DEAD-END RIGGING/WEDGE SOCKETS

Wedge socket assemblies are popular rigging accessories
and have been successfully used for decades to terminate
cables on mobile cranes. A wedge socket assembly is easily
installed and dismantled but it must be installed and used
correctly. It is essential to use only a wedge and socket of the
correct size for the cable fitted. Failure to do so may result in
the cable pulling through the fitting.
Since state and local laws may vary, alternate attachment
m e t h o d s m a y b e n e c e s s a r y d e p e n d i n g u p o n w o r k
conditions. If alternate methods are selected, the user is
responsible and should proceed in compliance with the
regulations in force. If there are any questions, contact your
local Manitowoc distributor or Manitowoc Crane Care.
Do not mix components from different manufacturers. The
selection, installation and use of a wedge socket assembly
must be in accordance with the requirements of the wedge
socket manufacturer and the cable manufacturer upon
whose cable the wedge socket assembly will be used.
Manitowoc specifies the size, type, class and line pulls for
cable, predominately rotation resistant cable, and rigging
accessories such as overhaul balls and hook blocks for use
with each new crane that it manufactures. Other cables and
rigging accessories are available from various vendors.

requirements for the construction, handling, cutting, seizing,
installation, termination, inspection and replacement of the
cables they produce. Their advice should be sought for each
specific type of cable a crane user intends to install on a
mobile crane.
When assembly is complete, raise the boom to a working
position with a load suspended to firmly seat the wedge and
cable into the socket before the crane is used operationally.
CAUTION!
If the socket is not positioned with the flat face away from
the boom sections, structural damage will occur.
When anchoring the socket to the boom, ensure the flat face
of the socket is in position, as shown, away from the boom
sections (Figure 4-9).

Installing Wedge and Socket

1. Inspect the wedge and socket. Remove any rough
edges and burrs.
2. The end of the cable should be seized using soft, or
annealed wire or strand. If the end of the cable is
welded, the welded end should be cut off. Refer to
Section 1, Wire Rope (Hoist Cable) for wire rope (cable)
procedures. This will allow the distortion of the wire rope
strands, caused by the bend around the wedge, to
adjust themselves at the end of the line.
