WIRE ROPE INSTALLATION -
(ONE PIECE CABLE WEDGE)
The wedge and anchor pocket must be clean and dry.
The end of the wire rope being anchored to the drum
must be clean and dry and not frayed. Anything on the
end of the wire rope to keep it from fraying (i.e. tape or
wire) must not be in contact with the wedge when the
installation is complete. Consult the wire rope manufac-
turer on the proper treatment of the dead end of the wire
rope. Some rope manufacturers recommend when using
rotation resistant wire rope, that the rope end be seized,
welded or brazed before inserting the wire rope into the
wedge socket to prevent core slippage or loss of rope lay.
Take the free end of the wire rope and insert it through
the small opening on the cable drum. Loop the wire rope
and push the free end about 3/4 of the way back through
the pocket. Install the wedge as shown in figure 1, then
pull the slack out of the wire rope. The “dead” end of the
rope needs to extend slightly beyond the end of the
wedge as shown in figure 2.
Using a hammer and brass drift, drive the wedge as deep
into the pocket as possible to ensure it is fully seated and
no further movement is detected.
Check to ensure the wedge does not protrude from either
end of the pocket, causing it to interfere with proper
spooling of wire rope onto the drum (see figures 3 & 4).
If there is interference or the wedge does not seat firmly,
contact the Braden Product Support Department at 918-
251-8511 to determine the proper wedge size.
It is important that the wire rope have the proper tension-
ing when it is installed on the drum. When the wire rope
is first installed, you should operate the hoist, with light to
moderate loads, with reeving that let’s you place these
loads on the block and the drum with all the rope off the
drum except for the last five wraps.
THE CABLE ANCHORS ALONE ON HOISTS ARE
NOT DESIGNED TO HOLD RATED LOADS.
Winch
loads applied directly to the wire rope anchor may
cause the wire rope to pull free and result in the sud-
den loss of load control and cause personal injury,
death, or property damage. A minimum of 5 wraps of
wire rope must be left on the drum barrel to achieve
rated load.
