Throwbag rope caracteristics

See what kind of throwbag ropes You find on the market. If you already have one: check which category it fits in and get to know a bit more about.

Coreless Polypropylene Rope

Strength 8mm:cca. 4kN

Abrasion test (see it here):  destroyed in 3 sec.

Cover:Polypropylene

Core: no core

Stretch:high

 

general comment: sorrily there are plenty of thowbag ropes without core on the market. Producers have lower production costs but does not mean you pay less. Your rope will be extremely weak and non durable. the advantage is: light and small. My advice is: Try to avoid these!

 

Shock absorbing high stretch Polypropylene ropes 

Strength 8mm: cca 5-7 kN

Abrasion test (see it here): destroyed in 3-8 sec

Cover: Polypropylene, stretchy braiding

Core: Polypropylene, stretchy braiding

Stretch: extremely high

 

general comment: the idea behind the stretch is to avoid the "big pull" when catching a swimmer. To use mechanical advantage or simply pull some pinned material is almost impossible. My experience is that even rescuing swimmers makes it a "Catapult". After absorbing the energy it gives it back. i personally would never use again, they are like bungee ropes.

 

Polypropylene Rope

(double braided and kernmantle)

Strength 8mm: cca 8kN

Abrasion test (see it here): 5-10 sec.

Cover: Polypropylene

Core: Polypropylene

Stretch: relative low

 

general comment: good ropes on the market, compared to the ones before, these are worth to buy.

Syntec and Spectra ropes (including dyneema)

Strength 8mm: cca. 16 kN (the most)

Cover: Polypropylene

Core:Polypropylene/Dyneema

Stretch: relative low

 

Abrasion test (see it here): 10 sec

general comments:expensive double priced ropes. If You have the money buy it! Still the biggest damage on ropes is caused by abrasion, so it gets damaged easily just like the other ropes. It does not give you a longer life or better resistance against abrasion, just a higher tensile strength.

 

WWTc Ropes

Strength 8mm: 1000kg (knotted 700kg)

Abrasion test (see it here):  60 sec+

Cover: Polypropylene

Core: Polypropylene/Polyester

Stretch:low

 

general comment: more durable and resistant rope on an affordable price, though it gets damaged just like all. The advantage is that after a surface damage it will hold until you finish your rescue as the core is extremely durable. The Polyester brings the heat away from the abrasion zone.
