The tie beams are the large horizontal beams that form the base of the truss (the bottom of the triangle).  We have three to get into position.  Each probably weighs around 500 kgs, so they take some moving.

The first one is lifted into position above the kitchen using the telehandler.  No such luck with the other two.  We have to use a mechanical winch to lift these into position. 

In all three cases, the final positioning is done using brute force (and a sledgehammer).

This is the large tie beam (the horizontal beam on the bottom of the truss) for the kitchen.  This one we managed to get in position using the telehandler.  Unfortunately, the telehandler would not reach for the ones in the lounge.

A mechanical winch is used to lift the tie beam for the lounge truss into position.  Once at the right height, the beam can be wheeled into position.  Winches similar to these are used for removing engines from cars.

The beam is now at the right height and is ready to be manhandled into position.  The weather isn't helping.
