We have a dealer of former fleet and utility trucks, some with buckets, others with post augers, they are usually under $10,000, some are heavy duty. I think the limitations on these are the working range, like was mentioned by having to move the truck and soft ground condtions, but probably still an inexpensive choice when having to reach areas up high. I've always wondered how the safety systems, hydrualics, and electrical systems hold up on these units, there are a lot of surplus of these around. Probably a good buy, as once a fleet dealer saturates an area, the prices drop. I have extensively used just about the entire JLG line up of manlifts and scissor lifts. I've had many jobs with 5-6 various models in use for months at a time, including a few with several of the JLG 800 AJ's on site, which JLG calls an articulated manlift, it reaches 80 feet. They certainly save time and perform well, but still need hard level ground to work on. These are expensive to rent and or buy used, pre-owned ones, I would worry about the electric systems, more so on the scissor type lifts, all the pinch points. You can lift some things with these, we've done it, but really not worth the risk, and if you push it, you will blow out seals, as we tested the boundaries a bit, sometimes we needed to put a welder on a truck, so 5 feet up, a few hundred pounds, boom all the way in, no one in the basket, no problem for an 800 AJ, I think the platform on an 800 was rated for a 1000 lbs. Not sure what the guys did to blow a seal that day, couple hundred pounds a few feet up is one thing, probably best to just use them for their intended purpose. I had the biggest United Rentals could provide, brought into Manhattan in '03, it's listed in their booklet, a 250'-0" reach, truck mounted, over $2500.00 day + the operators pay, think they called it the brontosaurus, had to have my engineer do the math on the outriggers placement just to set it up, was a 3 story building under the street, had to locate the columns and displace the loads onto them. We had to get up close to 200 feet on a building to install architectural panels, the roof was a barrel vault so it was the only solution on this 10 story building. We used to set small scissor lifts with the crane on terraces and set backs to gain access to work areas, it's amazing what is out there today for high reach.
