Wire Rope and reeving
MAINTENANCE
All wire ropes in active service should be inspected daily along with spooling, sheaves,
wedge sockets, and any other wire rope fittings for damage. Once weekly a thorough wire
rope inspection should be made by a competent inspector. A record should be kept of the
inspection on the form provide in the Inspection section.
Refer to ANSI Standard B30.5 for guidelines covering the inspection, maintenance, repair,
and replacement of wire rope. Worn, kinked, birdcaged, fatigued, or otherwise damaged
wire rope must be removed immediately. Wire rope, when properly installed, lubricated,
and employed, will give many hours of satisfactory use. Whereas, a new piece of wire rope
can be immediately ruined if misused. Replace any wire rope found to be in unsatisfactory
condition.
In addition to damage such as kinking, crushing and broken wires, factors such as
corrosion, abrasion, pitting, peening, and scrubbing of outside tires, reduction of rope
diameter, the condition of other components, and proper lubrication are considered. Refer
to section 4 for wire rope lubricating procedures.
Before installing a new or replacement rope, make certain the rope to be used is the proper
type and size. The wrong rope will not function properly and may even be dangerous.

The use of non-rotating 18 x 7 class wire rope is not recommended in multiple
reeving applications and, if used for applications involving single part line, must
not be used with loads exceeding one fifth (1/5) the rated breaking strength. The
inner wires are generally the first to fail on this class of rope making it very
difficult to inspect as broken wires cannot be seen. Refer to ANSI B30.5 for the
necessary inspection procedure and replacement criterion.
If non-rotating or spin resistant rope is used on this crane, the rope must be replaced if two
or more wires are found broken in one lay of the rope.
CABLE REEVING
When reeving the machine for any job, remember that hoisting and lowering speeds
decrease as the number of parts of line increases. For the most efficient use of the
