I sure could have used one the other day. Was using a standard telehandler and all kinds of problems. I did not know they made these. Remember we do not all work on job sites that are flat nor can easily get the machine squared up to the lift the way we would like to.
That's probably one of the worst places for one of these. They won't frame tilt like a standard telehandler, so a sloping site is pretty difficult, they have to get leveled up to work right. On a real steep sidehill going with the hill (cross slope, not up and down), I would rather rent a telehandler than try to get my 15 ton galion in there, simply because the frame tilts on the telehandler. The galion wants to roll over. But there are jobs I go do with my little 15 ton crane, that I couldn't do with a telehandler, simply because the galion can swing sideways, where there's not room to turn a telehandler sideways. If its flat enough to get it in there.
Its like every other piece of equipment, it has its place.
I don't think the rental house pushing these that I'm familiar with, will rent it out for one- two day jobs. They want month or multiple months, long jobsite rentals.
