Let me ask honestly....how easy is it actually to install double guy arms???? They look kinda complicated to install....
Silverliner14B   [Jun 10, 2010 at 04:10 AM]
I haven't seen how they did it in the past. Note there is a bar behind the pole that holds the double guy wires.

i think a Person Holds the Arm from the Fixture side...while another Guy Bolts the Arm mount to the Utility pole....then they Fix the Bar to the Pole....insert the Rods into two Predrilled Holes....then Tighten Nuts to Secure....just a Theory....we have some Really Old Double guy wire Arms like this....our newer ones dont have a Bar....but a Threaded Rod is Placed in a Hole Drilled in the Pole....and the Rods which have a Loop on the End have a metal Plate that is Bolted to make sure it doesnt slip off.

yeah two people or more......I know that Truss arms we have in my area IT IS POSSIBLE for only one PERSON to install it (without the fixture on it of course) simply put a big bolt on the wooden pole...then hang the truss arm with the very top hole...
then bolt the rest.....you are done! pretty simple huh?

Those forked double guys stuff seems more complicated and more involved...

Not Really....our Forked Double guy Wires use a Bolt Through the Pole...the Arm itself is a Steel Pipe with two Flat Sections of Steel Bolted to it...well its Flat at the End....but Bending so it gets progressively Narrower towards the part that Holds the Fixture....the Holes in the end are Slipped over the Threaded Rod...and bolts Secured.....the Guy Wires use the Same Bolt Through Pole Setup.

I know, PEPCO uses fork arms too...but its harder to attach it the pole without having to hold the whole arm to secure it...with Truss arms and tapered Elliptical simply first put a big bolt on the pole....then hang it (using a slide in hole...which is a hole that is bigger than the head of the bolt, and when you slide it down it goes to the narrower part of the hole) and it will be hung by one bolt, then simply screw the rest of the holes (in my case with truss arms in my area, total of 5 bolts..one huge bolts and 4 smaller ones.

With double guy and forked stuff....you'll need a 2nd person to hold the whole arm ... while you work on the mounting it.

Of course with us in truss arms, they do have other people involved, for safety....but it is possible to mount the truss arm easily alone....the truss arms around here on wooden poles are made of aluminum by the way

Remember back in the day when these lights were installed many didn't use bucket trucks. Yeah I suppose a truck with a small crane or something holding the arm while someone climbs the pole and bolts the arm and guys to the pole.

How are the Trusses Attached to the arm?...is a Truss Arm Welded together?
Silverliner14B   [Jun 10, 2010 at 08:03 PM]
Yes they are welded together.
GullWhiz   [Jun 10, 2010 at 09:38 PM]
Truss arms are already built together in one piece....so there are really no moving parts or easily bent part...while double guys (esp for forked style) would have to have some flexiblity on the forked part....plus if the guylines kinda gets loose or breaks...there's a good chance they will slide down.....I've seen such thing like that in PEPCO!

i Think Truss Arms are used cause they are so Stable..i notice they Sway Less than upsweeps,and Guy Wired Arms in High Winds.
