"Not Intended for Fall Arrest"

Re: \"Not Intended for Fall Arrest\"

"You wear fall arrest (harness)in a bucket and work positioning (saddle) in the tree."

Right. But still, I've had small twigs snap in the tree as I was climbing, and fall a couple of feet. Are these new saddles not intended to be able to absorb that type of shock? Ideally, I don't ever fall. But many saddles don't have the asterisk* that the Sequoia and other new saddles do.

Know what I mean?

That's what climbing ropes are designed for; to absorb the shock. They are 'dynamic' ropes. That's why it's important that we all climb with a dynamic climbing line designed for arborists.
 
Re: \"Not Intended for Fall Arrest\"

I dont know how the anchor point strengths compare but I think a lot may have to do with the position your body is in when you fall and how the harness displaces the energy. I see this as more the reason than weight capacity and tensile strength. Just my thought.

The other difference would be a climber is already partially loading the harness where as a bucket operator would create a much greater load to the system.

I do like Tom and use a Screamer in my system...saves the back from most of the impact as well. Cant remember the post, I think it was about the Unicender?...
 
Re: \"Not Intended for Fall Arrest\"

During one itteration of my Uni tether I used a Screamer.

If a climber were going to be working in a situation where a fall might be considered it could be a good addition. Breakaways are NOT a good idea for working around electric lines though. If the climber falls it could make matters worse if they fell further into the wires.

Royce,

Fall arrest harnesses have to be full body to allow for higher positioned attachment points to prevent inversion during a fall and are subjected to harsher dynamic tests than work positioning harnesses.

Your typical tree work harness will be tested to take a 100kg torso dropped 2m in a factor 2 fall plus a static pull test to 15kN for 3 mins, a fall arrest harness has to take a 4m factor 2 fall in both an upright and inverted position.

Your harness is plenty strong enough, all you have to do is keep your lines tight and don't climb above your anchor point.

With regards to the Navaho; it's the same as all the Petzl gear - good. There are better and worse harnesses out there.

On the topic of the Sequoia saddle, does anyone have any input/real life reviews on the saddle?

Thanks

I have the sequoia I love it its lightweight, comfortable and functional although i am thinking of changing the bridge to a rope bridge
