To provide a mobile work scaffold device which does not interfere with lifting even while it is configured to be able to move to a site in a narrow state, expand and move an expansion scaffold from a fixed scaffold after movement to the site, raise a work scaffold to a place higher than a high installed article which has passed through an inner opposite gap of the fixed scaffold, and support the expansion scaffold by a long support crosspiece.SOLUTION: This mobile work scaffold device is configured such that the inside part of a support crosspiece 7 of an expansion scaffold 4 is disposed in an inner opposite gap 6 of a fixed scaffold 3 in a narrow state during movement, but during lifting, the expansion scaffold 4 is expanded to retreat from the gap 6 and to be positioned below the fixed scaffold 3, thus functioning as a falling prevention reinforcement material.SELECTED DRAWING: Figure 3
【課題】幅狭な状態で現場まで移動でき、現場まで移動させたら拡張足場を固定足場から拡張移動させるととともに、固定足場の内側対向間隔内を高所架設物が相対通過してこれよりも高所まで作業用足場を上昇させることができ、しかもこの拡張足場を長い支持桟で支持できる構成でありながら昇降時の妨げにはならない移動式作業用足場装置を提供すること。【解決手段】移動時の幅狭な状態では、拡張足場4の支持桟7の内側部は、固定足場3の内側対向間隔6に配設されるが、昇降時には拡張足場4が拡張されることでこの間隔6内から退避して固定足場3の下部に位置し倒れ防止補強材として機能する構成とした移動式作業用足場装置。【選択図】図3
