<p>PROBLEM TO BE SOLVED: To provide a simple automatic lifting prefabricated scaffolding for performing work safely especially at a narrow and dangerous high place where a tower lift and a boom lift cannot be carried in or at a secondary scaffolding, in construction of inspection, repair and painting of a lower layer part of a large-scale bridge having a complex shape such as Kansai International Airport Connection Bridge.SOLUTION: In an automatically expandable actuator scaffolding, an automatically expandable actuator is installed and fixed on a floor rear surface of a simple prefabricated scaffolding which is light and small-spaced, and the automatically expandable actuator can be expanded/contracted freely by an operation of an external controller, so that the simple prefabricated scaffolding can be elevated with an operator to arbitrarily build a work scaffolding at a high place.</p> |
