Any advice or expertise is greatly appreciated; I have found myself in a bad situation and am trying to minimize the damage as much as possible. I had sold the bid to change out a 10 ton RTU that was located dead center into the building complex, I accurately figured the cost of the job with the appropriate sized crane, labor, materials, delivery and materials... however one of our technicians had been sent out to field verify the supply and return of the original curb... as it was presently a Trane rtu installed onto a curb an adapter attached to the building curb. He had the curb adapter spec sheet and submittal and verified that it would work, and well he failed to accurately measure so now were stuck with a curb adapter we cant use and having to re-order a new curb. The Crane is just too expensive to send back out to the job due to the 6 hour minimum and at the hourly rate for that size of a crane and I need to avoid this option if at all possible. Currently we have the old unit removed, and the new unit set out 4x8''s I now need to figure out a away with minimum equipment and man power to move the new unit approx. 20'' over and lift it about 26 '' and place it onto the curb adapter ( PLEASE REFER TO ATTACHMENT / PHOTO ).
So what I am asking is anyone previous experience on what to do when the curb adapter is unfortunate ordered wrong and you have minimum man power in the area ( 3 guys max maybe 4 ) and you are attempting to avoid having a crane come back out for an additional 2,000$. I have been looking through sun-belts rental catalog and have found a high lift pallet jack that may work but I am unfamiliar with their operation as in if there is some mechanism they may assist in rolling or pushing the unit forward and if it would be able to support the 800 lbs the RTU weighs, other options may be using low profile jacks or bottle jacks or something of that nature to get it into place?
Let me know what you think my options are and what you would do in this situation.
