A backwardly-located truss pivotally joins the ladders together and includes a hinge at the intermediate portion thereof for pivotal forward movement of the latter from a fully-extended truss position to a folded truss position. The latter movement produces relative lateral movement of the ladders from spaced-apart positions, one toward the other, to near-abutting positions. The frame also includes a hinge to releasably immobilize the hinge and maintain the truss in fully-extended position. The person-supporting plank is removably fixed to and extends between the ladders when the truss in its fully-extended position.
