Spotted this a little while ago while out at lunch. Comcast contractor doing some work, drove about 400' with the tech in the bucket as seen in the pic. Didn't have a chance to get it on video, but they moved up the street from one pole to another.
I know that some lifts are specially modified to allow this, but this didn't look like anything non-standard.
An aerial lift truck may not be moved when the boom is elevated in a working position with men in the basket, except for equipment which is specifically designed for this type of operation in accordance with the provisions of paragraphs (b)(1) and (b)(2) of this section.
very bad idea... anyone who has operated a boom lift (such as genie z or s series) knows that when you hit a minor dip in your path your basket will nearly catapult you... the time you save in not lowering down and doing it properly is not worth it...
Yes on the boom and no on the scissor lift. To my knowledge it's optional but scissor lifts are considered portable scaffolding with a railing. In a boom lift a harness is required and the tether type has many conflicting opinions. I use a fall restraint to keep me from going out of the bucket on an unforeseen bump. A fall arrest would typically make you fly further once it unraveled after impact.
One summer I spent a lot of time driving an offroad lift around what was going to be a parking garage relocating a bunch of voice, data, and security wires which ran through the area. Even with the bucket down, going down a slight incline could get a little scary.
On level ground, though, I've moved even very large (55') buckets while up in the air. Most aerial booms are regulated to a crawl when the boom is up, but I don't think that there's anything stopping a truck like the one in the topic here from moving.
Yes, common and sometimes necessary. Cable placing bucket trucks are made for this, they have stronger components than normal service type bucket trucks and an intercom between the basket and the cab. Many cable placers have a reel carrier on the back of the truck as well to pay out the cable as its being installed in wide open areas.
In aerial construction, the first thing that goes up is the strand cable, typically 1/4" steel. Once it has been tensioned, the fiber/coax/copper is lashed to the strand. In congested areas with lots of other cables or other obstructions, the strand, cable and lasher have to be threaded over, under and around them. A moving platform makes this job much easier.
or just use a helicopter like this... https://www.youtube.com/watch?v=sh_Gch9Xwto
