5-4. Wire Rope Replacement
For hoists reeved Two Part Single, see paragraph 5-4a. For
hoists reeved Two Part Double see paragraph 5-4b.
a. Hoists Reeved Two Part Single:
Refer to Figure 5-3 for parts identification and proper rope
reeving.
1) Push "DOWN" button and run old rope out until stopped
by lower limit switch.
2) Dissemble the load block by removing the screws (9,
Figure 8-9A) and one spring pin (3, Figure 8-9A). Clean
and inspect the block, hook, sheave, bearings, and pin
for wear, damage, etc. Replace parts as necessary. Do
not reassemble the load block at this point.
3) DISCONNECT POWER from the hoist and remove the
short end cover.
4) With a screwdriver, push the spring guide plate (1, Figure
5-1) out of the slots in the limit switch nuts. Turn the zinc
slotted nut (3) back to about the center of the threaded
screw. DO NOT DISCONNECT THE WIRES FROM THE
LIMIT SWITCHES.
5) With the end cover off, connect hoist to power supply. Be
sure the green wire is grounded.
6) Carefully jog the "DOWN" button until all the old rope is
run off and the drum socket opening is accessible.
7) DISCONNECT POWER from the hoist.
8) Disconnect old rope dead end eye by removing one dead
end anchor screw (A, Figure 5-3) and loosening the other
screw (B) approximately three turns. Lift the dead end
eye up and slide the anchor pin back by grasping the
head of screw (B).
9) Slide the sleeve fitting out of the drum socket. Remove
and discard the old rope.
10) Place paper on floor to protect the new wire rope from
dirt and grit. Stretch the new rope out on the paper with
the sleeve fitting end toward the hoist. Relieve any twist
in the new rope.
11) Insert the new rope's sleeve fitting into the drum socket,
making sure the fitting is properly seated.
12) Push the "UP" button until about half of the new rope is
wound onto the drum. Apply slight tension to the rope
with a gloved hand to wind rope evenly on the drum.
13) Attach the dead end by placing the new rope's eye
fitting over the anchor pin, while making sure there are
no twists in the rope. Be sure to replace and tighten
both anchor pin screws.
14) Reassemble the load block onto the new wire rope. See
Figure 8-9A for aid in reassembly. Refer to Figure 5-3 to
make sure that the rope is reeved correctly.
15) Adjust the limit switches per paragraph 5-2.
16) Lubricate the wire rope per paragraph 5-5a. Test the
hoist and break-in the wire rope per paragraph 2-6b.
