Depending on the type of rope several accepted methods are available.

Welding two ropes together is common in the steel industry. If properly done, welding may develop sufficient strength to complete the rope installation. However, the welded portion of the rope is rather stiff, and the welded steel wire material may become brittle. Since the welded portion has to pass over sheaves, there is the danger that the weld may break.

If installing Python® wire rope as well as all non-rotating types we do not recommend the welding procedure. Welding might damage the seizings and the rope may unravel getting damaged beyond repair.

Becket Loops
A common method for heavy crane rope installations. A steel sleeve only slightly larger than the rope diameter is swaged on to the rope end and a small auxiliary cable protrudes from the sleeve. Either, the old rope is furnished also with a becket loop, or the old rope will be connected to the becket loop with a cable grip.

Use of Cable Grips

The most common method to install a wire rope. The type of cable grip depends on the rope type and construction.

Non-rotating rope must be installed with a swivel between old and new ropes. The old rope may have developed torque during it’s working life and we must ensure that this torque is not transferred to the new rope.

Python® types Multi and Super 8 may be installed with a swivel. In fact, if you have to change either of these constructions for a 6-strand rope, particularly when this rope has a different lay direction, a swivel is of definite benefit.

Python® Power 9 and Python® Ultra must not be installed with a swivel. Doing so will unlay the rope and damage it beyond repair. Use two cable grips and connect them with an auxiliary cable.


When using cable grips, the end of the grips have to be tightly seized on to the rope body to prevent accidental slip-out of the rope. Alternately, you may wrap the grip end with a strong reinforced industrial strength adhesive tape.
