WIRE ROPE LUBRICATION
Refer to Section 9.
WIRE ROPE INSPECTION AND
REPLACEMENT
General
The inspection and replacement guidelines which follow
comply with United States regulations.
It is impossible to predict when a wire rope will fail; however,
frequent and periodic careful inspection by a qualified
inspector will indicate when the potential for failure exists.
See Wire Rope Lubrication topic in Section 9 of this manual.
Keeping Records
A signed and dated report of the wire rope’s condition at
each periodic inspection must be kept on file at all times. The
report must cover all inspection points listed in this section.
The information in the records can then be used to establish
data which can be used to determine when a wire rope
should be replaced.
It is recommended that the wire rope inspection program
include reports on the examination of wire rope removed
from service. This information can be used to establish a
relationship between visual inspection and the rope’s actual
internal condition at the time of removal from service.
Inspecting Wire Rope
Frequent Inspection
Visually inspect all running ropes in service once each work
shift and observe the rope during operation. Pay particular
attention to areas of the rope where wear and other damage
is likely to occur:
• Pick-Up Points — sections of wire rope that are
repeatedly stressed during each lift, such as those
sections in contact with sheaves.
