SOLUTION: In a hydraulic shovel, a ladder 12 is removably housed in the space 11 defined by an engine mounting portion and a counterweight, via a lower opening 7 of an engine compartment 6. When the ladder is not used, an upper insertion guide mechanism 15 and a lower portion of the ladder are fixed to a wall surface of the space 11 by means of engaging tools 20. On the other hand, when used, the ladder 12 is supported by hooking a hook piece 12c at an upper portion of the ladder 12 on a support member 26.</p> |
