【従来の技術】
従来、法枠上を移動しながら作業を行なう法枠移動作業機械は、該法枠移動作業機械の走行装置の作動と、ウインチの作動によって上下方向に移動するように構成されている。
【０００３】
【発明が解決しようとする課題】
従来の法枠移動作業機械は比較的傾斜のゆるい法枠上の上下方向の移動はスムーズに行なうことができるが、傾斜のきつい法枠上では法枠移動作業機械が転倒方向に荷重が加わり、スムーズに上下方向に移動しづらいという欠点があった。
【０００４】
本発明は以上のような従来の欠点に鑑み、傾斜のゆるい法枠上は勿論のこと、傾斜のきつい法枠上でもスムーズで、安全に上下方向に移動することができる法枠移動作業機械を提供することを目的としている。
