Wedge

Gunnebo Johnson open wedge sockets combine positive attachment with optimum versatility. Easy-to-change Gunnebo Johnson wedge sockets consist of a C-1040 normalized and tempered cast steel body, a C-1040 coldfinished bar stock pin with cotters, and a ductile iron wedge to specific wire rope size. Together, wedge and body act as a vise which grips the wire rope and locks it in place.

Gunnebo Johnson wedge sockets may be used with multiple sizes of wire rope. To switch from an overhaul ball application calling for a 7/8-inch wire rope to a block application calling for a 1-inch rope, it is not necessary to buy a complete wedge socket. A simple change-out of wedges will suffice. Of the 18 models of wedge sockets offered by Gunnebo Johnson, all can be adapted to at least two sizes of wire rope. The WS-4 and WS-5, in fact, will adapt to three sizes.

Be sure that the wedge is correct for the wire rope size. Each socket manufactured by Gunnebo Johnson has a model number and acceptable rope sizes cast into its body. Each wedge has the rope size and particular socket model it will fit. Wedges are also coded by means of color. Red indicates that the wedge is for the largest size of wire rope stated on its socket. Green indicates that the wedge is for the smallest size of rope stated on its socket. Blue indicates that the wedge is a rope size of 9/16 inches; black for 7/16 inches.

When using wedge sockets note that two precautions should be taken.

1. Make sure that a sudden jolt or impact does not dislodge a wedge. When installing wire rope, always pre-load the wedge with wire rope in place. Check frequently to re-tighten or re-position as necessary.

2. Make allowance for the crimping effect common with all types of wedge sockets. Experience shows that it will reduce the Safe Working Limit of a line by 20 percent.

Strength of wire rope is less than the strength of the wedge socket. WLL of the wire rope is sole responsibility of the customer and/or user.

Do not exceed working loads stated by wire rope manufacturer.

Make allowance for the wedge socket grip efficiency. The grip efficiency can reduce wire rope breaking strength by up to 20%. After installation of the wire rope and wedge, seat the wedge by anchoring the wedge socket and applying the maximum allowable line pull to the wire rope live end.

A sudden jolt or impact may unseat the wedge. Therefore, the dead or short end of the wire rope shall be clipped with a U-bolt or otherwise made secure.

Wire rope clips used in conjunction with wedge sockets shall be attached only to the unloaded dead end of the wire rope. When a wire rope clip or other device is attached to the dead end of the wire rope, the spacing between the wedge socket and other device shall be in accordance with Gunnebo Johnson Corporation requirements. Where it is desirable to restrain the dead end of the wire rope, it is allowable to have a loop, keeper, or other device around the live end of the wire rope provided it neither restrains nor constrains the live end. Check frequently to re-tighten or re-position wire rope clips as necessary.

Each wedge socket body adapts to two or more wire rope sizes by using a specified wedge for each wire rope size. Use of any wedge other than the specified wedge will result in an improper and unsafe grip.

NOTE: Refer to the Gunnebo Johnson Corp. General Catalog for complete safety recommendations, product specifications, working load limits, ratings, and sling configurations. For additional information or questions, call: 1-800-331-5460
