G. In standing ropes, more than two broken wires in
one lay in sections beyond end connections or more
than one broken wire at an end connection.
H. Replacement rope shall have a strength rating at
least as great as the original rope furnished or
recommended by the crane manufacturer. Any
deviation from the original size, grade, or construc-
tion shall be specified by a rope manufacturer, or a
qualified person.
61 Rope not in regular use: all rope which has been idle
for a period of a month or more due to shutdown or
storage of a crane on which it is installed, shall be
given and inspection in accordance with above infor-
mation before it is placed in service. This inspection
shall be for all types of deterioration and shall be
performed by a qualified person.
62 Inspection records
A. frequent inspection- no records required
B. periodic inspections- in order to establish data as a
basis for judging the proper time for replacement, a
dated report condition at each periodic inspection
should be kept on file. This report shall cover
points of deterioration listed above.
ROPE MAINTENANCE
63 Rope should be stored to prevent damage or
deterioration.
64 Unreeling or uncoiling of rope shall be done as
recommended by the rope manufacturer and with
care to avoid kinking or inducing twist.
65 Before cutting a rope, seizing shall be placed on each
side of the place where the rope is to be cut to prevent
unlaying of the strands. On pre-formed rope, one
seizing on each side of the cut is required. On
non-preformed ropes of 7/8 in. (22 mm) diameter or
smaller, two seizings on each side of the cut are
required, and for non-preformed rope 1 in. (25 mm)
diameter or larger, three seizings on each side of the
cut are required.
66 During installation care should be exercised to avoid
dragging of the rope in the dirt or around objects
which will scrape, nick crush or induce sharp bends
in it.
67 Rope should be maintained in a well-lubricated
condition. It is important that lubricant applied as a
part of a maintenance program shall be compatible
with the original lubricant and to this end the rope
manufacturer should be consulted. Lubricant applied
shall be the type which does not hinder visual inspec-
tion. Those sections of rope which are located over
sheaves or otherwise hidden during inspection and
maintenance procedures require special attention
when lubricating rope. The object of rope lubrication
is to reduce internal friction and to prevent corrosion.
68 When an operating rope shows greater wear or well
defined localized areas than on the remainder of the
rope, rope life can be extended in cases where a
section at the worn end, and thus shifting the wear to
different areas of the rope.
