I get a kick out of watching the house frame go together. The crane lifting trusses to start the roof framing is a favorite.
This is one that was going together near a new home that clients are having built in Grandale in SW Durham. I came by at just the right time with my camera to get a few shots.
The truss has to be supported properly. It will hang vertically all right when rigged right by the ground man. If twisted abruptly, the metal gang nails that join the framing members in the truss can be popped loose, and create the need for repair.
The ground man, the framers on the roof, and the crane operator have to work together. Obviously it is hazardous work, but good communications and teamwork take most of the risk out of the task. The ground man holds a tether rope that he uses to control the truss and minimize swinging and twisting in the air.
Done repetitively, and there will be a new roof under cover by dark tonight!
I have always enjoyed watching the growth of a new structure and the careful coordination of the operator, ground crew and others. The good ones make it look easy, which it’s not.
