Lowering Device Project

[Theocus]

Have you found a retail outlet for the lowering device yet reg?

 

I have a job just perfect for this coming up and cant wait to get my hands on one!!!

I think definitely some of the retail sponsers on Arbtalk will be stocking the range Theocus. I only hope they are available in time for your job.

This device looks sick!

If you have a moment sometime, I loved to know more.

If there is some broucher or something that answers my questions, don't hesitate in redirecting me!

 

Could you run 19mm tri-braid on the double drum Reg? If not, what is the largest rope you've run on it? Do you find its bend radius satisfactory?

In a situation where a branch gets hung up on the way down, what stops a stiffer rope from rolling off the end of the drum? Is there a front catch? (I may need to clarify that more...)

Can the device it be side-loaded? Or does it need to be placed below the lowering point/re-direct?

Is the tension arm hard on ropes? Is the tension mechanism similar to an ascender?

How is the drum attached to the back of the device? What is this rated to?

What length are the drums? Do the drums handle heat well, or can you place ice packs inside them?

What is the surface of the drum like?

Where can I find more photos?

 

Thanks, keep up the great work!

Angus, the bend radius is +5 of a 19mm so it handles just fine, 2 at once if you want. When using a single the action is further improved by wrapping around both bollards, or so I’m told….less kinking in the ropes also.

 

In a situation where a branch gets hung up on the way down, what stops a stiffer rope from rolling off the end of the drum? Is there a front catch? (I may need to clarify that more...)

 

The last wrap is kept by the second shaft and has yet to fall off the bollard, although can be flicked off if a person chose to do so.

 

Can the device it be side-loaded? Or does it need to be placed below the lowering point/re-direct?

 

You couldn’t use the tension-lever if it were side loaded, so even a short a redi would be better in that respect. However, for straight-forward lowering it’d be just fine….although one would have to consider that a cut-in would become less effective as the line angle becomes tighter, hence the strap would bear most of the weight.

 

Is the tension arm hard on ropes?

Certainly nowhere near as hard as the bite from a knot holding a heavy log. FWIW, a technical guy from Yale cordage was quite satisfied with the way it grabs

 

Is the tension mechanism similar to an ascender?

No, its pretty unique

 

How is the drum attached to the back of the device? What is this rated to?

The Drums are bored right through the back of the device, so welded on the front and back. I think the WLL will be 3 tons using a cut-in. Although one would have to first consider the WLL or SWL of their lines.

 

What length are the drums?

Long enough for 4 wraps with a 20mm line. In truth I don’t have the exact measurements here as the devices in the videos and photos are just early prototypes. The final version which I only just saw myself the other week is quite a huge thing.

 

Do the drums handle heat well, or can you place ice packs inside them?

Sure you can, but the device comprises of such a huge amount of Steel that the heat dissipates quite quickly.

 

What is the surface of the drum like?

Hard

 

Where can I find more photos?

Thanks, keep up the great work!

Thankyou

Whats going on with the schwabish in this pic?

Whats going on with the schwabish in this pic?

Early version or a handy way of locking off the rope when lifting some branch/log?

Whats going on with the schwabish in this pic?

You mean the prussic Tim? Its tensioning on the right bollard at 5:1.

And here's a couple of photo's taken earlier of the final production models. Thanks

looks fantastic mate. whats the 3001 stand for? and i cant quite make out what it says on the end of the other bollard?

[Stephen Blair]
