balancer---spyder line?

[Stumper]

Butch, it isn't a lift-it is a lowering op.

 

[Zac]

Are those 'biners choked Mark?

I wouldn't use two slings for that lowering op.

Yes. Steel, 50 kN.

One sling with an adjuster.

 

[treewhisperer1]

do you have a close-up of the adjuster?
how is it set up? Looks like a great setup, quick to attach.

The balancer itself is 5/8ths inch Stable Braid, the adjuster is a spliced loop of 1/2 inch Tenex, the carabiners are steel, double-auto-locking, 50 kN.

If these photos are too big let me know and I will resize them.

Why not use 'spider legs'? No adjustment is neccessary. No links to worry about improper loading.

If you are using links, a screw pin shackle would be my choice. They are designed to be loaded as in the attachment.

To me, the advantage of the Spider Balancer comes from not having to call the CG to hitchpoint so exactly to get balance of horizontal carry. But rather, just get CG between the 2 hitch points; much easier guesstimation. With prussik you can make one leg shorter than the other and carry not just horizontal balanced or vertical hang, but at a slant.

i prefer to mostly work without crane; and use the tipping over from horizontal growth to vertical hang as a helpful(even if need to roll to side to get same effect), automatic pretightening of the line before actual tearoff from the hinge; for low/no shock rigging. Or reverse to facecut topside and backcut under spar for crane to pivot to upward vertical('upwards felling'); then cut free when vertical(perhaps last 15 degrees of lift kerf dutched in face/closed on heavy side for better balance /serving to crane). Very few times do i see it necessary to be able to balance flat; without hinging down or over, into vertical hang. Like lifting large, sprawling horizontal growth straight upwards; then over/out to get out from 2' over aluminum and screen enclosure; yet under other branchings to remain etc. (Then need more than 2 legs; and more nerves too

)

We use those too. I was just showing a photo of what Nick and Phil were discussing.

You're right, shackles are stronger. But, 'biners are faster. The log in the attachment is the max for that setup (and only if it is a static lift). Anything bigger than that we use shackles or knots.

 

[Colin]

No spider legs here. Why use em?

 

[Riggs]

Why use em ? hmm , in that picture I wouldn't either . The times when it matters most , when all is not in the clear . And you need to look in charge , you have to use them . Why wouldn't you use them ? Some times I just do it to let people who know no better , how cool I am . Wow he used five slingamathings!

 

[Colin]

I like to use them when I'm in close proximity to a target.

Really nice, functional gear.

 

[chris_girard]

I think this was discussed elsewhere in another thread, but don't some of you guys use Amsteel line for spyder balancers?

I know that stuff is incredibly strong.

We use em. Mostly for working around energized lines, tho. Amsteel is dielectric. It depends on the application; do we need a low stretch line like Amsteel or will Tenex work? For spider legs we use 1/2", 5/8" and 3/4" polyester hollow braid (Tenex, Yalex, Nerex). Amsteel is pricey, but well worth the investment. I have some 1/2" Amsteel legs that have been used well over 150 times.

 

[chris_girard]

Norm do those Amsteel legs have spliced eyes in them or do you just use knots to attach them.

Hey Mahk, could you give me the lengths of the balancer and adjuster that you're using in your photos? What do you think would be an all around good length to use in most situations.

I'm still not sure which one I prefer to use, individual spyder leg slings or an adjustable balancer.

 

[overpaidmuniguy]

I put together a spider leg out of 3 strand, nice & easy splice. It works great as long as you don't forget what it's made of. 3-Strand grips great on braided lines. Certainly a cheap solution.

 

[Tom Dunlap]

At one time I had a four leg spider sling. Since there were 4 legs any combo could be setup.

The white slings were tied using Klemheists for adjustment.

A sling would be choked around the tree and a biner/shackle used between that sling and the white adjuster on the spider.

The four leg only cost me about $35 as a discounted setup from an industrial rigging company. The white slings were not very expensive either.
