HOISTING BRACKET FOR CONSTRUCTION MACHINE
To reduce load of attachment work on a truck frame.SOLUTION: A hoisting bracket 20 for a construction machine to be attached on a truck frame 4 of a traveling body is an attachment used in hoisting work of a construction machine provided with: a traveling body; a revolving superstructure arranged on an upper part of the traveling body; and a work machine attached on the revolving superstructure. The hoisting bracket is configured to include a bracket body 21, and a grip 22 rotatably connected to the bracket body 21 via a rotary shaft part. The bracket body 21 comprises: an upper pin hole 21a and a lower pin hole 21b into which connection pins P1, P2 for connecting the bracket body to the truck frame 4 are inserted, respectively; and a hoisting pin hole 21c to which a shackle is attached. The upper surface of the bracket body is formed into a shape to be a slope plane descending from the upper pin hole 21a toward the hoisting pin hole 21c in a state where it is attached on the truck frame 4. The rotary shaft part of the grip 22 is positioned between the centroid of the bracket body and the upper surface.SELECTED DRAWING: Figure 6
【課題】トラックフレームへの装着作業の負担を抑える。【解決手段】走行体、前記走行体の上部に設けた旋回体、及び前記旋回体に取り付けられた作業機を備えた建設機械の吊り作業に用いるアタッチメントであって前記走行体のトラックフレーム４に装着する建設機械用吊ブラケット２０において、ブラケット本体２１と、回転軸部を介して前記ブラケット本体２１に回動可能に連結された把手２２とを含んで構成されており、前記ブラケット本体２１が、前記トラックフレーム４との連結ピンＰ１，Ｐ２を通す上ピン穴２１ａ及び下ピン穴２１ｂと、シャックルを装着する吊ピン穴２１ｃとを有し、前記トラックフレーム４に装着した状態で、上面が前記上ピン穴２１ａから前記吊ピン穴２１ｃに向かって下る斜面となる形状をしており、前記把手２２の回転軸部が、前記ブラケット本体の重心と前記上面との間に位置している。【選択図】図６
