Hello to all. I have been posed an idea by my brother, who comes up with some crazy stuff, about an electrical lowering device. I was curious if there was one in existence or if anyone thinks this is a good idea? Personally I think he's just pissing in the wind per say but he's all ready to go and try to build it. He figures he'll have around $1000 or so in building it. He wants to use some kind of winch as the cam deveice I belive like the GRCS uses the boat winch. The winch has a remote I guess that can be used up to 80 ft away so you could in a sense tension the line from the tree if you didn't have a groundy or your ground guy was busy elsewhere. I can see how that might be beneficial but I think that the weight of such a device would be very cumbersome. Also if you're using it doing rigging by yourself if if you used it to pull something back off a house or for some other reason needed to pull something you'd have to come out of the tree to untie the piece and then climb back up. Also what happens if you drop the remote? I'm sure some of you guys have thought about this looking at the hobbs and grcs. So do any of you guys have any thoughts to support this or to help me try to persuade him to stick to the porty he has and get a 5:1 or something like that tree pulling set up?

Make it battery powered and have the bollard rotate under load so the energy from the lowered pieces charge the battery.
Traditional lowerer devices like the GRCS, Hobbs and Porta-wrap dissipate this valuable energy as heat resulting in rope wear.

Batteries would be too large and heavy to work in a remote/up in a tree.
What would the advantage be to having the winch up in the tree instead of on the ground and running the rigging through a block like is used now?

Rigging without a groundman?

Tom,
The winch would still be at the base of the trunk. It would be the same type of concept as the GRCS or Hobbs with the winch. The winch would be electric battery operated and would have a wireless remote that you can take with you as you climb to control the winch in and out.

If Mike Poor can fly his boom truck wireless this concept seems quite simple and similar.

If you have a groundman down there anyway, to untie pieces, why not just communicate with him by voice, and let him control it?

Battery acid and rope fibers don't mix. If it's AC powered, you have an electrical hazard.

Battery power wouldn't be the best solution. The motors that are used are similar to starters and draw lots of power. They could be mounted remotely and in proper containers.
I have a 12v winch mounted on a skid that slides into a 2" receiver hitch. When I put the unit together I had a battery shop make up a 'jumper cable' with a short ground cable that clamps to the frame and a longer hot end that clamps to my battery. the vehicle has to be running to operate the winch.
Using GFCIs would eliminate the electrical hazards.
