PROBLEM TO BE SOLVED: To provide a removal type lifting step of a construction machinery comprising a structure capable of preventing a step from jumping and being released.SOLUTION: A lifting step 1 comprises: a step body 6; and a bracket 7 fixed to a side face of a crawler frame 3 and to which the step body 6 is hooked. The step body 6 comprises: an insertion part 14 which is inserted into a space between a top plate 9 of the bracket 7, and a pin 10 disposed on the bracket 7; and a recessed state hook part 15 extending from the insertion part 14, and hooking to the pin 10 from an upper side. The insertion part 14 is inserted into the space between the top plate 9 and the pin 10, the hook part 15 is brought into contact with the pin 10, then, a tip part side of the step body 6 is rotated downward, around the pin 10, thereby the top face of the insertion part 14 contacts a rear face 9a of the top plate 9, and the step body 6 is hooked to the bracket 7.SELECTED DRAWING: Figure 3

    【課題】ステップが跳ねて外れることを防止できる構造を備えた建設機械の取り外し式の昇降用ステップを提供すること。【解決手段】昇降用ステップ1は、ステップ本体6と、クローラフレーム3の側面に固定され、ステップ本体6が掛止されるブラケット7とを備える。ステップ本体は6、ブラケット7の天板9とブラケット7に設けられたピン10との間に差し込まれる差込部14と、差込部14から延在され、ピン10に対して上方から掛合する凹形状の掛合部15とを有する。天板9とピン10との間に差込部を14差し込んで掛合部15をピン10に当て、その後、ステップ本体6の先端側をピン10まわりに下方へ回動させることで、差込部14の上面が天板9の裏面9aに当接してステップ本体6がブラケット7に掛止される。【選択図】図3
