Conventionally, each protector is of sheet metal and the slots are usually at about thirty degrees and have a selected retaining means adapted to engage a rung of a ladder to retain the protector on the ladder stile. In one embodiment a pin or rod is disposed to engage a rung. In yet another embodiment a pivoted hook is disposed to engage a rung of a ladder and in yet a third embodiment a pivoted tab having a sloped engaging edge is adapted to be swung into a retaining condition and position.

Abstract: A ladder hoist attachment consists of a boom and prop combination that allows a conventional ladder to be used to hoist heavy loads. The boom assembly consists of a number of feet that removably attach to a rung of the ladder; a boom that extends horizontally over the top rung of the ladder; and braces connecting the feet and boom that also rest against the top rung of the ladder. One end of the prop removably attaches to a lower rung of the ladder. The other end of the prop has a vertical step to hold the ladder at a predetermined distance away from the edge of the roof. A winch or pulley is suspended from the end of the boom extending over the top rung of the ladder to allow loads to be lifted through the prop and between the ladder and the building. After the load has been lifted above the height of the roof, the end of the prop against the building is lifted by the user to allow the ladder to be moved to rest against the edge of the roof, thus allowing the load to be lowered on to the roof.
