MOVABLE WORKING BASE MADE BY BRIDGE-BUILDING SCAFFOLD BETWEEN A PAIR OF LADDER-SHAPE SUPPORTS

摘要

PURPOSE: A movable working base is provided to prevent an operator from falling to the ground by missing operator's footing on a scaffold without a folding unit and to restrict the operator from tripping on the scaffold. CONSTITUTION: A movable working base made by bridging a scaffold(3) between a pair of ladder-shaped supports has band-type projection units(8) arranged near both ends of the scaffold along the longitudinal direction to have the width detected by the sole of the operator's foot. Linear projection units(9) are disposed near both ends of the scaffold along the transverse direction and detected by the sole of the operator's foot. The band-type projection units are integrated with the scaffold. The section of the band-type projection unit is formed in a support shape. The linear projection unit is formed as an upward-bent unit made by bending or extrusion-molding the end of a cover(10) of the scaffold mounted at the transverse end of the scaffold.
