Description

【０００１】
【発明の属する技術分野】
本発明は法枠等の枠上を移動して荷物の上げ下ろしや、法枠に穴を形成したする作業を行なう場合に使用することができる枠移動作業機械に関する。
【０００２】
【従来の技術】
従来、この種の枠移動作業機械の前後左右の脚部材の先端部には法枠を挟着固定する枠挟着装置が取付けられている。
この枠挟着装置は脚部材の先端部に水平方向に回動可能に取付けられたチャンネル状の固定挟着片と、この固定挟着片の一側面のほぼ中央部の外側面に取付けられた挟着用油圧シリンダーと、この挟着用油圧シリンダーの前記固定挟着片の一側面のほぼ中央部に形成された貫通孔を通過して内部に位置する作動杆の先端部に固定された可動挟着片と、前記固定挟着片を水平方向に回動させる油圧シリンダーを用いた回動装置とで構成されている。

【発明が解決しようとする課題】
従来の枠移動作業機械の枠挟着装置はチャンネル状の固定挟着片を用いているため、挟着できる法枠の寸法が限られるという欠点があるとともに、固定挟着片の一側面の外側面に挟着用油圧シリンダーを取付けるため大きくなり、該挟着用油圧シリンダーが移動のじゃまになりやすいという欠点があった。
【０００５】
本発明は以上のような従来の欠点に鑑み、枠挟着装置を小型コンパクトにできるとともに、法枠の寸法が異なっても確実に挟着することができ、安全に法枠や枠上を移動することができる枠移動作業機械を提供することを目的としている。
【０００６】
本発明の前記ならびにそのほかの目的と新規な特徴は次の説明を添付図面と照らし合わせて読むと、より完全に明らかになるであろう。
ただし、図面はもっぱら解説のためのものであって、本発明の技術的範囲を限定するものではない。

したがって、横枠部材、縦枠部材への挟着片の挟着固定を容易で、楽に行なうことができる。
【００２６】
（４）請求項２は前記（１）〜（３）と同様な効果が得られるとともに、挟着片支持バー回動装置によって、４個の挟着片が枠部材を容易に挟着できる位置に配置することができる。
【００２７】
（５）請求項３、４、６は前記（１）〜（３）と同様な効果が得られるとともに、法枠等の枠以外の所を移動する場合には挟着片が上方へ移動して、支持脚の下端部を地面に支持させることができる。
