Zusammenfassung: | To improve safety and usability of a step for elevation disposed on a soundproof box of a mobile work machine.SOLUTION: A storage-type locking tool 30 comprises a locking tool main body 40 mounted on a crossbar 23 laid in a recessed groove 13 formed on an external wall of a soundproof box and used as a step and the like, and a stopper mechanism 50 for restricting rotation of the locking tool main body 40 around the cross bar 23 as a center. By changing a mounting state of the locking tool main body 40 of the storage-type locking tool 30 to the crossbar 23 to a storage state in which a load receiving portion 41 of the locking tool main body 40 is disposed in a recessed portion 13 and a developed state in which the load receiving portion 41 is disposed outside of the recessed portion 13, the locking tool main body 40 is used as a platform (step) in elevating the soundproof box in the developed state in use, footsteps can be easily seen in an elevation motion so that stepping-off and the like hardly occurs, and safety elevation can be performed.SELECTED DRAWING: Figure 4
【課題】可搬式作業機の防音箱に設けられた昇降用のステップの安全性と使い勝手を向上させる。【解決手段】防音箱の外壁に設けられた凹溝13内に架設されてステップ等として使用される横桟23に取り付けられる係止具本体40と,横桟23を中心とした前記係止具本体40の回動を規制するストッパ機構50から成る格納式係止具30を設ける。この格納式係止具30の係止具本体40を,該係止具本体40の荷重受け部41が凹部13内に配置された格納状態と,荷重受け部41が凹部13外に配置された展開状態とで,前記横桟23に対する取り付け状態を変更することができるようにすることで,使用時に係止具本体40を展開状態として防音箱を昇降する際の足場(ステップ)として使用することで,昇降動作の際に足元が見やすく,踏み外し等が生じ難くなることで,安全な昇降が可能となる。【選択図】図4 |
