ABSTRACT:
A safety ladder comprises a pair of spaced-apart parallel main support rails which typically extend between the ground and the side of a building. The steps of the ladder are connected between a second set of parallel side rails which are spaced inwardly toward the building, and are interconnected with the main side rails by means of truss-like support braces. This causes the step bearing portion of the ladder to be suspended from the load bearing rails to improve the stability of the ladder. The load bearing rails also act as hand rails, to assist users of the ladder in balancing on the ladder.
