1.2
Installing the Wire Rope
Install the wire rope so it is wound correctly as shown or the winch and brake
will not work properly, and could allow the load to escape.
Install the wire rope securely to the winch drum. A poorly secured wire rope
could come loose from its anchor and allow the load to escape.
1.2.1
PURCHASE THE PROPER WIRE ROPE for your application. Keep the
following in mind when selecting a wire rope. Contact a reputable wire rope
supplier for help.
a
BREAKING STRENGTH of new wire rope should be at least 5 times great-
er than the largest load placed on the winch. This is a minimum value and
will vary depending on installation and application conditions.
b
WIRE ROPE LAY must agree with the winding direction of the drum to help
insure proper winding.
c
WE RECOMMEND 7 x 19 galvanized aircraft cable.
1.2.2
INSTALL THE WIRE ROPE using the fl ange clip anchor. See Figure 3.
a
WIND THE END OF THE WIRE ROPE around the drum in the proper
direction as shown, or the winch will not operate correctly.
b
PULL THE END OF THE WIRE ROPE through the hole in the fl ange.
c
INSERT THE CARRIAGE BOLT, loop the wire rope around the bolt, and
install the clip so the wire rope is held by the curves of the clip.
d
INSTALL THE JAM NUT and tighten it until the wire rope is fl attened
against the drum fl ange.
1.2.3
TURN THE HANDLE CLOCKWISE to wind wire rope onto the drum. If
wire rope unwinds from the drum when the handle is rotated clockwise, the
wire rope is installed incorrectly.
Install the wire rope correctly before
continuing.
1.2.4
WIND FOUR FULL WRAPS of wire rope onto the drum by operating the
winch while holding the wire rope taught.
These wraps serve as anchor
wraps. Keep the number of anchor wraps to a minimum. Excessive
anchor wraps may recoil off the drum when the fi re vent is released.
Important!
• Use wire rope and other rigging
equipment rated for the size of the
largest load you will be moving.
• Do not drag the wire rope
through dirt or debris that could
cause damage, or poor operation.
• Always wear protective clothing
when handling wire rope.
