An erectable and transportable scaffold cage adapted to be engaged on and supported on a support beam comprises front and rear frame structures which are pivotally interconnected by means of parallel side braces which are connected between the frame structures. A reinforcing frame is pivotally connected to the lower ends of each of the front and rear frames and the front frame is pivotal outwardly from the rear structure to form a cage within the front and rear structures and the side braces having a floor formed by a scaffold plate which is supported on the reinforcing frame. The plate has upright bottom edges which fit flush against the insides of an angle member forming the sides of the front frame structure so that it facilitates the holding of the structure in an erected cage forming position. A flexible member such as a chain is connected between the upper ends of each side of the front structure to the upper ends of each side of the rear structure. The rear structure also carries a bolt having a pawl which is slidable therealong and which may be engaged against a support structure such as an I-beam by threading a wing nut onto the bolt behind the pawl to lock it in position.
