6. Position the anchor wedge in the drum slot; pull firmly on
the free end (2) of the cable to secure the wedge.
NOTE: If the wedge does not seat securely in the slot,
carefully tap (3) the top of the wedge with a mallet.
7. Slowly rotate the drum, ensuring the first layer of cable is
evenly wound onto the drum.
8. Install the remainder of the cable, as applicable.
Wedge Sockets
To install a wedge socket:
• Make sure the wedge socket is the proper size for the
cable.
• Do not mix components of different wedge socket
manufacturers.
• The wedge socket must meet the requirements of the
wedge socket and wire rope manufacturers.
State and local laws may vary and require different
attachment methods depending upon work conditions. The
user is responsible for alternate attachment methods.
Terminator Wedge Installation
The 600H is shipped with a terminator wedge socket which is
National Crane’s preferred type of socket (Figure 4-6). Other
wedge socket types are shown on page 4-9.
To attach a terminator wedge Figure 4-6, use the following
procedure:
1. Match the socket, wedge, and clip to wire rope size.
• The wire rope must pass through the “go” hole in the
wedge.
• It must not pass through the “no go” hole in the
wedge.
2. Align the live end of rope, with center line of pin.
3. Secure dead end section of rope.
4. Tighten nuts on clip to recommended torque.
5. Do not attach dead end to live end or install wedge
backwards.
6. Use a hammer to seat Wedge and Rope as deep into
socket as possible before applying first load.
Wedge Socket Installation
1. Inspect the wedge and socket. Remove any rough
edges and burrs.
2. The end of the wire rope should be seized using soft, or
annealed wire or strand. If the end of the rope is welded,
the welded end should be cut off. Do not weld on size
6X37 rope. This will allow the distortion of the rope
