Two of these little gems will be employed to raise the Lattice truss walls once they are assembled at their final location in South Wayne. Installing the lifting yokes to the top chord and rigging the pulleys on the ginpole was a good practice run that will be repeated and studied before the real thing latter this summer. The 3/8" to 1" scale model is just the right size for this.
A good critical analysis of the steps in the process will insure that the maximum safety practices are used and followed by all those involved with the raising. Safety. Think, what is the worst that could happen?
Puzzler - How many things could go wrong during the truss raising process using ginpoles? Will winches having a 2000 pound capacity each do the job?
