Expecting lots of Ha Ha's
You guys are talking about speed try this one.
We had a job to do increasing the weight of counter balance weights on a transmission line along the tracks in Saugus, Mass. Originally the engineers predicted that 150 lbs. of weight (3 only 50 lb. cast iron discs would be enough).They thought another cicuit would be installed on the opposite side of the pole in the future. It didn't happen.
The X-arms were sagging. We had a Condor telescopic boom 125'. The rental cost $6,000 per month and the least was terminating.
We panicked. The weather was calm and we had an operator, three linemen and a grunt. Once level we had to go up and do the following:
1. Ground the phases on 80-90 ft. poles (we tested for potential the first time)
2. Lift the existing 3 weights on each phase, remove the cotter key, unscrew the nut, lower the weights and add two = 250lbs., now raise it up and reapply the nut and cotter key. All three phases vertical construction.
3. Remove the grounds and return to the ground.
We took the bottom boom vertical and the top boom horizontal and just rotated and used the lower boom telescope feature to work it essentially as an elevator.
Total time (timed by the operator) from ground to ground was 13 minutes, no crap.
Some will say "your crazy" but imagine trying to do that off a ladder after we lost the Condor. Of course we were young and full of p--- and vinegar in the early 1970's.
