Qonox, "pulling" is a fairly generic term. You might hear a blaster say that he is going to design the blast to pull a particular wall away from an adjacent structure, so pulling is used throughout an imploded structure to get it to fall where the blaster wants it.
Wolf, I have used the term "hook" or "hooking" during dismantlement jobs to loosely describe the different lifts and picks involved. Are you talking about a firefighting term?

I may be speaking "out of school", but I don't think the term is necessarily beholden to explosives use. Yes you can "pull" a structure away from adjacent buildings while performing an implosion, but you can also "pull" structures during conventional demo while using either the machines or a combination of cabling and machine force. So it does include implosion as well as all other means of conventional demolition.
So "pulling" can include explosives, but in that sense it's a certain technique for forcing the building away from adjacent structures?
In other words, you would never "pull" a building to have it fall into its own footprint. "Pulling" is used to force the building to fall in a certain direction. Correct?

Thank you for that. But just for clarification, does this "pulling" include implosion by explosives?

"Pulling" is a commonly used term. Check on the many documentaries that quote many people say they are "pulling" a building away from an adjacent exposure.

Keep this Forum clean as you never know how we may influence a young person who aspires to be like blasters or demo guys.

One more thing though: I assume you all are quite experienced in demolition? Yes?
I've been at it for about twenty years but I'm learning new things all the time. I'm sure there are some on this forum with much more experience.

Okay, thanks, guys, for your responses.
Yes, I was referring to WTC7 and Larry Silverstein's term "pull it". I understand it to be a firefighter's term and not one used in demolition to mean an implosion by explosives.
I participate in a 9/11 debate forum, but I do not wish to turn this thread political, so we will end it here.

When a building is precut and pulled it is every bit as much a work of art as an implosion.
I watched some guys from Cleveland Wrecking pull down a building once that was probably 140' high and probably about 200' long. It was slicker than whale shit on an ice floe!
I know, but we wanted to have him come back 
I posted the above due to the fact that I have received many e-mails in the last couple of months and particularly in the last week or so about the term "pull it" in the terms of demolition.
Recently the forum has had several new members trying to start a threads about the collapse of the WTC1, WTC2, and WTC7, that it was a "controlled demolition by explosives
Sorry, James we were pulling his leg.:)
Seriously though, Qonox, in conventional demo we do "pull" some structure or portions of structures. Sometimes it's easier to do than other methods where you would have to work at height with a machine or a crew. A lot of the same principles of motion that you would use in an implosion apply, you just aren't using explosives to initiate the movement. You generally need more room to drop things by pulling since you aren't effecting a total failure of the structure.
[FONT=Verdana]I think what Qonox may be asking is that a lot of websites are referring to the collapse of WTC7 and what was said right before the building collapsed was
