Maybe a bit daft question.
I have seen pictures of the fairlead for winches with synthetic rope on. Apparently it is not necessary to have rollers on the fairlead? Is the maximum angle out from the fairlead the same? To me it is a massive improvement to have a smaller, much lighter and discrete fairlead compare to the classic roller ones. Can anyone point me in the direction to find some technical literature regarding the differences between the two types of rope “setup” and techniques? Any comments regarding this are most welcome

As Brendan says above
Synthetic ropes do not like the treatment they will get running through a roller fairlead Stainless (as below) or alloy

Stainless lasts forever (ish) whereas aluminium hawse fairleads wear away, especially in the corners.
There is a theory (mainly put forward by people who sell aluminium hawse fairleads) that the aluminium wearing away saves the rope some of the abrasion. Personally I use stainless as I've snapped ropes due to the aluminium fairlead rubbing away and allowing the rope to contact the edge of the winch mount slot. You can also use hawse fairleads with steel cable but roller fairleads are more common. When I used steel wire on my rear winch I used a steel hawse fairlead. Whereas you can use hawse fairleads with both steel and synthetic ropes, using synthetic with a roller fairlead isn't recommended although BITD when synthetic was first used we used to use roller fairleads - I even had a roller fairlead manufactured using nylon rollers. You just had to be careful when winching at an angle that might pull the rope into the corners. |

In a previous life before the advent of the www, I used to go caving and there was various bits of research done on SRT (Single Rope Techniques/abseiling and prussiking). Abseiling on ali alloy based rack bars/stainless steel rack frame or ali figure of eight descenders the ali components would wear and wear rate would be much faster if using dirty ropes. If a dirty rope come into contact with the stainless rack frame yes it would mark/abrade the stainless frame.. The ali bars we considered as disposable items and would either swop them around on the frame or replaced them. SEM, scanning electron microscope techniques were used on dirty ropes which had been washed. Whilst relatively clean the inside of the ropes contained small angular bits of grit and damage on the inside of the ropes could sometimes be seen. Personally I believe that it is better to have the ali components wear (which can be readily seen) then possible greater damage to the rope. For competition winching where winch lines are probably replaced more frequently then the leisure winching, yes I can see the need for stainless hawse. Like a lot of things there is probably not one ideal system to best suit for all people. Brendan |

Never seen one of these in the UK but potentially could help with spooling tension for wire ropes. Anyone ever seen one in operation? http://baprod.com/shop/towing/wirerope/cable-tensioners-guides/ |
