Standing part
A rope generally made out of synthetic material that stretches very little under load.
Static rope
A separate rope that ground personnel can use to guide an object that is being hoisted or lowered.
Tag line

Technical use life safety rope
A floating rope that is intended to be thrown to a person during water rescues or as a tether for rescuers entering the water.
Throwline
Rope constructed of fibers twisted into strands, which are then twisted together.
