CAB FOR CONSTRUCTION MACHINERY

摘要

PROBLEM TO BE SOLVED: To improve the mounting works and maintenance works of a limit switch by ensuring a mounting space for the limit switch inside the front section of a cab box. SOLUTION: A chamfering section 19A curved in an arcuate shape is formed to the window frame 19 of a front window 18. A projecting section 22A projected in the horizontal direction from the position of the chamfering section 19A and a supporting plate section 22B for a roller 24 are formed to a roller bracket 22 installed to the window frame 19. An opening S is formed between the chamfering section 19A of the window frame 19 and the supporting plate section 22B of the roller bracket 22, and the limit switch 28 is housed in the opening S when the front window 18 is closed. The limit switch 28 is fixed on the internal surface side of a front-side bent section 11A by using a metal fitting 29 near a corner on the upper side of a front section 8B oppositely faced to the projecting section 22A of the roller bracket 22 at the place of window closing in the longitudinal direction.
