1400A OPERATOR’S MANUAL SET-UP
INSTALLING CABLE ON THE HOIST
NOTE: The cable should preferably be straightened before
installation on the hoist drum.
Install cable on the hoist drum in accordance with the
following procedure.
3. Position the cable over the boom nose sheave and route
to the hoist drum.
4. Position the hoist drum with the cable anchor slot on top.
5. Insert the cable through the slot and position around the
anchor wedge (1) Figure 4-1.
NOTE: The end of the cable should be even with the
bottom of the slot for the anchor wedge.
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.
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 1400A is shipped with a terminator wedge socket which
is National Crane’s preferred type of socket (Figure 4-7).
Other wedge socket types are shown on page 4-10.
To attach a terminator wedge Figure 4-7, use the following
procedure:
1. Match the socket, wedge, and clip to the wire rope and
size the rope with the go and no go hole in the socket.
• The wire rope must pass through the “go” hole and
not pass through the “no go” hole.
• If the wire rope passes through the “no go” hole, the
wedge is the wrong size.
• If the wire rope does not pass through the “go” hole,
the wedge is the wrong size.
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.
CAUTION
If cable is wound from the storage drum, the reel should
be rotated in the same direction as the hoist.
