ABSTRACT:
A ladder scaffold is suspended from rods inserted through the hollow rungs of a ladder. The ladder scaffold includes at least two ladders, at least two platform braces, and a platform. Each platform brace has three rods, two long members, and two short members. Two of the rods are inserted through the hollow rungs of a ladder. The long members are attached to the ends of one of the rods and extend downwards from the ladder. The short members are attached to the ends of the second rod. The short members extend horizontally from the ladder towards the surface against which the ladders are leaning. The third rod serves as a pivot point between the long members and the short members. The platform is supported by the short members and extends between the ladders. The long and short members can be attached to the rods at various points, so that the platform can be leveled. The ladder scaffold folds for easy transport. The ladder scaffold may or may not include a safety bar.
