ASSEMBLING PRECAUTIONS FOR SLINGING WORK Coordinating Signal System, and Appointing Signal Person Before starting, be sure to coordinate signal system to be used. Appoint one qualified signal person only (if a mul- tiple number of signal persons are used, different signals may confuse the workers, possibly causing an accident). All workers should obey signals only from one signal person. When attaching a wire rope to the lifting parts/components, always use slinging protectors between the wire rope and the lifting parts/components to prevent damage. M324-07-171 Precautions for Lifting • Always use a hook with a latch. • Use only slinging wire ropes and chains that are strong enough.

• Never allow the lifted load to pass over any persons. • Never allow anyone under the lifted load. Rectifying Twisted Wire Rope Rectify the twist or bend of the wire ropes after the work. Store the wire ropes in a specified place. M324-07-173 M324-07-174 6-3
