This isn't at all related to falling cranes and their center of gravity, but...

Not only does the bouyancy assistance disappear when the bus is pulled out...but the damn bus is half full of water and probably 50% heavier than otherwise!

Wow they got it all on tape i'm amazed how they all survived. They should have been smart and looked at what they were dealing with. Look before you jump.

The crane operator did one thing wrong...

You can't see it in the video, but it appears that the deck failed. A bridge deck is designed to take a H-20 loading as the worst case. That equates to a 12,000 lb point load (1/4 of a dump truck tandem axel).

The crane slowly let go of the load as it tipped into the water. That tells you the deck failed as the crane tipped. A crane like this can easily put much more weight on the bridge deck than that on the 2 supporting outriggers.

With some interest I have studied your website and I am happy to be reminded about some basic rules for doing business in this trade, which at the moment is facing many changes due to the present financial turmoil. The products to be manufactured with emphasis on simplicity, ease of operation, maintenance, and safety, yes I can agree to that and then sometimes I wonder if we are victims of the fast development of the technical world. The basic construction principles are the same but all the applications to be added (like the new remote control systems) are from another planet, often giving problems that are not related to the actual crane production. It seems sometimes that we are moving away from the solid business principles and are being ruled by a set of new laws, which are hard to follow and understand. These new ideas relate to anything from production to marketing and sales and if you cannot cope with them you are at a loss. In our company we have a set of two worlds one representing the good old school with a lot of knowledge and then the newcomers equipped with the latest and updated lessons from the schools but without actual business knowledge. How to bridge the gap?

It is interesting to note that load factors are often neglected. Happens a lot in aviation where pilots allow their crafts to be overloaded. Pete

I'm having my 16th birthday party and I'm making it an outside movie party with a big screen and projector. On the invitations I told my friends to bring their favorite movies because I don't know what we should watch. We'll only have time for one movie. Do you have any suggestions? It can't be rated R (Love ya, Mom!) Something that is actually a good movie without a lot of horrible profane jokes or cursing.

I was thinking "The Birds". It seems like a cool movie to watch with a bunch of teens. What do you think?

I want the recipe for an unsweetened vegetable cake. Similar to a
normal cake, but made with vegetables. I would suggest looking for
Sweet Potato or Zucchini cakes for starters.
