This person shall analyze the operation and instruct all personnel involved in the proper positioning, rigging of the load, and the movements to be made. A qualified person shall be in direct audible communication with both crane operators at all times to direct the lifting operation. Where two cranes or more are used to lift one load, the rating chart shall be reduced on each crane by not less than 25 percent, unless equalizer or other acceptable provisions assure safe distribution of both vertical and horizontal load to the cranes involved, in which case a lesser reduction may be applied.
