§1616.7. Multiple-Crane/Derrick Lifts - Supplemental Requirements.

(a) Plan development. Before beginning a crane/derrick operation in which more than one crane/derrick will be supporting the load, the operation shall be planned. The planning shall meet the following requirements:

(1) The plan shall be developed by a qualified person.

(2) The plan shall be designed to ensure that the requirements of this Article 15 are met.

(3) Where the qualified person determines that engineering expertise is needed for the planning, the employer shall ensure that it is provided.

(b) When two or more cranes are used to lift one load, a qualified person, other than the operators, shall direct the operation. 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.
