Most folk have many blocks....Colby....I do and numerous rings to mention...but sadly no GRCS...awe man...I think I am a loser....

Yeah, you rich longtimers... :)

I've got two blocks, an omni 2.0, and two ring slings. I often put the blocks in the tree so I can switch my terminal rigging point without swapping the rings out for pulleys, and the slings on the porty/grcs side because I'm less likely to need midline attachment there. This dude be like "I got blocks at the bottom and I'm on a boat with diamond falling from my open hand", lol.

So, I'm wanting this information - with the forces coming in from the side instead of the top, do you have any problems with the grcs rotating around the tree, and do you think that's an issue in real life?

I do believe this is a real life issue... But as long as you stay within the working limits of the GRCS, and it is mounted properly and in a stable position, I haven't had any issues. The pull is also pretty tight against the backing plate so it really doesn't have all that much pull on the device. Also the strap tension is key anytime it gets mounted.
If I mount it redirected off to the side and I don't like the way it comes into the side fairlead I throw a block or my large pulley on top. Its important that you are able to roll with what you have in front of you in our industry.

My upper ones fell apart under the strain, putting the metal bolt heads that retain them on the grcs frame in contact with the bark of keeper trees. It's a lot like spiking the tree and gaffing out. I had a spare 1' section of 3/4" multiline II from a rope swing installation and chucked it in there across the top just before the f8nal tightening of the grcs strap - works like a charm.

I like the rope idea as I've been through several top rubber feet. Seems they really take a beating.

I'd like to see a photo of what you are doing.

I carry my GRCS in a six gallon plastic milk crate. Works well and the bollard sits so it's not contacting any of the the steel parts. I seldom use the fixed aluminum bollard.

Greg thank you for the contact. So far this evening everything is working well. It hasn't logged me out yet. May just be my crappy net provider .... service... satellite connection. If I have any additional issues I'll look him up.
Thanks again,
Craig

That's the same milk crate I am looking at. :D
 
One caveat. If you've purchased the truck mounting kit that slides into your receiver, pop that baby in and make sure everything lines up. I took my shiny, brand new GRCS to a job site, intending to mount it to my truck, only to find that the holes in the truck mount were drilled about an inch further down the bar than they should have been. This made it impossible to put the truck mount far enough into the receiver to lock it in with the hitch pin. DOH!!!!! Fortunately, there was a tree to mount to, for the pulling task, and about a half hour with a sawzall and a bi-metal blade and the truck mount was reduced to the correct size.

The visor plate is a good idea. It makes for a much more solid installation. I've ruined and replaced the feet on my GRCS enough times to have thrown one in the Treestuff shopping cart but for some reason it never happens. Thanks for the reminder.

On a removal, just saw a flat spot onto the trunk with a 1" lip on top to catch the frame. This works quite well. I bought the visor plate and have never used it. We rig big when we can...

I tried that sawing technique once and found it awkward. To be fair, I only tried it once. It was hard to saw the flat spot, and I made the lip too big and the rope was rubbing against it. Felt like the newb I was. I like the sound of that "screw it into the tree" technique.

I'll have it out again on Tuesday if you really need a picture. It literally just sits over the rubber pad holes, between the mounting plate and the tree. Extra rope gets in the way, so I just use a 1' length.

It's gotta be just deep enough that it catches the mounting plate behind the pigtails.

Lags would work better, but it's a bit of effort, and tools we don't normally carry. I don't think most of our ropes will meet the load that justifies lags.

Have you watched the Volvo video?

I've watched the video. How much do Volvos weigh?

Good question.

I checked early 90s Volvos which weight 2,800-3,500 lbs. While I could easily see tree parts weighing that much, it's well in excess of the working load rating of the GRCS, at least for catching loads.

If I recall they dropped the Volvo into it pretty hard. I've pushed the limits with lifts on the GRCS, and not had the GRCS significantly shift.

I've watched every video I could find on the GRCS before purchasing. The durability along with the capstan winch Is what sold me. I investigated the Hobbs unit also which looks like you could rig a Mack truck downhill without brakes but the GRCS winch got two thumbs up from me. I haven't used it yet but I'm looking forwards to 'playing with it'.

Gotta get a milk crate for it. We just have a hand on the frame and another carry the bollard... i think the fixed bollard is on the truck, but i haven't used it for the entire year and a half i have worked at this company.
 
I packed everything in the 6 gal milk crate except the aluminum bollard, which I will pack separately and leave on the truck until needed. It's damn heavy all in the crate. Although not two bad with two people carrying it. Even if the crate gets left on the truck, it still is great for keeping it all together and organized.
