Abstract

This invention relates to a method and equipment for fire fighting and rescue in conjunction with high rise buildings. A balloon having a capacity for lifting objects is coupled with a gondola for transporting people and equipment to and from an elevated location. The balloon is movable vertically relative to the gondola so that the balloon may be positioned out of the way once the gondola reaches a desired working height. Also, the balloon is compartmentalized so that, if one or more compartments become deflated, the remaining compartments will have sufficient lifting capacity to hold the gondola and its cargo. Elevator means on the gondola is provided for raising and lowering people and equipment to and from the ground so that the gondola and balloon need not be raised and lowered on a continual basis. A water gun and harpoon gun disposed on the gondola along with other necessary fire fighting equipment provide for complete fire fighting and rescue from the elevated location.
