Rigging (in this context) is the act of safely supporting and transporting machine tools.
- Twisted rope has a much higher sliding coefficient (ropes are rougher). It can take a lot more static tension to overcome sticktion.
- This makes it harder to “synch” up the rigging before hoisting the load
- Twisted rope frays more easily; more rapidly loses ultimate tensile strength when it frays
- Harder to spot damage on twisted rope
- Requires a much larger bending radius
- Unwinds when a load in placed on it, unless it is anti-rotational rope; automatically gets longer when it unwinds
- Knots can reduce the ultimate tensile strength by a huge margin
- Nylon or other man-made fiber webbing is much stronger
- Nylon can degrade with exposure to UV light, oxygen, some acids, solvents with long exposure
