The term "wire rope" is used in this module, ratherthan "cable," to avoid any possible confusion with electrical cables. To determine where to apply seizing wire, measure socket from bottom of socket to the top of the bowl. Method one: One end of the seizing wire is placed between the valleys of two strands. Wire rope is designated by the number of strands, the number of wires per strand, and the rope diameter. Any time wire rope is disturbed such as in splicing an eye, the strength of the rope is reduced. By following the procedure below, the splice can retain from 90% to 100% of average new rope strength and in used rope up to the same proportion of residual used rope strength. Measure, cut and prepare wire materials for splicing and fitting swaging. This is how the haul rope is tensioned. Step 12 Step 13 After both splice ends have been tapered, it is necessary that you smooth out the splice. This . A-5. Wire rope splicing is essentially the formation of a knot between two parts of the same rope or between two separate ropes by separating and unravelling the strands and interweaving the threads together to produce a strong joint.

When managing the electrical project, you will often find a need to splice electrical cables instead of buying new ones. Unlaying the strands of the rope. The methods of making all four types of splices are similar. To provide corrosion protection and lubrication in the core and inside wires and on the exterior surfaces. For example: a 1 1/8" haul rope and a 1 7/8" track rope for a bicable system; a 1 3/8" rope for a monocable system. A short splice. Carry out splicing using approved methods and procedures. This will be mark "B".B Step #3 Press prongs of fid into cover or center just behind tape. 1. Insert the wire rope in the terminal. Modern synthetic materials, however, tend to be slippery and, now, a minimum of five complete "tucks" is recommended.. Pros and Cons: The Short Splice makes a secure join between two lengths of three-strand rope. For ropeways, wire ropes are made into endless loops by using a "long splice" procedure, or terminated by attaching an end to a carrier, anchor or counterweight using end connections such as sockets. the rope with the first strand, and then cut off where it emerges from the rope. As a matter of fact, the present method can be used for splicing wire rope having no core . Tightly tape end of braided cover or center after extraction ( STEP 2 of splicing procedure). safe job procedures for inspecting and replacing wire ropes. The seizing wire should be soft or annealed wire or strand. Making a loop or eye at the end of a rope so that it does not have loose ends is also called splicing. Form 12-11 E, requirements for FM 5-125, Rigging Techniques, Procedures, and Applications (Qty rqr block no. It can be used to construct a loop/eye at the end of the rope (a back splice), or to tie two ropes together. Place the first group with the core on the right as you face the "Y" formed by the two legs. There are over 234 different types of splices, but as long as the splice is strong and does not draw out under stress, it will serve its purpose. This manual contains simple how-to instructions for splicing on cable yarding Cutting Wire Rope . A wire main core shall be split up and the strands or, the wires shall be distributed among the tucking tails, and tucked with them for five full tucks, then the core shall be broken off at the completion of the fifth series. 2: Twist the two ends of the seizing wire together, alternately twisting and pulling until the proper tightness is achieved. (Fig. Press wires against the cable as depicted and slide 3/4" Dia. They can be easily pulled underneath loads due to their small conical shape.
