Wedge Socket EEC-0053
V1.1
Wedge Socket
Assembly Safety

Use only with standard 6 to 8 strand wire rope of designated size. For intermediate
size rope, use next larger size socket. For example: When using 9/16" diameter wire
rope use a 5/8" size Wedge Socket Assembly. Welding of the tail on standard wire
rope is not recommended. The tail length of the dead end should be a minimum of 6
rope diameters but not less than 6" (See Figure 1).

To use with Rotation Resistant wire rope (special wire rope constructions with 8 or
more outer strands) ensure that the dead end is welded, brazed or seized before
inserting the wire rope into the wedge socket to prevent core slippage or loss of rope
lay. The tail length of the dead end should be a minimum of 20 rope diameters but
not less than 6" (See Figure 1).

Properly match socket, wedge and clip (See Table 1) to wire rope size.

Align live end of rope, with center line of pin.
(See Figure 1)

Secure dead end section of rope. (See Figure 1)

Tighten nuts on clip to recommended torque. (Table 1)

Do not attach dead end to live end or install wedge backwards. (See Figure 2)

Use a hammer to seat Wedge and Rope as deep into socket as possible before
applying first load.
Standard 6 to 8 strand wire rope:
A minimum of 6 rope diameters, but not less than 6"
Rotation Resistant Wire Rope
A minimum of 20 rope diameters, but not less than 6".
