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 through wire rope inspec-
tion should be made by a competent inspector. A
record should be kept of the inspections on 4-5.
Refer to Wire Rope Users Manual, section 9 and ANSI
Standard B30.5 for guidelines covering the inspection,
maintenance, repair, and replacement of wire rope.
Worn, kinked, birdcaged, fatigued or otherwise dam-
aged 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.
MAINTENANCE AND LUBRICATION
WIRE ROPE AND REEVING
Replace or repair any items found to be in unsatisfacto-
ry condition.
In addition to damage such as kinking, crushing and
broken wires, factors such as corrosion, abrasion, pit-
ting, peening and scrubbing of the outside wires, reduc-
tion of rope diameter, the condition of other components
and proper lubrication are considered. Refer to page 4-
26 for wire rope lubricating procedures.
Before installing a new or replacement rope, make cer-
tain the rope to be used is the proper type and size. The
wrong rope will not function properly and may even be
dangerous.
