New to the GRCS

I think LJ means High Modulus fibre rope, such as Vectran. They are exceptionally low stretch and strong for their size.

I have several meters I use with a lug all winch for lugging round the forest when doing felling courses, because they are also very lightweight. Handy to use as a re-direct to the winch to stay in a safe zone. Best used spliced with hard eyes. There are drawbacks, depending on fibre. Such as UV susceptibility, flex fatigue and low melting temp.
 
Yes, high modulus ropes. I use Samson Validator II and Warpspeed. The spliced eye is covered with a piece of the cover from a dynamic rock rope, locking brummel forms the eye with a long bury.

With the cover covering the core, we fended off UV problems.


As for a "hard eye" I assume thats a thimble, which I didn't use.
 
A question to you GRCS users...

How fast can the unit hoist? Does the drill attachment increase the speed of the winch, the torque, or both?

The application I have in mind is standing up horizontial limbs from over a target. We've been doing this (with great results) by using our Boxer mini skid with the bollard on the Branch Manager.

winching with the drill does not in itself increase the speed of winching. The winch has two (2) speeds. To make it basic, winching one way is faster, less torque, the other way is slower, more torque.
So using the drill is faster in the sense that the drill is mechanical and spins at whatever speed the drill spins at and does not get tired of cranking like your arms would.

The drill that I use is a 3/4" chuck, Millwaukee Hole hawg. This drill has enough 'grunt' to spin under high torque loads and is two speed (forward and reverse).
I use the drill to winch limbs from horizontial to vertical, winch folks up into tall trees, winch loads out of ravines, pretension load lines, etc.

Using a mini-skid to take up tension on a line could be very dangerous as you dont have a good 'feel' for how much load you are exerting on the load line. You could very well overload the tie in point or even cause failure of the load line.
I could not do ANY of these jobs without the GRCS
