 2 horizontally rotatable around a rotation axis S on the lower movable body 3 and an operation machine installed for forming moments on the upper rotatory body 2, which is characterized in that: the upper rotatory body 2 is installed with a pegtop stabilizer 10 which comprises a rotation body 11 having a large inertial moment and rotating at high speed around a pegtop axis J by a driving motor 12 and a support element 13 movably supporting the rotation body 11 on the surrounding of an advancing axis P orthogonal to the pegtop axis J of the rotation body 11; and either pegtop axis J or the advancing axis P being parallel to the rotation axis S, with the other being disposed parallel to the moment axis of the operation machine of the upper rotatory body 2.
