A three dimensional wire flying system includes a plurality of winches collectively hanging an object and a control unit for controlling the plurality of winches and the main safety device. Each of the plurality of winches includes a drum unit, a wire wound on the drum unit, a motor unit which provides power to the drum unit, a brake module which stops rotation of the drum unit, a limit switch which operates upon detecting a hardware limit state, and a servo-system. Each of the plurality of winches operates to move the object in a three dimensional space in three directions, including an up-down direction, a left-right direction and a forward-backward direction, and each winch provides a multi-level safety protection.
