To provide a boom vibration damping device capable of suppressing the occurrence of a stick-slip phenomenon during a boom telescopic motion and preventing vibration of a boom.SOLUTION: The boom vibration damping device comprises: a slide member 81 disposed between an outer cylindrical member (e.g., cylindrical member 31B) and an inner cylindrical member (e.g., cylindrical member 31C); and an actuator member 82 provided integrally with or separately from the slide member 81. When the inner cylindrical member (31C) advances to or retreats from the outer cylindrical member (31B), the slide member 81 is minutely vibrated through an operation of the actuator member 82.SELECTED DRAWING: Figure 5
【課題】ブームの伸縮動作時にスティックスリップ現象が発生するのを抑え、ひいてはブームが振動するのを防ぐことができるブームの制振装置を提供する。【解決手段】外側の筒形部材(例えば筒形部材31B)と内側の筒形部材(例えば筒形部材31C)との間に配置されるスライド部材81と、スライド部材81に一体又は別体に設けられるアクチュエータ部材82と、を備えている。そして、外側の筒形部材(31B)に対して内側の筒形部材(31C)が進出又は退入する際にアクチュエータ部材82の作動によってスライド部材81を微振動させる。【選択図】図5
