Patent attributes
A hoisting system for high-rise buildings which incorporates upright rails mounted on outer walls of the building, a lifting block for each rail. A truss section attached to two lifting blocks to form a loading platform for people or hardware. Doors and windows provide access from the building to the platform, which may be enclosed. The rails are secured on metallic trusses mounted in upright position inside the building structure. The metallic truss can have stairs or elevators for transporting people. The platform can be divided into compartments for holding trays. Guide rollers on the sides of the trays and drive wheels under the trays move the trays into and between the compartments. In this manner cars may be parked in limited space by being lifted to a floor and moved to an open compartment. The platform can be used for emergency evacuation, for construction, parking, or fire fighting.
