Abstract
A vertically placed ladder is positioned approximately 3 to 5 feet from a building and has attached thereto a horizontal beam which is also attached to a vertical stand placed on the roof of the one-story building. The horizontal beam has a U-shaped interior channel within which there is located a roller assembly designed to roll along tracks within the interior of the U-shaped channel, either flat or semi-circular, along the length of the horizontal beam and has attached thereto a winch line which is connectable to a load to be lifted from the earth's surface in a vertical line. The roller assembly also allows the load to be moved along a straight horizontal line until the load is above the surface upon which the load is to be deposited, and then the winch line allows the load to be lowered to the surface upon which the load is to be deposited.
