To provide a connecting device for a work machine capable of easily inserting connecting pins, which connect a plurality of components of the work machine with each other and are placed inside the components, into holes from the outside of the components, the connecting pins, a connecting pin attachment device and a method of releasing the connecting pins.SOLUTION: A crane 10 comprises a boom 16, a jib 18, connecting pins 70, and a pin releasing tool 80. The boom 16 and the jib 18 are connected by the insertion of the connecting pins 70 into boom-side hole parts 16Q of the boom 16 and jib-side first hole parts 18Q and jib-side second hole parts 18S of the jib 18. An operator inserts the pin releasing tool 80 from the jib-side first hole part 18Q and engages it to the connecting pins 70. Thereafter, when the operator pulls out the pin releasing tool 80, the connecting pins 70 are inserted sequentially into each hole part while being pulled out.SELECTED DRAWING: Figure 3

    【課題】作業機械の複数の構成部材同士を連結する連結ピンであって前記構成部材の内側に配置される連結ピンを前記構成部材の外側から孔部に容易に挿入することが可能な作業機械の連結装置、連結ピン、連結ピン装着器具および連結ピンの脱離方法を提供する。【解決手段】クレーン10は、ブーム16と、ジブ18と、連結ピン70と、ピン脱着ツール80と、を備える。ブーム16のブーム側孔部16Qとジブ18のジブ側第1孔部18Qおよびジブ側第2孔部18Sとに連結ピン70が挿入されることで、ブーム16とジブ18とが連結される。作業者は、ジブ側第1孔部18Q側からピン脱着ツール80を挿入し、連結ピン70に係合させる。その後、作業者がピン脱着ツール80を引くと、連結ピン70が引っ張られながら各孔部に順に挿入される。【選択図】図3
