Q: How would the environment, habitat, or ecosystem be affected if whooping cranes were extinct?: Whooping cranes ARE a part of the food chain..every animal on the planet is....Nata has NO clue what they are talking about. And I HAVE seen a whooping crane before..in the wild while working in Florida. Only 6 existed on the refuge I was working on and I was lucky enough to see 4 of them. It is something I will never forget! If we lost this bird, the animals it feeds on may increase in numbers causing plagues, and other birds that may live and feed in similar habitats may become too plentiful as well since they would have no competition from the cranes. Those birds could in turn wipe out other species. There are also many changes that might take place that we could not even guess at...until it actually happened. This is often the case as we still do not have a great understanding of how one species affects another. But all species DO affect one another, think of each species as a link in a chain, or a strand in a spider web. If you start snipping strands in a web, or damaging or breaking links, what do you think will happen. They will weaken and collapse and eventually fall apart.

Q: how is a tall crane constructed? how can they put the crane on top of its tall body frame?: They first construct the top of crane on the ground with help from other mobile cranes. This includes the long horizontal part with the operator's cab, and the concrete counterweight. this is then placed on a climber, with which the crane kind of builds and climbs itself to the necessary height. Every vertical section of the crane is placed in the climber. When the piece is in place, the climber climbs to the top of piece from where the next vertical piece is placed and so on. You can see how a crane is constructed in the website I've cited below:

Q: in the short story open boat by stephen crane how does he define Fate?: Without doing your work for you, Crane is a naturalist. They believe nature works at random, and is completely unsympathetic to man's plight in the process. Hence, the oiler dies. He was probably the strongest one in the boat. So, how does that translate into the concept of fate?

Q: Which Kung Fu influenced Shotokan, Shito-ryu and Shorin-ryu?: i okorder /

Q: What do you think of this?A teenage boy giving a girl 1000 paper cranes to show his love for her, despite the fact that she previously said she just wanted to be friends. They are 14. He just wants to prove it to her that he is unlike any other boy.: Thats sweet, but I suggest picking the best and the most prettiest one out and tell her.. Reminds me of you... Cheesy but the beauty has to be obivous... It cant be like ugly or just a normal crane. 1,000cranes would .. Well no offense... Make him look like a weirdo who would spend his time making cranes.. But make one HELLA GOOD ONE.

Q: across the street from my work, there are three big cranes. It seems like they just popped up over night. anyone know how they get them built?: If okorder /.. Crawler cranes/ have tracks like a bulldozer/ normally have a larger lifting capacity and are brought to the work site on multiple semi-trucks. Then put together with smaller cranes. Hope this answers most of your questions. Wingman

Q: I have a Manfrotto/Bogen 055XB tripod that says it supports up to about 15lbs. The crane I'm looking into getting is the Glidecam Camcrane 200 which says it has a payload of up to 30lbs. depending on the height. What would happen if I were to use this crane with my tripod?: Please let me know where you will be so I can capture the video of your camera crashing to the ground. Because you overloaded the tripod, there will be no warranty coverage for anything. Yes, they can tell. ++++++++++++ I realized I had not provided an alternative... the crane specs also specify Camcrane 200 mounts on the 3/8 standard bolt found on the majority of medium and heavy duty tripods an

Q: I don't like the crane stock because it looks funny but if you can see the wires when you use a PEQ box I'd prefer a crane stock: I okorder

Q: What type of crane done the lift?what type of object was the crane lifting?what was the weight of the load being lifted?: the lift capacity of the Crane is pretty much dictated by the type of crane it is. The largest Gantry / Bridge type is capeable of 1,500 tons.. the largest tower is 100 tons w. a 100meter turning radius. Tracked lattice boom type is 1,600 tons...........(self contained) there's one that will do 4000 tons with modifications including seperate tracks for counterweights

Q: do they start with the crane house and keep adding sections underneath it? Or do they build they tower and then somehow top it with the actual crane?: How Do They Grow? Tower cranes arrive at the construction site on 10 to 12 tractor-trailer rigs. The crew uses a mobile crane to assemble the jib and the machinery section, and places these horizontal members on a 40-foot (12-m) mast that consists of two mast sections. The mobile crane then adds the counterweights. The mast rises from this firm foundation. The mast is a large, triangulated lattice structure, typically 10 feet (3.2 meters) square. The triangulated structure gives the mast the strength to remain upright. To rise to its maximum height, the crane grows itself one mast section at a time! The crew uses a top climber or climbing frame that fits between the slewing unit and the top of the mast. Here's the process: The crew hangs a weight on the jib to balance the counterweight. The crew detaches the slewing unit from the top of the mast. Large hydraulic rams in the top climber push the slewing unit up 20 feet (6 m). The crane operator uses the crane to lift another 20-foot mast section into the gap opened by the climbing frame. Once bolted in place, the crane is 20 feet taller! Once the building is finished and it is time for the crane to come down, the process is reversed -- the crane disassembles its own mast and then smaller cranes disassemble the rest.
