the crane unsafe, the operator must secure the crane and notify  the  crane  crew  supervisor. The  Operator’s  Daily  PM  Report,  NAVFAC  Form 11260/4, is also used with the ODCL when performing the crane prestart inspection. The ODCL is turned in to the crane crew supervisor at the end of each day or shift for reviewing and signing. The NAVFAC Form 11260/4 is turned in to dispatch. As outlined in the NAVFAC P-307, the minimum requirement for retaining ODCLs is those completed during the current month and during the  previous  month  of  operation. Wire Rope Inspection Part  of  the  ODCL  inspection  is  the  thorough inspection of all wire rope before using a crane. All running rope in continuous service must be visually inspected  for  crushing,  kinking,  corrosion  or  other damage,  broken  wires,  and  proper  lubrication  (fig. 12-36). Other areas to inspect are wire rope sockets, swage fittings, swivels, pendants, and securing hardware for wear. Hoist drum end fittings need only be disconnected or disassembled when experience or visible indications deem it necessary. The exact time for replacement of wire rope cannot be given because many variables are involved; however, safety  depends  upon  the  use  of  good  judgment  in evaluating  wire  rope. The following conditions are reasons for wire rope replacement: 1.  Running  ropes.  six  or  more  broken  wires randomly distributed, broken or torn wires in one lay, or three broken wires in one strand in one lay. Replace end Figure  12-36.—Common  wire  rope  defects. 12-23
