In the tower industry Woop Signal system "Bang Bang" means drop a load all the way to the ground as fast as you want to. Typically a guy riding the line would give this command to the hoist operator only after he was well clear of the tower and had a clean path to ground.
Modern hydraulic hoists limit speed but the old friction hoists could drop you nearly as fast as gravity. Back in the day you only said "bang bang" if you wanted to fly to the ground at breakneck speed. Not OSHA legal, but back in the day it was a lot of fun!
Not sure but I think the term came from when you accidently dropped a load and it bounced, thus it hit the ground twice, "bang, bang".
Guy riding the line says "We're calling it a day, clear of the tower, Bang Bang!"
Hoist operator would kick in the clutch in and let the headache ball and whoever was on it free fall to the ground then engage the clutch at the last moment before impact.
In the broadcast tower industry a "wedding cake" refers to the gap between stacked TV antennas.
Man! That wedding cake didn't have any step bolts. How did you climb past it?
In the tower industry the term "Pork Chop" refers to a safety climb cable grab device that resembles the shape of a pork chop. (Funny how so much tower terminology uses food terms. When you are working on a tower for 12hrs a day you can't really be expected to climb down for lunch.
Hey, don't start climbing that tower without your pork chop.
