Abstract
PURPOSE:To make easier the maintenance and inspection of the feet of a marine platform by using a system in which the scaffold device is loosely attached to the feet with rack of the marine platform and an elevating driver consisting of a pinion and a brake is provided to the scaffold. CONSTITUTION:An elevating driver 6 is actuated, a pinion 7 is geared with a rack 3, and a scaffold device 5 is vertically moved along feet 4. Since a beam 13 is provided with a large number of bolt-piercing holes and the distance between the adjacent split pieces can thus be optionally selected, the length of each side of the scaffold device of a triangle form can be extended or shrunk and can therefore be attached to the feet 4 of different sizes.
