Abstract
A tool handling system including an overhead counter-balance and a control bar. The counter-balance uses a series of complementary springs to provide a counter-gravitational force to a suspended tool. When the user wishes to lift the tool from its equilibrium position, the user is assisted by the counter-gravitational force of the springs such that the tool may be lifted with only a small fraction of the force necessary to lift the tool unaided. The control bar will allow users to keep any cable away from a riser or other structure on which the tool is being used.
