Two gable ends complete with crane triangles cutout at the top. The one raising and setting wood trusses wood truss building construction is pretty much what i had in mind in my post above.

Is there any rule of thumb as to when it s best to use a crane to place trusses on the wall or whether it s okay to not use a crane and just lift them and place them by hand. Set the heel of the truss up on the wall on each end. The walls are about 10 feet high from the ground. Screw fix a c16 structural grade timber 150mm x 50mm length to the face of the truss pack.

This is because cranes are specifically designed for the task of lifting large and heavy loads. The outside dimensions of the structure are 22 ft x 26 ft. Crane lift the truss pack onto the wall plate. When the truss is in place a quick pull of the unlocking cable by a worker on the ground releases the truss.

This is due to improper techniques that can overstress the truss and its connections.
