Big component installation head scratch

[gravitate]

Hi. we have a building with a 5m x 4m opening in the side directly next to a road. The opening is for a big 16T chiller unit. The problem is that inside the building there is nothing to lift off and also the chiller has to go on a plynth that is just inside the opening. Has anyone got any ideas how this can be done at all?
Thanks.

How tall is the unit, and what is the height of the plinth relative to the lower edge of the 5mX4m opening?

I think an experienced heavy machinery rigger would have all manner of low profile devices to support and maneuver the HVAC unit.

probably take some prep work creating a "ramp" (slped or flat) from outside the building to the plinth.

the OEM should be able to say if the chiller frame or base is suitable to bear on pipe roller directly, but it may be as simple as securing an oak plank or a length of heavy angle to each side rail.
The few units I've dealt with have had stout pockets for fork lift blades to pass thru. They may offer some possibilities for the use of side mounted dollies if there is minimal head room

the plinth is 250mm high

Our normal heavy rigging contractor would take care of this. They would probably set up cribbing and steel plates outside the door. They would set the unit on special rollers and roll in into position along the steel plate and onto the foundation. They would have some appropriate method using jacks to lift the unit just enough to get the rollers out and set it down on the foundation. For some of these moves, they have brought in special heavy-duty fork-lifts and picked the equipment directly into place. A plan needs to be developed before the equipment fabrication is complete in case additional lugs, jack-blocks or rigging points are required.

Contact a rigger, they make their living doing just this sort of thing every day. I had them move a 280 ton machine almost 300 feet through a working shop, avoiding all the posts and making several turns along the way. Then they lifted it with only a couple feet of overhead space and shifted it in the air almost 15 feet to it's final position. All in a days work for riggers.

JJPellin has the right approach, get a rigging contractor. Some of these riggers have even made large holes in building walls to get equipment in place. Use a PRO.
