  • Page 20 Wire Rope Reel When the wire rope is transferred from a reel to the drum, or from the drum back onto a reel, it must go from “top to top” for overwind winches, or “bottom to bottom” for un- derwind winches, as shown in Figure 3, to avoid putting a reverse bend into the wire rope.
  • Page 21 General Wire Rope Installation Keeper WARNING Ferrule Gloves should be worn when working with or near wire rope to prevent cuts and abrasions. NOTE: The illustrations in this section show a winch with an “overwind” configuration, which is standard. Some winches are configured for “underwind” , with the wire rope spooling onto the bottom of the drum instead of the top.
  • Page 22 Another method is to use the tines of a forklift to bear against the reel flange(s). Again, the friction generated between the tines and the flange(s) will create tension in the wire rope. Finally, the end of the wire rope may be fastened to a fork- lift.
