WORK PART CONNECTION STRUCTURE OF WORK MACHINE
PROBLEM TO BE SOLVED: To reduce the size and the cost of a connection frame by allowing force from a lift cylinder to directly act on a connection bracket.SOLUTION: A first support part (pin hole 53), a second support part (pin hole 52b) and a third support part (engagement pin 107) are respectively formed in a vertical direction intermediate part, an upper end and a lower end of a connection frame 50 disposed on a base end side of an arm 100. The first support part (pin hole 53) is detachably connected to an upper end engagement part (boss part 520) formed on an upper end of a connection bracket 500. The base end of the arm 100 is connected to the second support part (pin hole 52b). The third support part (engagement pin 107) is detachably connected to a lower end engagement part 540 formed on a lower end of the connection bracket 500, and an end of a lift cylinder 105 is connected to the third support part (engagement pin 107).
【課題】リフトシリンダからの力を連結ブラケットに直接的に作用させることで連結フレームの小型低コスト化を図る。【解決手段】アーム１００の基端側に配設された連結フレーム５０の上下方向中間部、上端部及び下端部に、第１支持部（ピン穴５３）、第２支持部（ピン穴５２ｂ）及び第３支持部（係合ピン１０７）をそれぞれ形成する。第１支持部（ピン穴５３）を連結ブラケット５０の上端部に形成された上端係合部（ボス部５２０）に着脱自在に連結する。第２支持部（ピン穴５２ｂ）にアーム１００の基端部を連結する。第３支持部（係合ピン１０７）を連結ブラケット５００の下端部に形成された下端係合部５４０に着脱自在に連結し、かつ、リフトシリンダ１０５の端部を当該第３支持部（係合ピン１０７）に連結する。【選択図】図１
