Bulldog OAR ascender/descender

[surveyor]

Hello all, first post. I have been building a climbing device I call the Bulldog OAR (Offset Ascending Rack) It can be used on a single line or a doubled line. I have a demonstration video.

An arborist has suggested that it can be configured with a hitch below also, which makes it tend slack nicely when the rope is pulled up through the hitch climber pull as shown in this picture.

Looks familiar.

That looks like remarkably similar to the U#######, but less shiny.

Looks nowt like the U%%%%%%%%. The chain links are positions differently, and all sorts.

It is similar to the Unicender, but it has all steel friction and holds the rope very securely once installed. It also releases differently. On a single line, when you pull the bottom arm down, with or without the hitch, the top two arms act as a friction assist on descent. It combines the features of a Uni with a RW and clamps on line immediatly when weighted.

Well it looks very well made from here, interesting stuff!

Thought I would update the latest development on the OAR. Here is a picture of this slack tending OAR. Because the whole device pivots, it allows the OAR to tend slack in the normal. The short demo video was filmed by my youngest son. manner.

It is very well made and very shiney!..even the video makes sense...but i will stick to my Spiderjack...

[Bing!]

Looks interesting.... Let me guess, not in the uk for another year or three, has to be CE approved (another year +) and will cost eleventy million pounds?

If your looking for someone to test it real world style send me a prototype and I will abuse it as a piece of shiny kit should be......

Seriously, I like the look of this.

 

Bing!

You have sold it to me, because it is made from steel, which will last so much longer than aluminum.

Are you going to be producing any black market/ ilegal one to try ?
