DEAD-END RIGGING/WEDGE SOCKETS
Wedge socket assemblies are popular rigging accessories
and have been successfully used for decades to terminate
wire ropes 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 rope fitted. Failure to do so may
result in the rope pulling through the fitting.
Since state and local laws may vary, alternate attachment
methods may be necessary depending upon work
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 Grove 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 wire rope manufacturer upon
whose wire rope the wedge socket assembly will be used.
Manitowoc/Grove Crane specifies the size, type, class and
line pulls for wire rope, predominately rotation resistant wire
rope, and rigging accessories such as overhaul balls and
h o o k b l o c k s f o r u s e w i t h e a c h n e w c r a n e t h a t i t
manufactures. Other wire ropes and rigging accessories are
available from various vendors. Different wire rope
manufacturers have differing requirements for the
construction, handling, cutting, seizing, installation,
termination, inspection and replacement of the wire ropes
they produce. Their advice should be sought for each
specific type of wire rope 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
rope into the socket before the crane is used operationally.
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 4-4.

Installing Wedge and Socket
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. This will allow the
distortion of the rope strands, caused by the bend
around the wedge, to adjust themselves at the end of the
line.
3.
Make sure the live-loaded side Figure 4-5 of the rope is
directly in line with the ears of the socket and the
direction of pull to which the rope will be subjected. If the
rope is loaded into the socket incorrectly, under a load
the rope will bend as it leaves the socket, and the edge
of the socket will wear into the rope causing damage to
the rope and eventual failure.
4.
Insert the end of a wire rope into the socket, form a loop
in the rope, and route the rope back through the socket
allowing the “dead” end Figure 4-5 to protrude from the
socket. Ensure the dead end of the rope is of sufficient
length to apply end treatment to the dead end after the
wedge has been seated.
5.
Insert the wedge into the loop and pull the live end of the
rope until the wedge and rope are snug inside the
socket. It is recommended that the wedge be seated
CAUTION
If the socket is not positioned with the flat face away from
the boom sections, structural damage will occur.
