ABSTRACT:
A portable folding platform apparatus is disclosed which may be removably mounted on an extension ladder having a winch removably mounted at the top of the ladder. The apparatus may be used to lift loads to the top of a house, to the different floors of a building, or onto a roof. The apparatus has a platform with a sliding top which may be used to carry a load. After the apparatus and winch are mounted on the ladder, the winch and cable are then used to pull the apparatus to the top of the ladder. The load may then be moved in a horizontal direction by the sliding top. Two diagonal struts and two vertical struts are used to support the platform. The struts are coupled to two side plates having rollers which allow the apparatus to move up and down the ladder. Guide blocks attached to the side plates assist in guiding the apparatus along the ladder. Two swing arms coupled to the apparatus and the winch have rollers which engage the top surfaces of the ladder. The swing arms rotate as the apparatus moves along the length of the ladder helping to stabilize the apparatus. Quick release connections allow one end of the diagonal struts and one pair of rollers to be uncoupled from the side plates and the apparatus to be quickly removed from the ladder. After the apparatus is removed, it may be folded and easily transported to a job site.
