A safety system for preventing crane operator injury. Two ergonomic tracks are attached on either side of the working crane. A fall transmitter is used whenever a crane operator is not on the floor. The fall transmitter has speed and travel distance governors that limit the speed and travel of certain aspects of the crane. In a further embodiment, a second fall transmitter is utilized by the second crane operator to assure that both operators are aware of and agree to any crane movement prior to commencing such movement.
