LIFTING/LOWERING DEVICE OF WORK MACHINE
PROBLEM TO BE SOLVED: To provide a lifting/lowering device of a work machine which can reduce a burden of an operator caused by work for making the device movable up and down.SOLUTION: A first engagement member is mounted on an upper part of either one of a pair of vertical members through brackets 5 with a bolt, and a second engagement member is mounted on an upper part of the other of the pair of vertical members through the brackets 5 with a bolt. In the first engagement member and the second engagement member, a direction of long holes through which are inserted the bolts, orthogonal to a longitudinal direction of the vertical members, is set to be a longitudinal direction.SELECTED DRAWING: Figure 3
【課題】昇降装置を昇降可能な状態にする作業に伴う作業者の負担を軽減させることができるようにする。【解決手段】一対の縦部材の一方の上部には、ブラケット５を介して第１係合部材がボルトで取り付けられ、一対の縦部材の他方の上部には、ブラケット５を介して第２係合部材がボルトで取り付けられる。第１係合部材および第２係合部材において、ボルトが挿通される長穴は、縦部材の長手方向に直交する方向を長手方向としている。【選択図】図３
