Correct Installations
Wedge and wire rope fully seated in pocket
Incorrect Installations
Wedge pulled too
far through anchor
pocket
Wedge not fully
seated
-Wire Rope not tight against wedge
-Wedge may be too large
-”Dead” end of wire rope and/or wedge
may interfere with proper spooling
-Wedge may be too small
THE CABLE ANCHORS ALONE ON HOISTS ARE NOT
INTENDED TO HOLD RATED LOADS.
Hoist loads applied directly to the wire rope anchor may cause
the wire rope to pull free and result in the sudden loss of load
control and cause property damage, personal injury or death. A
minimum of 5 wraps of wire rope must be left on the drum barrel
to achieve rated load.
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 manufacturer 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.
WIRE ROPE INSTALLATION
(ONE PIECE CABLE WEDGE)
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 gure 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 gure 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. Applying a load on the
wire rope will also help seat the wedge in the pocket.
Check to ensure the wedge does not protrude from either
end of the pocket, causing it to interfere with proper spool-
ing of wire rope onto the drum (see gures 3 & 4).
If there is interference or the wedge does not seat rmly,
contact the BRADEN Product Support Department at
1-918-251-8511 to determine the proper wedge size.
It is important that the wire rope have the proper tensioning
when it is installed on the drum. When the wire rope is rst
installed, you should operate the hoist, with light to moder-
ate 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 ve wraps.
