    I don't know really. Coworker said 1/8x1/4 mile according to his odometer haha. I have not seen it all yet we are on a lower level. Had a 45ft JLG about full stretch to set the contents of our trucks on it.

    Here in Raleigh if the building has a white membrane roof the Canadian geese spend a lot of time on it. Talk about large,high piles of *&#!. Alot of maintenance guys keep snow shovels on the roof. I'd send a picture of one,but it' too disgusting, looks like a sewer treatment plant blew up on a 2 acre roof.

    Would be glad to have the flame roasted schematic instead of the massive wiring harness and all the wiring within a 1 foot radius around the two flame throwing transformers that is destroyed.

    What's your technique for setting that compressor in place? I have 8 CSHAs to replace on a rooftop and was denied a crane... I have a 40' man lift to get them on the roof but from there is looks like it might be pure muscle.

    If the building manager will allow it, we use a Genie Duct Jack to get the compressor up to the level of the unit. Then there is less He-Man stuff to do to get it into place. But you have to have a crane or a boom truck to get the duct jack to the roof. We use this technique when the RTU is too far from the edge to use a crane.

    Here is 3 ways:
    1. He-man that thing in there
    2. A couple 2x4s making two ramps, roll it up into it.
    3. Get straps or chains and go over the top of the unit and hook on the frame on the other side. I try to have it just long enough that a loop of the strap just barely hangs over by the electrical panel. Then I hook a come a long/chain fall/chain hoist to it and lift it in there.
