The invention comprises a balloon system for lifting loads. A balloon (100) is attached to the apex (205) of a series of guy wires (201, 202, 203). The guy wires are attached to moveable or stationary anchor points, such as the ground or heavy vehicles. A pulley (300) is suspended from the peak or apex of the guy wires. A winch line (204) is routed from a lift winch on the ground over the pulley to a hook. The load is attached to the hook for lifting. The balloon comprises an airdam (101). The airdam provides lift and control in windy conditions. The position of the balloon can be controlled by moving the locations of the guy lines (201, 202, 203) independently or in unison, or by changing the length of each or all of the guy lines independently or in unison. The system also provides a platform for lifting various loads to a position above the ground. |
