Dyneema Winch Rope Vs Steel Cable

Been using dyneema rope on offshore winches for 20 plus years.

Dyneema winch rope vs steel cable. It is also needs more maintenance once there is dirt in the rope as it goes under strain the dirt will sever the fibres so keeping it clean is important. Rope breaks heaps easier than steel cable. Plus the d d ratio of a sheave is less than half of steel. Consider what 1 2 steel cable weighs in comparison.

Standard drum winches traction winches best stuff since canned beer and sliced bread. One guy can pull 150 feet of 1 2 dyneema tight. Synthetic rope is even mandatory in many big sanctioned off road events. They re 4 times lighter in weight than steel cable and don t store kinetic energy like the steel cable does.

So if the cable breaks it will not snap as powerfully as a steel cable does. Though the synthetic winch rope has a higher breaking strength it is breakable. Pound for pound dyneema fiber rope is up to 15 times stronger than steel and up to 40 stronger than aramid fibers otherwise known as kevlar rope. Ever imagine dragging around a 6 steel rope and end fitting.

The high performance strength and low weight of dyneema rope ensures that it is safer to use than steel wire rope.
