COUNTERWEIGHT DEVICE AND CONSTRUCTION MACHINE
PROBLEM TO BE SOLVED: To provide a counterweight device that reduces the height of transportation, reduces the weight of a body frame and the side closer to a connection structure, and allows a counterweight to be attached to the body frame remotely.SOLUTION: There is provided a counterweight device comprising a support bracket 41 oscillatably supporting a hydraulic cylinder 39 on a base plate 33, a first coupling mechanism that couples a detachable frame 53 and a rear end part 17A of a revolving frame 17 at a position where an upper end of the rear end part 17A is lowered than a cylinder top 39C when a cylinder rod 39A is extended, a second coupling mechanism that couples the support bracket 41 and the rear end part 17A of the revolving frame 17 when the cylinder rod 39A is contracted, a first operation lever 46A that operates the first coupling mechanism, and a second operation lever 62A that operates the second mechanism, the first coupling mechanism being operated with the detachable frame 53 and the hydraulic cylinder 39 working as the center of gravity at the rear side.SELECTED DRAWING: Figure 7D
【課題】輸送高さの低減を図り、機体フレーム及び連結構造体側の重量を軽量化し、遠隔でカウンタウエイトを機体フレームに取り付け可能とする。【解決手段】油圧シリンダ３９をベースプレート３３上で揺動可能に支持する支持ブラケット４１と、シリンダロッド３９Ａの伸長時に着脱フレーム５３と旋回フレーム１７の後端部１７Ａとを、後端部１７Ａの上端がシリンダトップ３９Ｃよりも低くなる位置で結合する第１の結合機構と、収縮時に支持ブラケット４１と旋回フレーム１７の後端部１７Ａとを結合する第２の結合機構と、第１の結合機構を動作させる第１操作レバー４６Ａと、第２の結合機構を動作させる第２操作レバー６２Ａと、を備え、着脱フレーム５３と油圧シリンダ３９を後側重心として第１の結合機構を動作させる。【選択図】図７Ｄ
