Wire Rope Inspection
Safe operation of your
Load King
Cranes Boom Truck is dependent on the proper use of wire rope in all
operations� The ideal situation is to remove a wire rope from service after receiving maximum service
life, but without sacrificing safety� The end point of useful service life is determined by regular inspections
of the wire rope by competent personnel�
OSHA and other agencies having jurisdiction, issue instructions governing the inspection of wire rope
used on special equipment and in specified industries� All wire rope users are urged to comply with the
law for their particular situation� Inspections must be carried out at stated intervals� When the data
obtained from these inspections indicates that the strength of the wire rope has appreciably decreased,
and that further use would constitute a safety hazard, the rope must be removed from service� It is the
responsibility of the user to know what codes apply to his situation and to comply with their requirements�
In the interest of safety,
Load King
Cranes believes that any wire rope, where failure might endanger
personnel, equipment, or the load, must be removed from service when any of the listed conditions are
detected� We recommend a daily visual inspection of the entire length of rope, and a thorough inspection
at least once per month - including a full written report that is dated, signed, and kept on file� The
following conditions for removal of a wire rope from service should be regarded as a guide, with any
specific regulations covering your equipment and industry taking precedence�
