Abstract: A pedestal scaffold having a base member with an upwardly extending mast and a work cage mounted thereon for vertical movement. Retractable outriggers with ground-engageable pads are extendable outwardly on the cage side of the scaffold and lockable into support position to provide a large support area for the elevated work cage. Ground-engageable casters are mounted on the base and the cage and the cage is releaseably locked to the base. When the base and cage are locked together, the scaffold can be moved horizontally on the base and cage casters with the mast being vertical. When the cage is unlocked for vertical movements, scaffold weight is transferred from the cage casters to the non-rolling outrigger pads so that the scaffold cannot be moved along the ground when the cage is elevated. If the cage-side outriggers are not properly braced, the cage can be unlocked from the base but cannot be raised off the ground.

Abstract: A walking stepladder has a pair of substantially identical ladder sides, relatively hinged at the top, each side having step rungs for ascent or descent of the ladder from either side. In walking the ladder, the user straddles the ladder top with his legs supported by opposed rungs at each side of the ladder, and shifts his body weight from side to side while concurrently retracting and extending the ladder sides to effect stepwise ladder movement to one side or the other. Releasable means is provided for limiting inward or retracting movement of the relatively hinged ladder sides to prevent ladder instability or collapsing while being walked.

Abstract: A pedestal scaffold having casters on the scaffold base to permit the scaffold to be rolled horizontally while the scaffold is in a generally vertical position. Retractable outriggers are extended outwardly and locked in position to provide a large support area for the scaffold, with the act of extension and locking of the outriggers causing the casters to lift off the ground so that the scaffold cannot be moved when in use. When the outriggers are not in use and the scaffold is movable on its casters, the casters support the scaffold with a substantial tilt from elevation so that it cannot be used. Additional wheel support frames are provided so that the scaffold can be tilted down for rolling transport, such wheel support frames also serving to protect the user in case the scaffold should tip over when it is generally vertical and supported on its base casters.
