WIRE ROPE TERMINATION Resources
Field Installable Terminations
General Information
Electroline fittings are the first real advance in connecting practices since the development of wire rope. These fittings are remarkably compact assemblies of three basic units:
1. The sleeve, which slips over the end of the rope.
2. The plug, (see inset photo) which is inserted to separate and hold the rope strands in the sleeve.
3. The covering socket. The combination of these three units literally locks the rope into a strong, solid assembly.

TYPICAL ASSEMBLY
Working Loads
Electroline terminations, when properly assembled, will hold the “normal” or “rated” breaking strength of the IPS wire rope. They are certified by the “Underwriters Laboratory, Inc.” (Safety Appliance No. 799) to hold no less than 85% of the rated breaking strength of the rope. Fittings are designed for linear loads only.
Electroline terminations are NOT marked with a safe working load (SWL) as the termination is a component of an assembly which includes the wire rope. Due
to the many different types of ropes with which our termination may be used, the safe working load is dependent upon the type of rope and the usage.
Electroline terminations are designed to have a breaking strength greater than 6×19 IPS IWRC wire rope of the corresponding size. Our safety factor is 1.3 for the machined fittings and 2.0 for the forged types. How-ever, the rope is the weakest component of the assembly, and these safety factors cannot be used to determine the SWL of the assembly.
