A real transformer

The big transformers for power lines are heavy.

  Notice how close that trailer is sitting to the ground?

Notice the number of axles that rig has?  Rule of thumb for load carrying capacity is 20K lbs (max) per each axle plus 14K for the steer...(sometimes more)..  so seven axles is permitable  to 6k x 20k + 14k = 134K  lbs.

Empty weight on that rig was (if I recall) about do the math.

That was a medium heavy transformer.

It takes a while to build those...and it takes a while to move them and install.

The electrical infra structure wasn't built over night...
