In this overview scene, we see they have already installed safety insulators on the wires that go east from the pole in front of the Domino sign.
I put a yellow rectangle around the end of the boom that caught my eye because the end was moving back and forth.
In this video of them installing the pole, note the clamp attachment at the end of the boom. It is normally folded down, and I had not noticed it until they started to use it. That is what holds the pole when they place it into the hole.
(new window) The fact that the boom has already swung half way around shows how long it takes me to switch the camera from photo-mode to video-mode when I'm caught by surprise.
digger derrick truck, a non-overcenter aerial truck, and an overcenter aerial truck.
When they were installing the new pole, one of the crew members explained that they would be back at midnight to move the wires. They had to move the wires later because they turn off the power to the neighborhood while they work on the wires. When I arrived around midnight, I saw six trucks in the area.
I believe the crew member in the raised over-center aerial truck is using a device to verify that the wires are, in fact, deenergized. A crew member is loading tools and equipment such as a crossarm, insulators, bolts, etc. into the bucket of the off-center aerial truck. I saw a label of "700 pounds" on that truck's bucket. I assume that is the maximum lift capacity. Note how the tool compartment has interior lighting. That is important because it is really dark when they pull the power. Not even the traffic lights were working. I was surprised how much ambiant light there was from store signs, etc. before the pulled the power.
