A trench shield ladder that hangs on the wall of the trench shield to provide
workmen
safe access to a trench. The ladder is provided with a top platform and hand rails
that extend over the platform. The ladder can be adjusted in length by employing
an extension portion with hooks that hang the extension on the main rungs of the
main ladder. The extension portion is not as wide as the main portion of the ladder
so that the legs of the extension rest between the legs of the main portion of
the ladder. The ladder and extension are provided with stand off arms that hold
the main and extension rungs of the ladder away from the wall of the trench shield.
The present invention is designed to fit on trench shields of varying thicknesses.
