Claims

[Scope of utility model registration request]

A crane jib work scaffolding device in which a scaffold board is attached to the back of the crane jib, and a handrail support is attached to the back main pillar of the jib along this scaffold board, and a cylindrical bracket is attached to the lower end of the handrail support. The bracket is fixed perpendicularly to the column, and this bracket is attached to the rear main column of the jib so that the handrail column can be rotated between a use position in which it stands up on the back surface of the jib and a folded position along the side of the jib. A stopper means is rotatably fitted around the main pillar and stops the rotation of the bracket at the use position of the handrail support, and a fixing means for fixing the bracket at the use position. Features: Crane jib work scaffolding device.
