Any thoughts on how to resolve this would be gratefully appreciated.

thanks in advance for your help.

We would probably roll the beam into position on scaffold tubes, it is
amazing the loads you can shift using this method. Once in position, we
normally would try to use Genie lifts to get the beam up to the correct
height, then scaffold up underneath the beam to support it, lower it
onto the scaffold (pre-greased) and slide/ turfor it into final
position. If the ground the genies are on is really good, i.e. decent
flat concrete, we would use the genie's to just roll it into place
rather than slide it. The scaffold is there then only as a safety
feature in case of a problem.

This is the type of lift I mean

==================================
With care the same result could be achieved by using conventional bottle
jacks - readily available with 20 ton lift. It might be necessary to dig
holes under the beam to position the jacks for the initial lift.

Jacking would be preferable to hoisting because no heavy overhead
structure would be needed to support a winch.
