Raise the boom and lower the load. Dog everything.

Hand signals are used to transmit instructions from a spotter on the ground to the crane operator high above. Here is a poster illustrating those hand signals, courtesy of the California Crane School. Feel free to post it at your job site, or to have any of the images tattooed onto your forearms.

After a recent crane accident in Vancouver, what's most surprising to me is that, at least where I live, crane operators do not have to be licensed or even formally trained, and I'm sure it's the same for many jurisdictions in North America.

Yo Dog, I heard you like Everything, so I put a Whip Line in your Main Hoist so you can Lower the Boom and Raise the Load while you Retract Boom.

Witnesses report that the DJ was yelling something about "raising the roof" shortly before the accident.

I woud imagine that crane signals, like any other form of communication, occasionally have different dialects. I was a crane driver several summers through university, and while I recognize most of these, a couple are different ("hoist/lower load slowly" are different from those I was directed with, in particular -- if somebody on the ground circled his index finger over his flattened palm, I would have assumed he was asking about cake recipes).

Sadako Sasaki made 1000 hand crane signals.

The weird thing is that any of those gestures means something completely different to a crane operator if you're not striking a sultry pose.

Remember, site safety is priority #1. Always jut your hips to the right and show some cleavage to the crane operator. Otherwise, your "Dog Everything" might accidentally turn into a "Drop Shit Everywhere".

I don't see the signal for "The crane is toppling over on me," but since that signal is "wave your arms in a panic," it may not even be necessary to teach it.

Women use that "emergency stop" on me all the time.

I can't believe I'm hearing myself argue for more generic boring clip art people, but that poster is just flat out creepy. I guess I can toss Crane Operator off the list of occupations girls can do.

I looked less sultry and more sweaty in my dealing with crane operators days.

We did the point up and down while moving your hand in a circle to indicate raise and lower, but our other hand generally didn't get involved except for the more improvisational, "What the hell do you think you're doing up there?" gesture.

And you haven't lived until you've worked with a radio control bridge crane. Every so often they drop into "what if the Terminator forgot to take his ritalin one morning" mode.

I used to run cab cranes (not the giant boom cranes that build skyscrapers but the little five- and ten-ton ones that run on tracks and move stuff around inside warehouses).

It's a fun job. You get to sit around watching everyone work, mostly. And if they piss you off, you can drop extremely heavy stuff on them, killing them instantly.

Hand signals seem hopelessly old fashioned, but there were times when they couldn't be used.

A few years before my stint in construction industry, building a skyscraper often required the use of a hoisting engine in the basement of the building under construction controlled by an operator who was next to the engine. A cable or two ran from the engine to a derrick which was many floors above and not visible to the operator. A device called a "bell box" was used for communications between the foreman at the derrick and the operator in the cellar. The foreman pushed a button on his box which rang a bell on the operator's box. The code was something like one bell to raise, two to stop, etc.

Considering this, the red hot rivets they used to throw around, the lack of safety belts, and the beer for coffee breaks (actually written into the contracts) it's amazing they didn't have more fatalities.

Huh, I didn't know that a tied off half-shirt with exposed cleavage was OSHA compliant. Good to know, though; I'm gonna use this as evidence in my demands that we update our office dress code.

What mygothlaundry said. And here I thought the thread was going to be about the use of the "sexy lady" drawing on the crane poster.

"I didn't know that a tied off half-shirt with exposed cleavage was OSHA compliant. "

For a swamper as long as you've got steel toes, hart hat and high vis vest you are good to go. So as long as the shirt has the built in retro reflective stuff she's OK.

In my experience crance signals are a mixture of common sense and standard signals. Generally the operator does his best to work out what the lift controller is telling him.

In this case though, I every crane operator I know would be trying to do whatever the sexylady wanted.

Dont be too hard on the girl, at least she is dressed appropriately. There are some girls who wear the strangest things to do the gardening.
