I have tried more than the recommended 3 wraps around the capstan drum- not much changes.Also have tried pulling harder, again no joy, 

best phone Sion @Treadlight Forestry then

 

BTW what rope are you using?

[Melton Martin]

I am using braid on braid 10mm polyester rope as recommended by the manufacturer. Yes, I pulling(!) hard to get the friction on the drum, and I have been using the recommended number of turns, which is 3 to 4 wraps around the drum - However, I will try more, but with too many turns around the drum I find the rope jams under itself then locks.......

 

I'll give it another go tomorrow and let you know the result......

I know it sounds silly but you need to pull the rope through with it ! It won’t do it on its own

I had that problem with self- mixing two stroke oil ...... left it on bench overnight next to petrol , still hadn't happened by next day     K

I'm using 13mm  as supplied with the winch (Ultra High Molecular weight Polyethylene)  .i'm unsure if the sheath is the same fibre as the core. I probably haven't reached the winch 2 tonne limit yet, perhaps I'll see if I can stall it when next out.

There's a spray-on product for slipping v- belts that increases grip. Maybe try that on the rope?

If its an offset capstan,.which some of them are , it could make a difference having it on overwrap on retrieve rather than underwrap .

Belt dressing. I've used it with some success on flat belts.

[Haironyourchest]

That's the one. Or maybe sanding the capstan drum to give it some more friction? Or glue something hard waring yet flexible to it, can't think what.
