Q: A few years ago, my college decided to take down two multilevel dormitories. The demolition company decided to take it down piecemeal with a wrecking ball. The wrecking ball was attached to the crane via a very large tire (just the rubber part, not the inflatable part). I have seen this done on normal cranes and other wrecking balls on TV and was wondering if any professional construction people out there know why they would do this as to me, a guy not in the construction/demolition business, think that might be a bit unsafe.: Shock absorption. The ball swings toward the building and hits, the energy of that swing is mostly dissipated into the building but also into the cable and cable connectors as the ball bounces back. That shock of the impact resonates and gets dissipated by the tire. It reduces wear and tear on the cable and cable connectors, also on the crane tower. Your car engine has motor mounts of the rubber type of material and it absorbs the resonating vibration of the engine. I have seen the cable connectors, interesting to say the least. The strands are interlaced sometime, and other times I see them clamped together. It would seem important to protect those joints. I do not know all of the crane business terminology, but that would be the gist of it.

Q: DENNY CRANE!: The only Denny I bow down to serves awesome coffee and a grand slam with all the syrup I can pour. What do you got?

Q: i need the names of the organisms. like names of insects or fish or what ever they eat. give the organism's name. don't just say fish or insects. i need specific names.this is for a biology project.: Diet okorder /.. I'm sorry, I couldn't find any specific names, but here are some general ones. Sorry again.

Q: Ok I got these huge mosquito things in my house and found out they are crane flies. I got up this morning and there are several hanging from my ceiling on a long single strand of silk or web. Is this unusual? Its really weird.: Most okorder

Q: When you're training to work in construction, do you need to do a seperate course or qualification in order to be able to operate a crane? Or are all construction workers taught it in training?: Of course you need specialised training! Crane operators have to sit several courses in safe crane operations. Crane operators tend to just work cranes and not help with general building work as they earn more money and it is only cost effective to have them on site when they are actually needing to use the crane.

Q: Okay Answers community, I need your help. I recently received a thousand paper cranes for my birthday and I want to know, what's the best way to hang them up (like on fishing line etc.)? Also, at the moment I think I'd like to hang them up in my bedroom, in interesting patterns. Any suggestions for how to arrange the cranes, or other ideas for what to do with a thousand paper cranes? Just remember, I'd like to keep the lot!: use all of them to create one big one (assuming they're all similar)

Q: ok I found an injured crane what do I feed it?: Cranes are omnivores. But I would feed crane with vegetarian stuff like grain, berries, plants, roots, seeds, stems, bulbs, fruits, nuts. But if you want make it non vegetarian then rodents, fish, amphibians, snakes, rodents, lizards, small fish, frogs, shellfish, mollusks and crustaceans.

Q: River? Please give me links. I have seen some videos on youtube about the plane getting lifted out, but none of the crane which is what I was wanting to see.: The best link I can find is this first one, the second may create more jobs tho...

Q: For anyone who has read/studied Stephen Crane - do you know of any connecting theme within his most famous short stories (the open boat, the blue hotel, the bride comes to yellow sky, the monster)?I was think naturalism b/c it is so prevalent in the open boat but is really the only short story naturalism is in: sorry, i haven't read any Crane short stories, but i'm a HUGE fan of his poetry. it's some of the most bleak, raw, yet honest poetry i've ever read.

Q: mobile tower etc (uk): Tower cranes and Gantry Cranes Since toer cranes are the most used in the construction industry gantry Cranes are used in all Ports for loading and unloading containers has a vast scope of work
