I am with Ryan here. I will use a running bowline if I am improvising a hitch with a short section of rope. Directional loading is one concern, but for me it gets loose when not loaded and the Porta wrap creeps away from the tree. I hate any more slack between device and tree than absolutely...
I have always explained it this way. Both Hobbs/GRCS are great devices.
If you lift a lot and lower heavy a little the GRCS is an excellent choice
If you lower heavy a lot and lift a little, then the Hobbs is an excellent choice.
When I say lift, I mean all facets of using the winch.
I...
In many years of rigging and lowering, having to worry about the lowering device heating up to the point of it being an issue has not happened.
In the early years, before mechanization, the cycle was slow enough to allow the device to cool. As in when we got to heavy wood, by the time it...
Stainless may dissipate heat slower, but I like the less wear and less corrosion factors over other metals.
I will manage heat through load and technique.

My neck of the woods, street and traffic lights are changing over to 110/120v as they are either replaced with LED’s or new construction.
No difference really for me and tree work though.

My experience is much the same with the hastings. You set a voltage range and work your way up or down. For 120-240 the unit is all but touching the wire. The higher voltage the further away it detects it.
I have picked up voltage on fences, downed comm lines, and the like. Never on a tree...
I have used these and they work well, are easy to use.

I am sure you have a system that works for you.
In talking with a lot of different companies all over the place, I find that when working the calculations many forget they pay a team member to mix. Often you are paying your crew lead as it is his/ her responsibility. We don’t break pay down to...
Don’t forget to factor in paying someone to mix it! That was the game changer for spending extra on the premixed ( we use Trufuel). Resale is higher as well.

I agree here any any worthwhile EHAT program would address these things as you put them.
I know I do when I teach and when I train others to teach. I would add the caveat to all the above, “ with proper inspection”. I have seen triplex short and weld shit together when prodded, lifted and on...
I see your point but you are lumping all Arborist electrical hazards training into one unfair category. Just as you did earlier in the thread when you said all EHAT for arborists is based on fear. Again I understand your viewpoint, but caution about overgeneralization.
This is not to pick on...
I can understand the point that the coating is both. However, in conversation and working with linemen in both the USA and Canada, I have never observed one work with or on with out appropriate PPE.
In essence we have two interpretations and I am fine with that. A interpretation for those...
Bart,
That is weather proofing on the service drop you are speaking of not insulation.
It is a small point, but I find when you realize many features of the electrical distribution system are designed to protect the system and not you, your mindset changes for the better.

Before the advent of reliable systems that were SRS and allowed for safe work positioning, there were many variations on what you are proposing. As a comp climber for 12 years and a 20 year ITCC volunteer, I either tried or saw most the the good attempts.
In the end, an in-line loop knot...
Why tie to the device that has not been tested to that use and is a point of failure, when you could just tie al suitable in line loop? You are trying a knot anyway.
